[SIPForum-discussion] A and B with G.711

[Vivek Batra]

In confirm dialog, you can negotiate SDP using Re-INVITE however you can
again negotiate the SDP in early dialog using UPDATE.

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
