Hi, Update is a target refresh method used to issue offer predominantly during early dialogs. This refresh can be used to modify both the "c" IP and "m" port parameter. Along with that you can also add other parameters like you want to add video along with audio or you want to change codec etc.

When we send an UPDATE method, it is basically to update the parameters of a session and has no impact on a dialog. So, my doubt is whether the connection(c) and media (m) of SDP body in UPADTE will be different from that of the INVITE? means the IP address in "c" and the port in "m" will be different from that of INVITE or not. Please clarify me in this regard. Thanks & Regards, Ashutosh Pattanaik. SPAN Systems Corporation, Bangalore.
