Hi, Pat!
Can you send over the logs from rtpproxy? Perhaps I can figure out why
rtpproxy is not sending RTP to the new port.
Best regards,
Răzvan

We have a situation where a fax comes in, all of the negotiation looks
good (ports are translated like they are supposed to be), and the
interface with RTP Proxy looks correct (at least to me). But what
happens is that after the Re-INVITE for T38, the RTP Proxy continues to
sent the RTP to the customer's old port. In the example below, RTP
Proxy sends the RTP to the customer on port 7186 AFTER the Re-INVITE
with the new port.
SIP trace is located at https://www.4shared.com/file/wIVrkOtnei/SIP.html
From the SIP responses, it appears that the code is performing
correctly. Not certain what to try next.
Also, the RTP Proxy server was rebooted.
Any suggestions?
Thanks in advance,
Pat
