IP Office v11 drops Flowroute SIP audio after 15 minutes

[ZL_OR]

After working with 2 different Avaya Support Companies we still have this issue. On Incoming and Outgoing calls the audio for both ways gets lost at almost exactly 15 minutes, it doesn't matter what kind of number we are calling. This happens 99 percent of the time, the few times it hasn't happened it drops at 30 minutes. Flowroute suggests that its an RTP issue which we have changed those settings around without success. We have port forwarding to the IP office. I have screenshotted all of the relevant pages of the manager, unifi controller, and email from Flowroute. The route is Centurylink Fiber > Unifi USG Pro 4 > Unifi Switch > IP Office. We have 2 channels from flowroute. We primarily use J179s.

Please share your thoughts. If I missed any information please let me know. I have spent many hours searching the web with no luck.

Thanks,

Have you tried changing the refresh method to Update?

Are you able to take a wireshark trace (or something similar) to examine the SIP traffic? Does Flowroute send Update or Re-Invite periodically?

The question is have you done a Monitor trace yet?

It's the first thing you do to troubleshoot most IP Office issues.

This is a firewall issue. There’s only so much you can do on IP Office to compensate for it. At some point (now), you need to undo all the workarounds and put in another firewall, even if just to prove the theory.

We use Sonicwall, but have a few sites with Fortinet.

Here is a link to setup Flowroute with a Sonicwall:
