[SIPForum-discussion] Query on Update method

[mehmet]

Hi,

As far as I know UPDATE dos not create new transaction.In some flows it is
not needed for new transactions for a new offer, so UPDATE is used instead
of re-invite, to avoid creating a new transaction.

If you want you can find more details about UPDATE method within this RFC :

http://www.rfc-editor.org/rfc/rfc3311.txt

And call flows for UPDATE method :

Regards.
