How does the voice over IP (VoIP) process model internally work?

Solution

Internally, voice packets are sent over Real-time Transport Protocol (RTP) streams. No special configuration is required for RTP. By default, no signaling is enabled; however, either SIP or H.323 can be enabled for signaling. This is set by the attribute Voice->Signaling on the Application Config node.The voice application includes two process models:- gna_voice_called_mgr:This is spawned directly by gna_clsvr_mgr in all client models. There is always a passive gna_voice_called_mgr process running.- gna_voice_calling_mgr:This is spawned by the gna_profile_mgr when a voice call is generated. This process will contact a gna_voice_called_mgr process to establish a call.
