I know that OpenSER is a stateless SIP Proxy, that means that if I have a conversation between 2 SIP Phones on the same local network, THERE is no traffic on the SIP Proxy server, and all the traffic takes part between the phones… So there is no load on the SIP Proxy Server.
NOW… The Asterisk part… If I am using Asterisk as a SIP Server, I heard it acts as a statefull SIP Proxy, taking responsability on the communicaitons. Does that means that it acts as “Midlle in the man” server, and all the traffic, including RTP traffic, has to go trhought it ?
That it means that a conversation between 2 phones on the same network is managed and gestionated by Asterisk, and therefore, the server has to asume that LOAD ?
Thks for your clarifications
