Description:	(About 100+ calls simultaneously) When mixmonitor is active and some calls hangup(stopmixmonitor), voice distortion occurs on IVR playbacks for other active calls. There is no RTP lost packet, only distorted sound. If i disable mixmonitor app or use Asterisk 11 Playbacks are fine in this situation.

In addition a packet capture with RTP audio demonstrating a call where the audio is distorted at some point during the call. Please make sure the packet capture correlates with the debug log.  Thanks!

Do you have a way to reproduce the issue in small scale, with only a few calls? Or can you only reproduce the issue with your production load of calls?
