Hi,
If the offer and answer had both G.711 and G.729 where G.711 was the first
one in the m line it means that both can be used and G.711 is the preferred,
you can switch the codecs without any signaling.

Greetings:
I believe a reINVITE should be used since the change will be during an
established dialog. RFC 3261 should provide guidance.

Hi all
Suppose A and B are in conversation stage with g.711 codec.
A want to change his codec with g.729 ( any other also) which B
supports. In this
Scenario how A has to communicate with B in Sip. Whether UPDATE can be
used? If yes how?
Regards,
Jyothi
