> Hi,
>
> Can someone help me figure out the problem i am hitting.
>
> Im trying to upgrade call from audio to audio + video (opus 48k and vp8-
> but this one is only in passtrough mode).
>
> So set up is browser (sip.js/node.js) >> kamailio wss >> freswitch (bypass
> mode bridge without answer) >> kamailio >> browser (node.js)
>
> Problem is that freeswitch receives reInvite on existing audio call with
> new sdp containing also video codecs, but directly from client so no proxy
> (kamailio) in path, and exiting invite towards kamailio for outgoing leg is
> missing video in a=group BUNDLE, so only audio and a=sendrcv is also being
> stripped (that is the difference to 1 on 1 video call).
>
> I understood that bypass mode shouldn't change/touch sdp.
> Also passtrough codec shouldn't be the problem i guess since both clients
> can decode it.
>
> Any help is appreciated.
> Thanks,
> Mirko
