Codec Negotiation Error Lync/UCMA -> external provider
Hi there, I'm a newbee, but I've been reading everything I can and I can't find anything that assists with this. I have a UCMA app that is internal that communicates on the internal sip port (set to 5042) and it bridges with dialplan to the external sip trunk (trying 2, one of which is siproutes). If I enable proxy, the call rings out and I get dead air on the other side, but it won't ever properly establish the call in the UCMA app because of some issue with codecs from what I can tell. Obviously I don't want to use proxy mode, what I really want to do is use it straight up and have FS do the transcoding etc. The problem is that once I do this I get a Codec Negotiation error and I can't figure out why. Anyone have any ideas as to why it's freaking out like this? (log below) Thanks! 2013-05-21 12:09:41.570884 [DEBUG] sofia_glue.c:1219 Local SDP: v=0 o=FreeSWITCH 1369129003 1369129004 IN IP4 10.8.0.158 s=FreeSWITCH c=IN IP4 10.8.0.158 t=0 0 m=audio 23578

Looks like a device is misbehaving and violating RFC3711. Fortunately you can explicitly allow this behavior: http://wiki.freeswitch.org/wiki/NDLB#NDLB-allow-crypto-in-avp Let us know if that works. -MC On Tue, May 21, 2013 at 9:11 AM, JohnGalt1717 <jrlh@outlook.com> wrote:
