Avaya SBC receives RTCP streams from a SIP trunk that does not have any Avaya specific control information. Avaya SBC converts RTCP streams into Avaya specific format and sends it to the quality monitoring server.
Important:
RTCP monitoring generation is applicable only for SIP trunks.
Avaya SBC calculates Round Trip Time based on the RTCP streams coming from a SIP trunk or from a enterprise network.
Avaya SBC generates the RTCP monitoring report and sends it to the RTCP monitoring server. RTCP monitoring server can be configured from the web interface. At the quality monitoring server, you can calculate Mean Opinion Score (MOS) from Round Trip Time.
