[reSIProcate] RFC Question...

[John Draper <lists@xxxxxxxxxxxxxxxx>]

Hi,

I have a question about the interpretation of the RFC 3261.  Cam someone 
explain a few
things for me?  It is part of my feeble effort to understand what A 
dialog is,
and how it relates to requests, when they are created, and what they 
contain.

The RFC says....

12.2.1.1 Generating the Request   

    A request within a dialog is constructed by using many of the   
    components of the state stored as part of the dialog.

Ok - what do they mean by a request within a dialog?   Does this mean
I instantiate a "dialog" object at the same time I send the INVITE?

and a request that is NOT in the dialog,  would be like the REGISTER?
is that right?

The RFC goes on to say.... "using many of the components of the state".
What is the meaning of the word "components" in this context?  and
it states that the state is stored as part of the dialog.  If that's the
case, then why is it part of SipSession?  Do all dialogs have SipSessions?

But the word "components" really confuses me when used in this context.

Thanx
John
