    Incoming calls no audio. If I place the call on hold then pick it up again the audio is there until 30 seconds when the call drops.

Also, I am getting Cant send RTP stream to

    All outgoing calls work well. I have listed below my firewall settings followed by logs of one incoming and one outgoing call for review. Thanks for the help.
