<p class="MsoNormal">Hi, I'm new to the SPCE. I'm testing mr9.0 build 1 version and got problem with RTP when peering using private IP address. The topology is as below and the problem is in Scenario 4.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Debug from A shows in scenario 4, sipwise instructs party A to send RTP stream to 172.16.1.1 when A puts the call on hold and also after A resumes the call which is causing the no audio issue because A is unable to reach the private IP
address 172.16.1.1. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can someone point me to the right direction what settings I need to change to make it work please? Thanks in advance.<o:p></o:p></p>
