SipReceived100Trying

 

This event informs the application software that the far end SIP device has responded to an invitation to take part in a call. The far end is stating that it is "Trying" to process the call request.

Note:
If your VOIP application uses a SIP proxy server, this event will most likely be sent to the application when the call request is first processed by your proxy server and not by the SIP call endpoint.
