[Serusers] call recording app

Hi all, I got a job now, I need to build a call recording application, what stores the rtp streams of the calls, what routed to the application. There is an existing routing logic (special sip proxy) what decides if the call should be recorded or not. If the call needs to be recorded, this proxy will route the call to this recorder application. This app needs to send through the call to the next sip hop, but it must store the RTP streams on the fly. What we have now: - we have our own rtpproxy, we can modify it easily if we need to store the streams. - we have our own B2BUA what controls the rtpproxy I just wondering if we can use SER + SEMS for this, or should we build our own system ? What should be the most effective way ? Can it be done with SEMS easily ? Thanks for the suggestions, recommendations. Misi
