Life got in the way, and I was unable to deal with this issue for a while.
I took firebird's advice and swapped systems, the problem stayed the same. Both systems are now exhibiting this issue.
I spoke with my provider (Flowroute) and this was their response:
Looking at the call we see it set up normally but during the re-invite to place the call on hold we see the media IP change to a private IP address: 192.168.1.90. When the 2nd re-invite comes to take the call off hold it still shows the private IP address for the media IP. Since the private IP address is not routable the media then fails. Please adjust the media IP to the Public IP address. We are also seeing the private IP address in the Contact and the Via headers which can also cause some issues. We recommend changing these to the headers as well.
I have not had the time to sit down and make any of these changes, but I did find a workaround to the problem. For now, In features, I've turned "Music" off and set MOH to "Silent", this appears to skip the re-invites and just hold the line silently. If anyone knows off the top of their head what settings I need to play with in order to avoid the issue described above, I'll happily test and report back, otherwise, it looks like I'll be digging through the manual and stabbing in the dark.
I'll dig into this more sometime this week, but wanted to give an update to the thread in case anyone else comes looking for this information sometime down the line.
