<DIV><SPAN class=634270522-07042005><FONT face=Arial size=2>I'm trying to use an
FXO card to connect to a PBX (Toshiba DK-424). Currently I'm testing with
an x100p, but eventually I'll be using TDM400s with FXO & FXS modules.
The Asterisk box is not detecting disconnect from the Toshiba, which is not
surprising, since the Toshiba is not capable of providing disconnect
supervision. What the Toshiba can do, is provide an "A" tone upon
connection, and a "D" tone upon disconnect.</FONT></SPAN></DIV>

<DIV><SPAN class=634270522-07042005><FONT face=Arial size=2>I need to find a way
for Asterisk to detect the DTMF "D" tone, and use that to determine that the PBX
has disconnected.</FONT></SPAN></DIV>

<DIV><SPAN class=634270522-07042005><FONT face=Arial size=2>Is there any way to
do this? Will this require modifying code, or is there some way to tell
the Zaptel driver to look for the "D" tone?</FONT></SPAN></DIV>
