Summary:                    [patch] Presence subscription on Cisco SIP phone
needs special Cisco-styled XML
Description: 
Cisco phones appear to be unable to parse the existing PIDF XML being
generated by Asterisk for presence notification.  I've attached a patch
which produces well-formed (but incomplete) XML which will satisfy a Cisco
phone.  The patch as supplied will successfully render a "busy"
subscription, but does not send a subsequent "available" notification, so
presence detection only half works currently.

I suspect the next step might be to watch some CallManager SIP traffic to
identify precisely what XML tags the phone is expecting in order to
properly parse an available subscription, but I'm not in a position to do
that.  I'll continue to work with this, though, and perhaps may be able to
stumble upon the precise data the Cisco phone is looking for.
