    I had this issue before and was resolved when I loaded previous version. I loaded new version (2434) and I got it again. Here is what happens.

    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. I will place my firewall / NAT settings but this has not been changed. One thing I notice is that my STUN used to resolve to address:5060 now its a number in the 10000's. 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.

    edit the extension and try to set the flag "is external" on the advanced option tab.
