Examples: RTPEngine

RTPEngine

The Sipwise NGCP rtpengine is a proxy for RTP traffic and other UDP based media traffic. It's meant to be used with the Kamailio SIP proxy and OpenSIPS SIP proxy and forms a drop-in replacement for any of the other available RTP and media proxies.

RTPEngine supports HEP3 Encapsulation and can mirror RTCP packets relayed between streams to HOMER complete with SIP correlation identifiers.

Parameters

 --homer=IP46:PORT           Address of Homer server for RTCP stats
 --homer-protocol=udp|tcp    Transport protocol for Homer (must be defined)
 --homer-id=INT              'Capture ID' to use within the HEP protocol

Setup

Configure RTPEngine to send RTCP reports to Homer using the same settings you used in your Kamailio/OpenSIPS/Captagent configuration:

Example

 --homer=10.0.0.20:9060 
 --homer-protocol=udp  
 --homer-id=999 

/usr/sbin/rtpengine --interface=10.0.0.1 --listen-tcp=25060 --listen-udp=12222 --listen-ng=22222 --listen-cli=9900 --timeout=60 --silent-timeout=3600 --pidfile=/var/run/ngcp-rtpengine-daemon.pid --table=0 --log-level=6 --log-facility=daemon --homer=10.0.0.20:9060 --homer-id=999 --homer-protocol=udp
