Hi Michael, thanks for your reply! Yes from debugging I saw that the endInterruption is not called always: ( And in fact this is my issue?. How can I know from pjsip that the interruption begun? There is no callback from pjsip about this state? and how can I tell to pjsip to recover audio?

Extra setActive:YES calls are for audioSession not harmful.

While pjsip is correctly recovering audio if interrupted by a GSM Call, it does not recover correctly if the VoIP call is interrupted by a multimedia file, let's say youtube video for example. The problem is that (from the log) I can see that pjsip correctly receives the BeginInterruption notification but does not receive the EndInterruption. Is this a known issue? Or there is something I have to implement in my application in order to manage this scenario? In addition, how can the app being notified by pjsip of the interruption in order to put on hold the VoIP call? Please note that the GSM call interruption is correctly handled, so I already put in my app the following lines of code: - (BOOL) canBecomeFirstResponder { return YES; } -(void) viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; [self becomeFirstResponder]; } Thanks a lot in advance!
