Summary:                    [patch] 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 ...)

putnopvut:

Yes, this RFC assumes that the RLS (Resource List Server) is aware of the
composition of list URIs. How the list URI is populated in the server is
out-of-band of SIP. 

The behavior of the phone doesn't change much (it'll still contain local
buddy list as before). It'll receive NOTIFYs like before (even though they
can now be optimized to contain multipart MIME to deliver states of several
buddies in one message) and process them like before.
