[SIPForum-discussion] Difference between UPDATE and Re-INVITE

[prasanna c]

UPDATE need not exchange session descriptions, where as INVITE transaction always exchange the session descriptions. This makes UPDATE ideal for session timers implementation.

Subject: [SIPForum-discussion] Difference between UPDATE and Re-INVITE

Hi All,
 
Hope all of you are doing fine.
 
Here I am with a age old query.
 
Difference between UPDATE and Re-INVITE.
 
One basic difference is-----
 
Re-INVITE cant be sent before session is established.But UPDATE can be sent always.
 
Is there any other major difference?????
 
Thanks
