Hi all, This is still an ongoing issue here. Audio is 2 way for half a second before only the callee can hear the caller. If the callee puts the call on hold and resumes, the video drops but 2 way audio works. Any help would be much appreciated. Thanks! On Jun 19, 2013, at 12:18 PM, Emrah <lists@kavun.ch> wrote:

Hi guys,

Has anything changed recently on NAT traversal helpers? I have Polycom phones that used to work with inherit_codec=true, both for voice and video. After a make current, the video works consistently and the voice is either one way or inexistent. When it's one way, the caller does not hear the remote party. This seems to be related to Polycom phones only. Trying to use early media for a forced codec negotiation does not help.

Please let me know if you have any idea or how to get more data to further troubleshoot this issue.

Thanks!
