Hi, We're implementing a voip-based iphone app, and I'm facing a situation where I'm not receiving the call state PJSIP_INV_STATE_DISCONNECTED event when the callee disconnects the call (on a PSTN). When I tried testing out the ipjsip sample iphone app provided in the SDK, I noticed that it receives the disconnect event properly. So, it seems like I'm missing something in my code. Comparing how the sample app does things did not yield anything that stands out from how we're using pjsip. Does anyone happen to know why PJSIP_INV_STATE_DISCONNECTED would not be triggered? I receive the other events properly, so it's very strange. Any pointers as to where to look would be appreciated.
