I tried

 ffmpeg -loglevel debug -f rtp -c:a opus -i call2.rtpdump -ar 48000
call2.mp3

does that look right?

I get 'Unsupported RTP version packet received' and a whole bunch of
'Received too short packet' so perhaps my data is bad.

But I am wondering where/how to give ffmpeg the sdp information so it will
now how to decode the payload types etc
