in bypass media, we pass along the sdp the other side sends.  If they are sending the wrong address, we will happily send that along.  If the other end can't figure it out with its own nat fixing, it won't work.

Hi all,

I have an installation with several phones (yealink) behind NAT and freeswitch with aggressive-nat-detection=true in internal SIP Profile.
In dialplan I set bypass_media_after_bridge in order to eliminate on-way audio problems (and use less bandwidth), but I'm encountering a strange issue.
When I call two extensions, sometimes freeswitch bypass the media between them (so the SDP sent by freeswitch have the private IP) and sometimes freeswitch send the SDP with the NAT IP (in this case there is no audio).

What could be the problem?
Is this a bug or my misconfiguration?
