>> I don't know where you get the number 12.

On my napkin I have:

Each SIP client maintains at a minimum:

1. SIP Publication for each own state
2. SIP Subscription for presence.winfo event
3. SIP Subscription for presence  event for rls
4. SIP Subscription for xcap-diff event
5. HTTP Connection for XCAP document rls-services
6. HTTP Connection for XCAP document resource-lists
7. HTTP Connection for XCAP document pres-rules
8. HTTP Connection for XCAP document pres-content icon document
9. HTTP Connection for retrieval of the icon published by the remote contact

Two clients then need in total at least eighteen dialogs to maintain end-to-end presence signaling.

I was wrong, there are not 12 but 18 dialogs.
