In this pcap file, I can find RTP, RTCP, and STUN packets. I tried to check which packet does negotiate for the codec, but couldnt find it. Can you please share any idea, where should I look to find this negotiation ?

Some observations here:
This leads me to believe that the UDP packets also contain some form of encrypted communication, which could be the VoIP packets you are looking for, but which won't reveil there contents.
