It's probably not the smartest move for the phone to renegotiate codecs at this point. But I think FS should be able to deal with it (without simply falling back to transcoding). I've tried if putting "disable-transcoding" into the profiles changes anything, but it didn't. "renegotiate-codec-on-hold" and "renegotiate-codec-on-reinvite" are gone since FS 1.6.10 so I can't try those. I read something about "indicate_hold" which probably means that FS will send a reINVITE on the other leg, so I might try that.
I thought about it some more and came to the conclusion that for a B2BUA it does seem legit to accept the first codec in the reINVTIE's offer and use transcoding to make the bridge work. It's not what I would like to happen, but that's a different story :D I also found a posting from 2011 which mentions this behavior: http://lists.freeswitch.org/pipermail/freeswitch-users/2011-December/078228.... Anyway, "case closed". Regards, Sebastian
