Extract VoIP audio AFTER started call

0

Excuse me for my not perfect english. I have recorded some Calls becouse my ISP and I have problems (tech).

But I cant extract any audio from VoIP calls. I have asked google, and I found the problem.

I must start Wireshark recording, then do any Call via VoIP. And I started a Call, then started Wireshark recording.

Have I any chance to get Audio from the Wireshark recordings with my fault?

Try setting the RTP preference (Edit->Preferences->Protocols->RTP) "Try to decode RTP outside of conversations". This will make the RTP dissector try to heuristically recognize UDP packets as RTP instead of relying on signaling (e.g., SIP) to tell it which UDP packets to look at.
