Re: [Asterisk-java-devel] Retrieve list of all live extensions...

[Yves A. <yv...@gm...>]

Hi,

afaik, the feature you´re looking for is not that much "wishful 
thinking"... it is not impossible, but the amount of work you have to do 
also
depends on the asterisk-version you are using.
As i mentioned... depending on the asterisk-version, you could use: (*)

1st) "SIP subscriptions" this feature is known as BLF (Busy Line 
Feature) or Presence / HINTs.
2nd) since asterisk 1.6 via DEVSTATE (afaik there is a backport for 
asterisk 1.4)
3rd) Implement it yourself using listeners for peer-, extension- and 
channelevents..

and... there may be other ways that I am not aware right now....

(*)
try to google for more information about the listed possibilities if one 
of them is of interest for you.
If you're encountering problems in configuring one of the mentioned 
features, you could also mail the asterik-users
mailing list for help as this is going to be out of focus of the 
asterisk-java mailing list.
