ReplaceMessage Method
Replaces a previously sent message with a new one.
Syntax
smpp.replaceMessage(messageId, newMessage, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
Assuming that there is a message on the SMPPServer stored under the value in MessageId, this method will replace that message with the value in NewMessage.
If there is no message corresponding to MessageId, the SMS service will respond with an error message.
