The IPPhone class can be used to implement a software-based phone.
Syntax
IPPhone
Remarks
The IPPhone class can be used to implement a software-based phone utilizing modern Voice over Internet Protocol (VoIP) technology. This softphone is able to perform many different functions of a traditional telephone, such as making and receiving calls, performing blind and attended transfers, placing calls on hold, establishing and joining conferences, and more.
Registration
To begin, the first step is activating, or registering, the class. The Server, Port, User, and Password properties must be set to the appropriate values to register with your SIP server/provider. After these values are set, call Activate. If the class has successfully activated/registered, the Activated event will fire and Active will be set to true. The class will now be able to make/receive phone calls. For example:ipphone1.OnActivated += (o, e) => {
Console.WriteLine("Activation Successful");
};
ipphone1.User = "sip_user";
ipphone1.Password = "sip_password";
ipphone1.Server = "sip_server";
ipphone1.Port = 5060 // Default, 5061 is typical for SSL/TLS
ipphone1.Activate();
Additionally, it's important to note that the registration of a SIP client will expire if not refreshed. The expiration time is negotiated with the server when registering.
By default, the class will attempt to negotiate a value of 60 seconds. This value can be changed via the RegistrationInterval configuration.
Note this is merely a suggestion to the server, and the server can change this accordingly. If the server does change this, after registration is complete, RegistrationInterval will be updated.
To prevent the registration from expiring, the class will refresh the registration within DoEvents, when needed. To ensure this occurs, we recommend calling DoEvents frequently. In a form-based application, we recommend doing so within a timer. For example, this could look something like:
private void timer1_Tick(object sender, EventArgs e)
{
ipphone1.DoEvents();
}
private System.Windows.Forms.Timer timer1;
timer1.Interval = 1000;
timer1.Tick += new System.EventHandler(this.timer1_Tick);
timer1.Enabled = true;
Note that in console applications, you must call DoEvents in a loop in order to provide accurate message processing, in addition to this case.
Audio Setup
While not required to function, you may set the microphone and speaker for the class to use during calls. First, you must call ListMicrophones and ListSpeakers. Doing so will populate the Microphone* properties and the Speaker* properties. Once this is done, you can set these devices via SetMicrophone and SetSpeaker given their device name. For example:ipphone1.ListMicrophones();
ipphone1.ListSpeakers();
foreach (Speaker s in ipphone1.Speakers) {
Console.WriteLine("Speaker Name: " + s.Name);
}
foreach (Microphone m in ipphone1.Microphones) {
Console.WriteLine("Microphone Name: " + m.Name);
}
ipphone1.SetSpeaker(ipphone1.Speakers[0].Name);
ipphone1.SetMicrophone(ipphone1.Microphones[0].Name);
Security
By default, the class operates in plaintext for both SIP signaling and RTP (audio) communication. To enable completely secure communication using the class, both SIPS (Secure SIP) and SRTP (Secure RTP) must be enabled.
Enable SIPS
To enable SIPS (Secure SIP, or SIP over SSL/TLS), the SIPTransportProtocol property must be set to 2 (TLS). The Port property will typically need to be set to 5061 (this may vary). Additionally, the SSLServerAuthentication event must be handled, allowing users to check the server identity and other security attributes related to server authentication. Once this is complete, the class can then be activated. All subsequent SIP signaling will now be secured. For example:
ipphone1.OnSSLServerAuthentication += (o, e) => {
if (!e.Accept) {
if (e.CertSubject == "SIPS_SAMPLE_SUBJECT" && e.CertIssuer == "SIPS_CERT_ISSUER") {
e.Accept = true;
}
}
};
// Enable SIPS
ipphone1.SIPTransportProtocol = IpphoneSIPTransportProtocols.tpTLS;
ipphone1.User = "sip_user";
ipphone1.Password = "sip_password";
ipphone1.Server = "sip_server";
ipphone1.Port = 5061; // 5061 is typical for SSL/TLS
ipphone1.Activate();
Information related to the SSL/TLS handshake will be available within the SSLStatus event with the prefix [SIP TLS].
Enable SRTP
While the above process secures SIP signaling, it does not secure RTP (audio) communication. The RTPSecurityMode property can be used to specify the security mode that will be used when transmitting RTP packets. By default, this property is 0 (None), and RTP packets will remain unencrypted during communication with the remote party.
