This was the client sending from port 39409 to server port 13429, which
is in the range. From what I read, the rtpstart and rtpend define the
range that is available for use on the server, so I'm not sure this will
apply.
But, I've set my range to 5000 - 40000. I'll find out tomorrow if it
makes any difference.
Where is a good place to find documentation on the various fields in the
INVITE SIP message and the response? I'd like to dig into them and try
to understand them more completely.

have you changed port range? if no then
your client sending rtp to a port higher then configured in rtp port
range and asterisk ignore that port.
try to change rtpend=30000 or if there is option in
softphone restrict it to use same range as in rtp.conf.
let me know if this solve you problem.

We have Ubuntu 12.04 clients, using either SFLPhone or Bria 3.
There is no NAT involved in the network at all (it is disabled
in sip.conf).
Here are the SIP messages capture via wireshark on the client
during one problem call. Following these SIP messages, the
wireshark trace shows only RTP packets from server
(172.16.0.245) to client (172.16.0.71) except for an occasional
RTCP packet from client to server (sample below).
Any help is appreciated. The uses are really beating me up to
get this fixed.
