asterisk users - Dec 2004 - X100P and Mitel SX-2000 Light

I've configured an analog/single line off my mitel sx-2000 to a x100p
card in my *, however when the remote caller drops the line I get a
dialtone back from my pbx and the x100p doesn't detect the end of the
call.  Any way I can tell * to drop?  I've tried call progress but it
doesn't seem to work...

The Mitel is not dropping the line voltage to indicate to the X100P that 
the call has ended.  If there's a way to enable this on the PBX then do 
so.  It's commonly called Disconnect Supervision.  MANY PBXs simply 
don't support disconnect supervision on their FXS ports.   You can play 
with the busydetect and busycount options in /etc/asterisk/zapata.conf 
to see if that helps.

The way I usually link Asterisk with a legacy PBX is to use the TDM400P 
card with FXS modules.  Then just plug Asterisk into the CO/Trunk ports 
on the PBX.  Asterisk does not provide Disconnect Supervision on the FXS 
ports either but the PBXs I've worked with seem to detect the congestion 
tone Asterisk provides as a disconnect and it works pretty well.