To ensure the audio data is encrypted and SRTP is enabled, the RTPSecurityMode must be set to either of the following modes: 1 (SDES), or 2 (DTLS-SRTP). The selected mode will be used to securely derive a key used to encrypt and decrypt RTP packets, enabling secure audio communication with the remote party. The appropriate mode to use may depend on the service provider and configuration of a particular User. For example:
ipphone1.OnSSLServerAuthentication += (o, e) => {
if (!e.Accept) {
if (e.CertSubject == "SIPS_SAMPLE_SUBJECT" && e.CertIssuer == "SIPS_CERT_ISSUER") {
e.Accept = true;
}
}
};
ipphone1.RTPSecurityMode = IpphoneRTPSecurityModes.etSDES; // Enable SRTP (SDES)
//ipphone1.RTPSecurityMode = IpphoneRTPSecurityModes.etDTLS; // Enable SRTP (DTLS-SRTP)
ipphone1.SIPTransportProtocol = IpphoneSIPTransportProtocols.tpTLS;
ipphone1.User = "sip_user";
ipphone1.Password = "sip_password";
ipphone1.Server = "sip_server";
ipphone1.Port = 5061; // 5061 is typical for SSL/TLS
ipphone1.Activate();
ipphone1.Dial("123456789", "", true);
Note it is highly recommended that SIPTransportProtocol is set to TLS when enabling SRTP. Additionally, if SRTP is enabled, the remote party must support the selected mode, otherwise no call will be established.
Managing Calls
All incoming and outgoing calls currently recognized by the class will be stored in the Call* properties. These connections will be initiated or accepted through the interface identified by LocalHost and LocalPort.Incoming Calls
After successful activation, incoming calls will be detected, and IncomingCall will fire for each call. Within this event, Answer, Decline, or Forward can be used to handle these calls. For example:
ipphone1.OnIncomingCall += (o, e) => {
ipphone1.Answer(e.CallId);
};
Outgoing Calls
To make an outgoing call, you must use Dial. This method takes three parameters: the user you wish to call, your caller ID (optional), and a boolean that determines whether the method will connect synchronously (True) or asynchronously (False). If set, the second parameter will cause P-Asserted-Identity headers (RFC 3325) to be sent in requests to the server. If left as an empty string, this header will not be sent. Dial will return a call identification string (Call-ID) that is unique to the call. After the method returns successfully, the call will be added to the Call* properties.
Please see the method description for detailed examples on using Dial synchronously and asynchronously.
Transferring Calls
Ongoing calls can be transferred using Transfer. The class supports two types of transfers:Basic (Blind) Transfers
Basic transfers are very simple to perform. First, the user establishes a call with the number they will be transferring (transferee). After the call is established, the user can transfer the call to the appropriate number (transfer target). The call will then be removed. For example:
string callId = ipphone1.Dial("123456789", "", true); // Establish call with transferee, hold if needed
//ipphone1.Hold(callId);
ipphone1.Transfer(callId, "number");
Attended Transfers
Typically, attended transfers are used to manually check if the "number" they are transferring to (transfer target) is available for a call, provide extra information about the call, etc., before transferring. In addition to establishing a call with the transferee, the class must also establish a call with the transfer target. Once both calls are active, you may perform an attended transfer by calling Transfer at any moment. Afterwards, a session will be established between both calls, and they will be removed. Note that Transfer must be used with the callId of the call you wish to transfer (transferee) and the number of the call you wish to transfer to (transfer target). For example:
string callId1 = ipphone1.Dial("123456789", "", true); // Establish call with Transferee, hold if needed
//ipphone1.Hold(callId1);
string callId2 = ipphone1.Dial("number", "", true); // Establish call with Transfer Target, hold if needed
//ipphone1.Hold(callId2);
ipphone1.Transfer(callId1, "number");
Note in these examples, Hold can be used to place a call on hold before a transfer. This is optional.
