Hm, thanks for the clarification, this confirms what I suspected.

Can anyone suggest an alternative application I could sensibly use alongside 
Asterisk in a production environment to achieve this (I'm specifically looking 
for a way to maintain presence information for a Busy Lamp Field, and to get 
notifications about Voicemail events).

I'm aware of both SIPp https://github.com/SIPp/sipp and SipSak 
https://github.com/nils-ohlmeier/sipsak, however these are (to me at least) 
testing scenario tools designed for "short term" use to place and receive 
calls, rather than maintaining long-term subscriptions to SIP accounts, 
waiting for notifications of events, so I'm somewhat wary about considering 
them for use in a production environment (by which I mean I'm looking for 
something which can subscribe to a few tens of SIP accounts (across several 
servers) and get the event notifications for those accounts, over a period of 
days and weeks, and pass them to my display application in almost any 
reasonable form).


Any ideas out there?


Thanks,


Antony.
