Hi @colinyip

Sorry for not responding back to you sooner. Thanks for providing the crash and it seems like there is some custom audio device implementation in your application.

• Is it possible to tell (from the application/SDK log) what exactly is the action that the application was performing when the crash happened?
• Can you share some implementation details around the audio device in your application?
• It would be great if you can enable the logging for the WebRTC module by

  [TwilioVoice setLogLevel:TVOLogLevelTrace module:TVOLogModuleWebRTC];

Thanks, -bobie

Thanks, -bobie