Audio Playback
The class supports three methods of playing audio to a call, being PlayFile, PlayText, or PlayBytes. Note for each of these methods, audio transmission will only occur when the call has connected and CallReady has fired. Additionally, only audio data with a sampling rate of 8 kHz and a bit depth of 16 bits per sample can be played (PCM 8 kHz 16-bit format). Also note that these methods are non-blocking, and will return immediately. The class can also handle playing audio to concurrent calls.PlayFile can be used to play audio from a WAV file to a specific call. PlayText can also be used to play audio, but will do so using Text-to-Speech. Once audio has finished playing, Played will fire.
PlayBytes can be used to play audio, but will do so in an event-based manner. The behavior of PlayBytes is very different from the previous two methods. For a detailed description on how to use this method with the Played event, please see the method and event descriptions.
Recording Audio
Ongoing calls can be recorded using StartRecording. The audio can be recorded directly to a WAV file by specifying the filename parameter. Additionally, if the filename parameter is not specified, the audio will be recorded internally, and made available once the recording is finished. The recorded data will be available within the Record event.
Note in both scenarios, the recording will end either when the call is terminated, or StopRecording is called. The recorded audio will have a sampling rate of 8 kHz and a bit depth of 16 bits per sample (PCM 8 kHz 16-bit format).
Example: Using the 'Record' event
MemoryStream recordStream = new MemoryStream();
phone.StartRecording("callId", "");
phone.OnRecord += (o, e) => {
recordStream.Write(e.RecordedDataB, 0, e.RecordedDataB.Length);
File.WriteAllBytes(recordFile, recordStream.ToArray());
};
Conferencing
The class also supports conferencing. A call can join a conference using the JoinConference method, passing in the callId of the call and the custom conferenceId. If the conferenceId does not exist, then a new conference will be created given this ID. Other calls can then join the existing conference with this same ID.
To monitor existing conferences, the ListConferences method will return a string containing all ongoing conferences and calls within each conference. This value will have the following format:
ConferenceId_1: CallId_1, CallId_2
...
ConferenceId_n: CallId_3, CallId_4, CallId_5, ...
At any moment, a call can be removed from a conference using LeaveConference. If the user is the last call within the conference, then the conference will be removed.
Call Termination
Ongoing calls are terminated by passing the appropriate Call-ID to Hangup. All ongoing calls can be terminated with HangupAll. When a call has been terminated (by either party), CallTerminated will fire. It's important to note that in the case where an outgoing call is never answered, the class will attempt to leave a voicemail. The voicemail will end once Hangup or HangupAll is called, and CallTerminated will fire.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).
NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

int ipworksvoip_ipphone_getlocalport(void* lpObj);
int ipworksvoip_ipphone_setlocalport(void* lpObj, int iLocalPort);
int GetLocalPort();
int SetLocalPort(int iLocalPort);
Default Value
0
Remarks
The LocalPort property must be set before UDP is activated (Active is set to True). It instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting it to 0 (default) enables the TCP/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.
LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.
The LocalPort property is useful when trying to connect to services that require a trusted port in the client side.

Activate Method (IPPhone Class)
Activates the class.
Syntax
ANSI (Cross Platform) int Activate(); Unicode (Windows) INT Activate();
int ipworksvoip_ipphone_activate(void* lpObj);
int Activate();
Remarks
This method is used to activate the class by registering to a SIP Server specified in the Server and Port properties. The username and password of the SIP Server must be provided via User and Password properties for authorization, if applicable.
Example:
ipphone.User = "MyUsername";
ipphone.Password = "MyPassword";
ipphone.Server = "HostNameOrIP";
ipphone.Port = 5060;
ipphone.Activate();
Upon successful activation, the Activated event will fire.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Answer Method (IPPhone Class)
Answers an incoming phone call.

Config Method (IPPhone Class)
Sets or retrieves a configuration setting.
Syntax
ANSI (Cross Platform) char* Config(const char* lpszConfigurationString); Unicode (Windows) LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworksvoip_ipphone_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Error Handling (C++)
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
Deactivate Method (IPPhone Class)
Deactivates the class.
Syntax
ANSI (Cross Platform) int Deactivate(); Unicode (Windows) INT Deactivate();
int ipworksvoip_ipphone_deactivate(void* lpObj);

Remarks
This method is used to unregister the class from the SIP Server. If deactivation is successful, Deactivated will fire.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Decline Method (IPPhone Class)
Declines an incoming phone call.
