Trigger re-INVITE with different SDP during a call
Hi, Is there a way to trigger a SIP re-INVITE for a channel that has already been answered, and to make FreeSwitch offer a certain list of codecs to the endpoint? Let's assume the call is answered with PCMA/PCMU, then the user enters an IVR, now we know that he's going to join a conference. For the conference, I might want to enable G.722 and H.264 video (which should not generally be enabled for all incoming calls). I found stuff about codec-related channel variables, but no 'trigger' to tell FS to make a codec re-negotiation. Greetings, Roland
Not sure but i think FS can't initiate re-invite, however if caller (or callee) initiate a re-invite then FS responds accordingly, including codec renegotiation. Thank you. 2012/1/23 Roland Hänel <roland@haenel.me>

Hi, Try setting bypass_media_after_bridge=true with <param name="inbound-codec-negotiation" value="greedy"/> in sofia profile and then pass absolute_codec_string before bridge on the new leg like <action application="export" data="nolocal:absolute_codec_string=PCMA,PCMU"/> bypass_media_after_bridge=true is a bit similar to canreinvite of asterisk Regards, Zohair Raza On Mon, Jan 23, 2012 at 1:59 PM, Muhammad Shahzad < shaheryarkh@googlemail.com> wrote:

Hi, All these solutions only work for the specific case that the re-INVITE is done to match an outgoing call (bridge / transfer). What I'm looking for is a way to initiate a re-negotiation, not necessarily because the call is going to be bridged. For example to change the codec prior to entering a conference.

Hey, I'm not very sure about this. I pretty much guess that the kind of re-negotiation trigger must always come from UAC from either end for FS to relay it to other end, otherwise FS is a server and I doubt this may not get "triggered" from server itself. Anyways, that was just my humble opinion some other SIP+FreeSwitch guru could guide you better. Regards, Sammy 2012/1/23 Roland Hänel <roland@haenel.me>
