Summary:                    Add Basic Support For RFC 4662 (Subscribe to lists)
Description: 
Preamble to 4662

---
   This document presents an extension to the Session Initiation
   Protocol (SIP)-Specific Event Notification mechanism for subscribing
   to a homogeneous list of resources.  Instead of sending a SUBSCRIBE
   for each resource individually, the subscriber can subscribe to an
   entire list and then receive notifications when the state of any of
   the resources in the list changes.
---

the polycom 601 BLF uses this extension to populate and manage its BLF i
cant see why not to support it in asterisk ??

please see the packet trace (supplied by polycom thx this is invaluable
...) a comparison (summary of progress so far) and a patch against 1.4.9
(obviously this is for 1.6 ...)

ok please ignore the changes to support snom directed pickup ... 

the idea is now to sip_alloc a subscription for every line and add append
the dialog-info to the message ...

is there a better way ...  ??

if a notify is required for a single line do not send a "fullstate" ...

is there any requirement for this ??? 

this is realy bare bones and not even close to functional some input as to
wether this is heading on the right track will be appreciated.
