Hi all related guys, I am using the Siphon with PJSIP2.0 on the iOS7.0. However my volume level is degraded after making a VoIP call. Note: This bug ONLY happens on iOS7.0. What I have done: 1. Downloaded the Siphon which using the PJSIP2.0. 2. Added a view to play an audio file with the class "AVAudioPlayer" of Apple 3. Played the audio file and its volume was normal. 4. Made a VoIP call out. After the call is connected for several seconds, end the call. 5. Tried to play the same audio file. However the volume is much degraded. And I checked the system volume level which was the same as before. I don't know why this happens. And I just find that the audio mode is changed after making a VoIP call (from default to voiceChat). So I tried to fix it, but failed. If it's a bug, is there anybody who can fix it ? Awaiting your response. Thanks a lot! ------------------ Regards, Albert -------------- next part -------------- An HTML attachment was scrubbed...
