### RSVP and RTCP

Avaya IP Telephones implement the Resource ReSerVation Protocol (RSVP) administered from the media server and the RTP Control Protocol (RTCP). The Avaya Voice over IP (VoIP) Monitoring Manager (VMON) software can then provide real-time monitoring and historical data of audio quality for VoIP calls.

The only way to change these parameters is by appropriate switch administration. For more information, see your Avaya Media Server administration documentation and Administration for Network Connectivity for Avaya Communication Manager (Document Number 555-233-504).
