asterisk users - Jan 2012 - SLA for DAHDI FXO - Emulating Key System Functionality

Greetings-

I currently have a customer that *requires* key-system functionality in an
Asterisk PBX. On a SIP phone, the BLF keys need to show the current state of the
analog lines attached to the system (DAHDI FXO). By pressing one of these keys
(for line 1 for example), the dialed number needs to be dialed out the correct
port. Also, when that line is busy, the phone BLF key for that line needs to
reflect the status.

I've been reading about SLATrunk but it doesn't seem quite what I'm
looking for. Also, I'm looking at using Hints to supply such information,
but I'm not sure exactly how it should look.

Has anyone done this before, and if so, how did you implement it? My target is
to use Asterisk 1.8 but another version would suffice.

Looking forward to your comments!

The SLA functionality is exactly what you are looking for.