Syntax
ANSI (Cross Platform) int Decline(const char* lpszcallId); Unicode (Windows) INT Decline(LPCWSTR lpszcallId);
int ipworksvoip_ipphone_decline(void* lpObj, const char* lpszcallId);
int Decline(const QString& qscallId);
Remarks
This method can be used to decline an incoming phone call, specified by callId. This method can
be used in conjunction with the IncomingCall event, for example:
ipphone.onIncomingCall += (sender, e) => {
ipphone.Decline(e.CallId);
};
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
Dial Method (IPPhone Class)
Used to make a call.
Syntax
ANSI (Cross Platform) char* Dial(const char* lpsznumber, const char* lpszcallerNumber, int bwait); Unicode (Windows) LPWSTR Dial(LPCWSTR lpsznumber, LPCWSTR lpszcallerNumber, BOOL bwait);
char* ipworksvoip_ipphone_dial(void* lpObj, const char* lpsznumber, const char* lpszcallerNumber, int bwait);
QString Dial(const QString& qsnumber, const QString& qscallerNumber, bool bwait);
Remarks
This method is used to make a call to a particular user, given by number. This method should only be called after the class has been successfully activated via Activate. Initially, the OutgoingCall event will fire after calling this method. DialCompleted may fire when the dial process is complete. If successful, CallReady will fire after the outgoing call has been answered, declined, or ignored. If the call is declined or ignored, the class will be sent to voicemail, which can be ended with Hangup.
The callerNumber parameter specifies the optional caller ID. If given, the P-Asserted-Identity Header, specified in RFC 3325, will be sent in requests to the connected SIP Server. If left as an empty string, this header will not be sent.
The wait parameter specifies whether the class should connect synchronously or asynchronously to the call. If True, the class will connect synchronously, and won't return until the call has been answered, declined, or ignored. If False, the class will connect asynchronously. The call's status can be checked through various events, such as OutgoingCall, CallReady, and CallStateChanged, or found in the call's State field. Exceptions throughout the call process will be reported in DialCompleted, along with other call details.
NOTE: This method will return the CallId field of the call. This returned value may not always reflect the accurate CallId. In the case that wait is true, this method will always return the accurate value. In the case that wait is false, the returned value may not be accurate if the outgoing call is forwarded, or redirected, as the class must change this field. Both the updated and original CallId will be present within the DialCompleted event. Any references to the original CallId must be updated accordingly. Please see DialCompleted for more details. The below examples assume the outgoing call has been answered:
Example: "wait" is true
string callId = "";
bool connected = false;
ipphone.OnCallReady += (sender, e) => {
connected = true;
}
try {
callId = ipphone.Dial("123456789", "", true);
} catch (IPWorksVoIPException e) {
MessageBox.Show(e.Code + ": " + e.Message);
}
if (connected) {
ipphone.PlayText(callId, "Hello");
}
Example: "wait" is false
bool connected = false;
string callId = "";
ipphone.OnDialCompleted += (sender, e) => {
if (e.ErrorCode != 0) {
MessageBox.Show(e.ErrorCode + ": " + e.Description);
// Handle error
}
if (e.OriginalCallId != e.CallId) {
callId = e.CallId; // Update callId if redirect occurred
}
}
ipphone.OnCallReady += (sender, e) => {
connected = true;
}
string callId = ipphone.Dial("123456789", "", false);
...
...
...
// Somewhere else...
if (connected) {
ipphone.PlayText(callId, "Hello");
}
Error Handling (C++)

int ipworksvoip_ipphone_playbytes(void* lpObj, const char* lpszcallId, const char* lpbytesToPlay, int lenbytesToPlay, int blastBlock);
int PlayBytes(const QString& qscallId, QByteArray qbabytesToPlay, bool blastBlock);
Remarks
This method is used to play bytes to a call, specified by the callId parameter. These bytes are expected to have a sampling rate of 8 kHz and a bit depth of 16 bits per sample (PCM 8 kHz 16-bit format). The bytesToPlay parameter specifies the bytes that will be sent to the call. Internally, these bytes will be stored within a buffer. Once all bytes have played and the buffer is empty, the Played event will fire.
