<p><font face="Arial, Helvetica">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.</font></p>

<p><font face="Arial, Helvetica">SIP trace is located at <a href="https://www.4shared.com/file/wIVrkOtnei/SIP.html">https://www.4shared.com/file/wIVrkOtnei/SIP.html</a></font></p>
<p><br></p>
<p><font face="Arial, Helvetica">From the SIP responses, it appears that the code is performing correctly. Not certain what to try next. </font></p>
<p><font face="Arial, Helvetica"><br></font></p>
<p><font face="Arial, Helvetica">Also, the RTP Proxy server was rebooted.</font></p>
<p><font face="Arial, Helvetica"><br></font></p>
<p><font face="Arial, Helvetica">Any suggestions?</font></p>
