asterisk users - Feb 2012 - Call Completion

Hello,

I'm trying the Call Completion system. All work fine.

I still don't undesrtand how Asterisk work.

Does Asterisk use sip signaling or other protocol to send notifications?

On the Asterisk Wiki seems that the system is based on 
draft-ietf-bliss-call-completion-04 but this draft talk about SUBSCRIBE and 
NOTIFY.

I see nothing in sip capture.

Can you help me with this question?

Thank's

Regards

If your SIP UAs (phones) don't implement that draft, then they won't 
SUBSCRIBE for call-completion events. That means you'll be using the 
'generic' call-completion agent and monitor in your sip.conf file.

Asterisk can use SUBSCRIBE/NOTIFY to handle call-completion with another 
Asterisk server if your network has such a connection, but otherwise we 
aren't aware of any SIP UAs (phones or otherwise) other than Asterisk 
that have implemented this draft.