The lastBlock parameter indicates whether the class will expect further uses of PlayBytes. When true, this indicates that no additional bytes will be provided for this particular audio stream, and Played will fire once after the bytes have been played. Until this parameter is specified as true, the class will be considered to be playing audio.
If lastBlock is false, this indicates that the class should expect more calls to PlayBytes. Once all bytes have played and the buffer is empty, Played will fire as expected, and will continue firing until the lastBlock parameter is set to true. Within Played, the user can provide further bytes to PlayBytes. Please see below for detailed examples on how to use this method with Played.
Example: Playing audio from a stream
MemoryStream playBytesStream = new MemoryStream(byteSource);
phone.PlayBytes("callId", new byte[0], false);
phone.OnPlayed += (o, e) => {
if (e.Completed) {
Console.WriteLine("Playing Bytes Completed");
} else {
byte[] data = new byte[4096]; // Arbitrary length
int dataLen = playBytesStream.Read(data, 0, data.Length);
if (dataLen > 0) {
byte[] newData = new byte[dataLen];
Array.Copy(data, newData, dataLen) // Normalize array
phone.PlayBytes(e.CallId, newData, false);
} else {
phone.PlayBytes(e.CallId, null, true);
}
}
};
Exmaple: Playing single audio block
MemoryStream playBytesStream = new MemoryStream(byteSource);
phone.PlayBytes("callId", playBytesStream.ToArray(), true);
phone.OnPlayed += (o, e) => {
Console.WriteLine("Done!"); // No further calls to PlayBytes are expected in this case
}
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
PlayFile Method (IPPhone Class)

int ipworksvoip_ipphone_playfile(void* lpObj, const char* lpszcallId, const char* lpszwavFile);
int PlayFile(const QString& qscallId, const QString& qswavFile);
Remarks
This method is used to play the audio from a WAV file to a particular call, given by callId. Audio transmission will only occur when the call has connected and CallReady has fired. Only WAV files with a sampling rate of 8 kHz and a bit depth of 16 bits per sample are supported (PCM 8 kHz 16-bit format).
Note that this class can handle playing audio to concurrent calls. This method is non-blocking and will return immediately. The Played event will fire when the audio for the specified call has finished playing. Consecutive uses of PlayText or PlayFile can prevent prior audio transmissions from being completed. In the below example, Played will only fire for the second call to PlayText:
ipphone.PlayFile("callId", "C:\\hello.wav"); // Played will not fire for this
ipphone.PlayText("callId", "This will interrupt the previous use if it has not finished playing.");
The wavFile parameter specifies the path to the WAV file.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

StartRecording Method (IPPhone Class)
Used to start recording the audio of a call.
Syntax
ANSI (Cross Platform) int StartRecording(const char* lpszcallId, const char* lpszfilename); Unicode (Windows) INT StartRecording(LPCWSTR lpszcallId, LPCWSTR lpszfilename);
int ipworksvoip_ipphone_startrecording(void* lpObj, const char* lpszcallId, const char* lpszfilename);
int StartRecording(const QString& qscallId, const QString& qsfilename);
Remarks
This method is used to start recording the incoming and outgoing audio of a call, specified by callId. If you wish to record the audio to file, you may specify the filename parameter. Note that when this parameter is specified, you must record to a WAV file.
You may also leave the filename parameter blank if you want more direct control over the recorded data. This will cause the Record event to fire containing the call's audio data once the recording is finished.
In both scenarios, you can stop recording the call's audio via StopRecording. By default, the recording will end if the call is terminated. Note the recorded audio will have a sampling rate of 8 kHz and a bit depth of 16 bits per sample (PCM 8 kHz 16-bit format).
