[Asterisk-video] Re: Re: [Iaxclient-devel] Video codec negotiation in IAX

[Olle E Johansson]

The interesting part in all of this is that Asterisk is able to  
negotiate a SIP call with
multiple codecs, and change codec mid-call without re-negotation. The  
RTP stack
will just notify that we changed codec and the translators seems to  
be in place
somehow. I have no idea on the inner workings, but it works.

In that case, no re-invite is needed, since it was already negotiated.
