i had this problem with a gateway witch was configured from 1000 to 3000 and some time he was using ports above 2000 and result was one way voice rtp port range is where asterisk expect audio, you should not use ports below 10000 because they are in use of other services like 5060 for sip. <br>

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.<br>
<br>
But, I've set my range to 5000 - 40000. I'll find out tomorrow if it makes any difference.<br>
<br>
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.<br>

have you changed port range? if no then<br>
your client sending rtp to a port higher then configured in rtp port<br>
range and asterisk ignore that port.<br>
try to change rtpend=30000 or if there is option in<br>

let me know if this solve you problem.<br>

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