Looks like it's this problem: http://trac.pjsip.org/repos/wiki/Getting-Started/iPhone#interruption

Problem with interruption (by a phone call or an alarm), headset plug/unplug, or Bluetooth input

For devices running iOS 4.0 or later, you need to enable your application to respond to remote-control events. This allows PJSIP to properly receive and process the above events. You can do this by adding the following code in your application:

[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

For more details, please refer to Apple's doc on ​Remote Control of Multimedia.

I have already tried this but it did not work. I get error 14:52:14.774 ERROR: [0x4927000] AVAudioSessionPortImpl.mm:50: ValidateRequiredFields: Unknown selected data source for Port iPhone Microphone (type: MicrophoneBuiltIn)

Not sure if there is a good way to handle this in GOSSIP. PJSIP probably has some some hook I can plug into, then I can pause or background the calls. Needs further research (aka time).

Feel free to PR if anyone manages to figure this out : )
