[Kamailio-Devel] presence/presence_mwi question

[Klaus Darilion]

Hi!

I try to understand how presence extensions works, thus I reviewed the 
presence_mwi module.

What is the exact purpose? From my understanding it is:
- receive SUBSCRIBEs for MWI and maintain the subscriptions
- receive PUBLISH requests and forward the body in NOTIFYs to the 
subscribed user.

Is this correct? Then I wonder why there is no code for dealing with the 
subscriptions - is this all done automatically by the presence module?

What If you want to write a "presence_dialoginfo" module which handles 
dialog-info (not draft-anil-sipping-bla-03.txt but RFC 4235). The module 
could add the "dialog" event to presence module (which should handle 
SUBSCRIBE/NOTIFY) and register callbacks from dialog module to get the 
dialog info. But how can I trigger sending new NOTIFYs with the 
corresponding body from within the presenece_dialoginfo module? Can this 
be done directly or do I have to use pua module to loop a PUBLISH to myself?
