Hi!

I'm trying to listen call audio from multiple traffic captures, but the RTP player does not show any waves of sound and obviously doesn't reproduce anything, even though it recognized that there are phone conversations within the packets.

I've been trying all I found on the internet, but nothing works.

I see 3 voip calls, press play, RTP player open showing rtp streams, and blank wave panel, i tried to reproduce rtp streams, nothing happens. Maybe the problem is the Payload type/encoding (GSM)?
