Remote Phone - No Audio - Monitor Trace 1

[OldSchool70]

We have a customer with IPO Preferred Edition on Rls. 9.1 They have a handful of Remote 9608 and 9611 phones deployed and working fine. They tried to add another remote phone yesterday. The phone registers but there is no audio (not even dial tone). I assume if the phone is registering then the remote user's ISP is allowing traffic on Ports 1719 and 1720. My experience with no audio issues has been that the RTP (UDP) ports are blocked or are not within the range that the IPO is using and the customer's firewall is allowing. How do I determine which RTP ports the remote is using? Will monitor show that?

On monitor you can open the RTP status window

IP Office remote service
Fixed price SIP trunk configuration
CLI based call blocking
SCN fallback over PSTN

Changed the 802.1Q setting to off and calls started working.
