the problem is that you are using webrtc sipml5 and we don't have support for webrtc sdp's yet. It will work once we are done adding support. On Tue, Aug 28, 2012 at 7:39 AM, Antonio <asilva@wirelessmundi.com> wrote:
** Hi all,
I'm having a problem to make calls, when the destination answer, the calls is hangup with incompatible destination.
Debugging, i could see that is because fs drops the call, because it doesn't support ZRTP.
So, is it normal that freeswitch hangs up the call when in the remote party send in the sdp "a=crypto:1 ... " ?
Should it ignore and try to established the call using the supported methods in the sdp? Like for video calls, if the remote send video codecs, if we do not have them we don't hangup the call... just make a simple audio call...
For incoming calls there is no problem.
