SIP INVITE request mapping to call object

Hi all,

I am currently working on my thesis which involves me creating a simplified
generic java API layer above SIP and parlay for easier service development.
This involves the creation of call objects similar to Java Call Control, and
Parlay.

When mapping an incoming INVITE (or incoming requests such as a NOTIFY for
presence for other similar objects), some mapping has to be performed. My
question is would you associate a call object with a request callid or
dialog? or both. So that when some routing operation is performed by the
client application using my API the correct incoming INVITE is referenced in
the underlying SIP stack when the call object is passed back to be routed or
proxied.

I am actually using SIP servlets for this implementation so SIP stack is not
correct term to use.
