asterisk users - Mar 2004 - X100P Tone-based Supervisory Disconnect ?

Hello all,
    Through the previous two weeks I have been working on my first 
asterisk installation. So far all my doubts and problems were aswered by 
the list history or on-line documentation. I have a two SIP softphones + 
external analog line working fine. However, I just came across a 
documented problem that as far as I can tell there is no good answer: 
the X100P FXOdoes not  hung up  when  the remote end disconnects. I have 
a X100P connected to an extension of my company PBX. When I get an 
incoming call, it stays up even when the caller disconnects and I have 
to use a soft hungup.
     I  have already tried all signalling methods (ks, gs, ls) with no 
luck. Searching  on the web I found a good description of the problem on 
the Cisco site: 
http://www.cisco.com/warp/public/788/signalling/fxo_disconnect.html
    There is a method of hang up detection there called Tone-based 
Supervisory Disconnect. It seems to me that it would fix my problems, 
because my company PBX does send some fast tones when the line gets 
disconnected by the remote end.
    Does asterisk have this feature? How can I turn it on?

    Thanks a lot,
    Gelson

The X100P hangup problem is indeed pervasive.  My current
testbed has the X100P connecting to an FXS breakout of a
dual ISDN channel box.  Indeed, remote hangup is NOT
detected.  When I switched it to a POTS line, all the sudden
it seemed to work OK.  This is a serious limitation in some
scenarios however.  There was a response a few days ago
about recompiling [*] with some different options in the
driver (had to do with the same problem on a UK line).  When
this gets resolved, this would make for another fine wiki
addition.
Cheers,
WW

Take responsibility for your ISDN equipment not providing what you need.
Either it needs to provide you with disconnect supervision or it needs
to play a set of tones that are identifiable and specified for the audio
disconnect to work.

    Does it mean * supports  tome based disconnect?  How can I turn it 
ok?  That  what my original question (i?m the original poster).

Try with:

busydetect=yes
busycount=7

in zapata.conf
