Thanks Ken, I emended the documentation with your explanation: https://freeswitch.org/confluence/display/FREESWITCH/Codec+Negotiation#Codec... On Fri, Jul 15, 2016 at 12:14 AM, Ken Rice <krice@freeswitch.org> wrote:
This new variable is required with 1.6 and later due to webrtc support and the ever growing SDP when SIP over UDP is involved.
SDPs have now reached the point where it is becoming harder and harder to translate from WebRTC -> SIP and keep the original SDP due to the shear size of the SDP. With SIP over UDP, when packet fragmentation happens, it destroys the SIP packet as UDP does not auto-reassemble the fragments… this happens once your sip packets exceed MTU… the only fix is small packets. That means compact headers, eliminating extra headers, or just don’t use such a big SDP by eliminating CODECs you don’t need.
The affect with FS is if you don’t have media_mix_inbound_outbound_codecs set to true, only codecs offered to FS on the A leg are passed to the B leg, this reduces the size of the SDP and has the side effect of greatly reducing the amount of transcoding.

Yeah, i put media_mix_inbound_outbound_codecs =true in vars.xml and it's working...
I was using FS 1.4 and 1.5, this was working fine, no problem.
When i clone 1.7, this happen...
Now this is fine, thanks a lot.

He’s looking for media_mix_inbound_outbound_codecs the incoming codec from the inbound GSMopen channel is L16… so that gets sent out because he doesn’t have media_mix_inbound_outbound_codecs set to true… see https://freeswitch.org/confluence/display/FREESWITCH/Codec+Negotiation

Yes, this is because of codecs.
Have you edited vars.xml ?
You are sending out a nonexisting codec (L16)...
Please put vars.xml and all codec related configurations back to their original value.
No need to touch them at all for gsmopen to work.

Hi, I'm trying to make a call between GSMOpen (GSM) and a user (or a group, it's the same).
But I receive a 488 INCOMPATIBLE_DESTINATION
I'm thinking this is because the codec negotiation.

Please, someone know how to solve this?
