I would suggest you ensure you use a snaplen in tcpdump that is large enough to capture all the packet information. Once you have the captured data you will find Wireshark is your friend, open the file in Wireshark and then select "VoIP Calls" which is located under the Telephony menu item. Once it has gathered the information it wants you will be able to select one ore more sessions, once selected click on the Flow button, all will now be clear! Larry.
