@Franklin Cohen i really appreciate your reply. I found the site thru google and I'm in the hacking process atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.

Anyone can answer ?
Does proxies have capability to carry Media ???

[@VoipEngineerTrainingcom]

Yes and no. By default a SIP proxy won't carry media. However, it is 100% possible to use RTP Proxy and Kamailio / SER on the same server.

[@jonhansen3192]

Depends on the proxy, but there are Proxies that do both signalling and media. Generally they like to split the two up though.
