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?
