Re: [SR-Users] Need help understanding/separating signaling from media

Hello Alex, Thank you for the explanation. It's clear to me now. One more thing, I've read that it's not recommended to have media being handled by virtual servers, is this also the case when using rtpproxy? We are using VMWare for virtualization.

The rtpproxy process answers, and Kamailio then writes the IP and ports provided by rtpproxy into the SDP of both the requests and replies involved in setting up the call. The result is that as far as both UAs are concerned, rtpproxy is their endpoint, and they will send media to it. Kamailio instructs rtpproxy to bridge both streams. When the call is torn down, Kamailio tells rtpproxy to disengage and deallocate the bridge mapping for those streams. -- Alex [1] Which may be running on the same host, or may be running on another host, in a distributed fashion. Kamailio talks to rtpproxy through rtpproxy's UDP control socket, and more than one rtpproxy may be used, both for failover and round-robin load distribution. This is readily baked into the rtpproxy module. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
