I tried to use local notification if there is a incoming call when my app was in background mode. After sending notification, Xcode shows

ERROR: [0x1a11f9000] >aurioc> 807: failed: '!pla' (enable 2, outf< 2 ch, 44100 Hz, Float32, non-inter> inf< 2 ch, 0 Hz, Float32, non-inter>) Failed to initialize graph ('!pla').

If I continue to click this notification, my app would be restart. I don't know whether problem happened in this progress from background to foreground or in setting VOIP.

  • I don't have working experience in VOIP. To receive incoming voip call, apple introduces PUSHKIT Framework, which will handle push notification from server. Just i like to inform, this could be the better option. – RJV Kumar Jan 02 '16 at 06:02
