[SIPForum-discussion] A query regarding the session and dialog in SIP

[chandan kumar anjani]

Hi,

I had a query like what is the difference b/w session and a dialog.
like a session can have multiple dialog or a dialog can have multiple
session.

As i know a dialog is identified by CALL-ID,To_tag,From_tag

and i a particular call all the three remains the same.

And abt the session , a session is termed to be established when we receive
200OK for the INVITE.


Regards
