Lower volume from AVPlayer after I answer a call

[ash.x.ash@xxxxxxxxxxx (Ashraf Jaddo)]

Hello all,
I am using AVAudioPlayer to play a sound in a loop when i get an incoming call from pjsip. I noticed that when I deploy a fresh copy of my code to a device i hear the volume high and clear every time i call the device.. but at the moment i answer a call and let PJSIP does it thing to connect the phone speaker ...etc, i noticed that every time i call after this point the volume from AVAudioPlayer goes down, to summarize:
- Start the App for the first time.- Call the device.- My app will ring and volume will be ok.- Do not answer and hangup.- Try to call again.- My app will ring and volume will be ok.- Do not answer again and hangup.- If i kept doing this i will see no problem and my AVAudioPlayer will play my ring tone loud and clear.- Now call the device again and answer.- The call will be connected with no problem. hangup now.- Try to call at this point. the AVAudioPlayer will play the sound really low at this point !!
any ideas?? I think PJSIP is doing something when i connect a call.. the way i am starting PJSIP is similar to the PJSUA examples and i am defaulting most of the configs..
I am using this code to play the ring tone in my ViewController that i show when i get an incoming call notification from PJSIP:










        NSURL* musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
                                                   pathForResource:@"ring"
                                                   ofType:@"caf"
                                                   inDirectory:@"SystemSounds"]];








        audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];  // audioPlayer is defined in my view controller *.h 
        audioPlayer.numberOfLoops = -1;
        audioPlayer.volume = 1.0;    
        
        [audioPlayer play];    
        
Thanks,,,AsH
