tcpdump udp port 5060 -s0 -A will give you all the SIP. But just dumping all traffic between asterisk and the host will give you a view on RTP - you should see it take off when a call is setup if its not blocked You should see a SIP Invite to setup a call with the audio destination - this should be your asterisk box and the far end depending on who is doing what. You should look at the address and also whether both sides are providing a mutually acceptable audio formats. If there are no agreed audio formats you won't get rtp. The c= in the session setup indicates the addresses each site is using for media.
