I've written two new dissectors to handle V.150.1 traffic (i.e., modem over
IP).  The first is a dissector for parsing SPRT (Simple Packet Relay Transport)
traffic.  The other dissector parses SSE (State Signaling Events) messages,
which ride over RTP & handle the transition between operational modes... that
is, whether SPRT or RTP is being used.  I have also made some changes to both
SDP & RTP to enable support for V.150.1.
As they are now, these dissectors will parse V.150.1 packets & make sense of
them, but I would like to do more work on following conversations & maintaining
state, as well as storing user preferences.