Example: Using the 'Record' event
MemoryStream recordStream = new MemoryStream();
phone.StartRecording("callId", "");

int ipworksvoip_ipphone_transfer(void* lpObj, const char* lpszcallId, const char* lpsznumber);
int Transfer(const QString& qscallId, const QString& qsnumber);
Remarks
This method is used to transfer a call, specified by callId, to the phone number given by number. The class supports the following types of transfers:
Basic Transfers
Basic transfers are very simple to perform. First, the user must establish a call with the number they will be transferring (transferee). After the call is established, the user can transfer the call to the appropriate number (transfer target). The call will then be removed. For example:
string callId = ipphone1.Dial("123456789", "", true); // Establish call with transferee, hold if needed
//ipphone1.Hold(callId);
ipphone1.Transfer(callId, "number");
Attended Transfers
Typically, attended transfers are used to manually check if the number (or transfer target) is available for a call, provide extra information about the call, etc., before transferring. In addition to establishing a call with the transferee, the class must also establish a call with the transfer target. Once both of these calls are active, you may perform an attended transfer by calling Transfer at any moment. Afterwards, a session between these calls will be established and they will be removed. Note that Transfer must be used with the callId of the call you wish to transfer (transferee) and the number of the call you wish to transfer to (transfer target). For example:
string callId1 = ipphone1.Dial("123456789", "", true); // Establish call with Transferee, hold if needed
//ipphone1.Hold(callId1);
string callId2 = ipphone1.Dial("number", "", true); // Establish call with Transfer Target, hold if needed
//ipphone1.Hold(callId2);
ipphone1.Transfer(callId1, "number");
Note in these examples, Hold can be used to place a call on hold before a transfer. This is optional.
Error Handling (C++)
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

class IPPhoneDialCompletedEventParams { public: const QString &OriginalCallId(); const QString &CallId(); const QString &Caller(); const QString &Callee(); int ErrorCode(); const QString &Description(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void DialCompleted(IPPhoneDialCompletedEventParams *e);
// Or, subclass IPPhone and override this emitter function. virtual int FireDialCompleted(IPPhoneDialCompletedEventParams *e) {...}
Remarks
This event will fire when the dial process, initiated by calling Dial, has completed. Note that this event will not fire if an exception occurs when the "wait" parameter of Dial is true. In this case, the class will throw an exception. However, it will fire if "wait" is true and no exception occurs, indicating Dial was successful.
The OriginalCallId parameter is the value returned by Dial.
The value of the CallId parameter depends on the redirection status of the call. There are two scenarios:
- The outgoing call has not been redirected. In this case, CallId is equal to OriginalCallId, and the value returned by Dial is correct.
- The outgoing call has been redirected any number of times. In this case, the OriginalCallId is no longer applicable, and the CallId parameter is the new unique identifier for this call. Any reference to the past value, OriginalCallId, should be updated accordingly to reflect the change due to redirection. This would also include references to the original value returned by Dial.
Errors during the dial process are reported via the ErrorCode and Description parameters. An error code of 0 and description of "Dialed Successfully" indicate Dial has completed with no issues. A list of error codes can be found in the Error Codes section. In the case of a non-zero ErrorCode, the Description parameter will contain the error message (and SIP response code, if applicable), for example, "Dial Timeout" or "486: Busy Here".
Digit Event (IPPhone Class)

The CallId parameter is the unique Call-ID of the call.
The RemoteUser parameter indicates the username or telephone number of the remote user associated with the call.
Played Event (IPPhone Class)
This event is fired after the class finishes playing available audio.
Syntax
ANSI (Cross Platform) virtual int FirePlayed(IPPhonePlayedEventParams *e);
typedef struct {
const char *CallId;
int Completed; int reserved; } IPPhonePlayedEventParams;
Unicode (Windows) virtual INT FirePlayed(IPPhonePlayedEventParams *e);
typedef struct {
LPCWSTR CallId;
BOOL Completed; INT reserved; } IPPhonePlayedEventParams;
#define EID_IPPHONE_PLAYED 12 virtual INT IPWORKSVOIP_CALL FirePlayed(LPSTR &lpszCallId, BOOL &bCompleted);
class IPPhonePlayedEventParams { public: const QString &CallId(); bool Completed(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Played(IPPhonePlayedEventParams *e);
// Or, subclass IPPhone and override this emitter function. virtual int FirePlayed(IPPhonePlayedEventParams *e) {...}
Remarks
The Played event will fire after the class finishes playing available audio to a call. When using PlayText or PlayFile, Completed will always be true. However, this will not always be the case when using PlayBytes.
When playing audio via PlayBytes, this event will fire when the internal byte queue is empty. In the event that the internal byte queue is empty, and the class is still expecting calls to PlayBytes (i.e., lastBlock is false), this event will continue to fire with the Completed parameter as false. In this case, additional bytes are expected to be provided. Completed will be true once all bytes have been played and the class is no longer expecting calls to PlayBytes (i.e., lastBlock is true). Please see the method description for more details.
