Hi,
Hola,
Many SIP phones implement list-based Notify-Subscribe mechanism with the
phone may request to be notified of status changes from a whole list of
resources.
Thanks to PJSIP inclusion in Asterisk 12, I'm wondering how a Resource
List Server could be implemented with Asterisk 12.
1. I couldn't see RFC4662 itself is implemented in PJSIP. Is this correct ?
Correct. The only thing it would implement is the mechanism to construct
the messages, which is a very minor part. The actual logic is the hard part.
2. Which architecture regarding resource lists would best match Asterisk
current and future feature set ?
A. In internal Asterisk feature ?
B. An external application which would subscribe to each individual
resource on one hand, and would serve list-based requests on the other
hand ?
C. Something else ?
I don't think anyone has really scoped this out. Previously due to
chan_sip it was just very invasive and infeasible to create such a
thing, but due to the modular design of chan_pjsip it's much closer to
reality. What it actually MEANS and what it would look like though...
requires thought.
3. Has someone already dealt with list-based Notify-Subscribes outside
Asterisk scope ? How would you then qualify this experiment ?
I've got nothin' here.
