Ok, so from the app I am able to see the other extensions and their status, so it can definitely talk to the PBX. I can also call out with no issue. The only issue is when the iPhone has been idle for a minute or so (screen off in the users pocket for example) and a call comes in. The iPhone will ring, and you can answer the call and talk for about 10-15 seconds and everything seems fine, but then the call drops. If you have the Vodia app open already and a call comes in, you can pickup the call and it works fine. It will not drop. Also, every time the iPhone is idle and receives a call through the Vodia app, I get an email from the server saying this:
"Source address for sip:2715@max-solutions has changed from tls:126.96.36.199:62865 to tls:188.8.131.52:62869"
Any idea what may be happening? Is anybody else having this same issue? I'm only having issues with the iPhone version of the app which unfortunately is what most of my customers have. Users with Android phones are not having issues with the app.