The CallId parameter is the unique Call-ID of the call.
Record Event (IPPhone Class)
This event is fired when recorded audio data is available.
Syntax
ANSI (Cross Platform) virtual int FireRecord(IPPhoneRecordEventParams *e);
typedef struct {
const char *CallId;
const char *RecordedData; int lenRecordedData; int reserved; } IPPhoneRecordEventParams;
Unicode (Windows) virtual INT FireRecord(IPPhoneRecordEventParams *e);
typedef struct {
LPCWSTR CallId;
LPCSTR RecordedData; INT lenRecordedData; INT reserved; } IPPhoneRecordEventParams;
#define EID_IPPHONE_RECORD 13 virtual INT IPWORKSVOIP_CALL FireRecord(LPSTR &lpszCallId, LPSTR &lpRecordedData, INT &lenRecordedData);
class IPPhoneRecordEventParams { public: const QString &CallId(); const QByteArray &RecordedData(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void Record(IPPhoneRecordEventParams *e);
// Or, subclass IPPhone and override this emitter function. virtual int FireRecord(IPPhoneRecordEventParams *e) {...}
Remarks
This event is fired when a call's recorded data is available. This data is made available when either StopRecording is called or the call is terminated. Note that for this event to fire, StartRecording must be specified with no filename parameter.
The recorded data will be available in the RecordedData and RecordedDataB parameters, and will have a sampling rate of 8 kHz and a bit depth of 16 bits per sample (PCM 8 kHz 16-bit format).
The CallId parameter is the unique Call-ID of the call.
Silence Event (IPPhone Class)
This event is fired when the class detects silence from incoming audio streams.
Syntax
ANSI (Cross Platform) virtual int FireSilence(IPPhoneSilenceEventParams *e);
typedef struct {
const char *CallId; int reserved; } IPPhoneSilenceEventParams;
Unicode (Windows) virtual INT FireSilence(IPPhoneSilenceEventParams *e);
typedef struct {
LPCWSTR CallId; INT reserved; } IPPhoneSilenceEventParams;
#define EID_IPPHONE_SILENCE 14 virtual INT IPWORKSVOIP_CALL FireSilence(LPSTR &lpszCallId);

The CallId parameter is the unique Call-ID of the call.
SSLServerAuthentication Event (IPPhone Class)
Fired after the server presents its certificate to the client.
Syntax
ANSI (Cross Platform) virtual int FireSSLServerAuthentication(IPPhoneSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } IPPhoneSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(IPPhoneSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } IPPhoneSSLServerAuthenticationEventParams;
#define EID_IPPHONE_SSLSERVERAUTHENTICATION 15 virtual INT IPWORKSVOIP_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class IPPhoneSSLServerAuthenticationEventParams { public: const QByteArray &CertEncoded(); const QString &CertSubject(); const QString &CertIssuer(); const QString &Status(); bool Accept(); void SetAccept(bool bAccept); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(IPPhoneSSLServerAuthenticationEventParams *e);
// Or, subclass IPPhone and override this emitter function. virtual int FireSSLServerAuthentication(IPPhoneSSLServerAuthenticationEventParams *e) {...}
Remarks
This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (IPPhone Class)
Shows the progress of the secure connection.
Syntax
ANSI (Cross Platform) virtual int FireSSLStatus(IPPhoneSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } IPPhoneSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(IPPhoneSSLStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } IPPhoneSSLStatusEventParams;
#define EID_IPPHONE_SSLSTATUS 16 virtual INT IPWORKSVOIP_CALL FireSSLStatus(LPSTR &lpszMessage);
class IPPhoneSSLStatusEventParams { public: const QString &Message(); int EventRetVal(); void SetEventRetVal(int iRetVal); };
// To handle, connect one or more slots to this signal. void SSLStatus(IPPhoneSSLStatusEventParams *e);
// Or, subclass IPPhone and override this emitter function. virtual int FireSSLStatus(IPPhoneSSLStatusEventParams *e) {...}
Remarks
The event is fired for informational and logging purposes only. Used to track the progress of the connection.
