Hi, Let me explain what I'm looking for a solution using asterisk. I have one third party SIP based server (A) and on Asterisk server (B). 1. Extension-1 --> Server A calls Server B. 2. Server B does some processing and calls/sends back to Server A ---> Extension-2 3. SIP session has been established b/w two Extension-1 and Extension-2. Now is there any config that I can do in sip.conf which causes direct sip/rtp communication between Extension-1 and Extension-2 without involving Server-B Exten-1-------> | | Server A | <---->|ServerB | Exten-2<------- | -ag -------------- next part -------------- An HTML attachment was scrubbed...
