Hi Sam,

There are two ways to decode I know about:

1. Dump in ad-hoc format, decode with extractaudio tool, which is still work-in-progress, so we have not really released it yet. Latest code is available here http://bitbucket.org/sippysoft/rtpproxy/. Subdir "extractaudio". It might not even compile out of the box, but that could be easily fixed

2. Dump in the pcap format (rtpproxy has an option for that), and fiddle around with the wireshark and friends. It has pretty decent rtp decoder, I am not sure if you can script it though.

The caller/callee info can be passed through file name using AVPs, or some side channel and linked to file name by call-id.
