We implemented a busypattern=3D option for the zapata.conf that might help=
=20
you.

Test like so:  Dial into your Asterisk system via the FXO port to an=20
extension on your box.  Now hang up from the outside.  Listen to the call=
=20
on the internal extension.

If you hear a regular beep-beep tone of some sort, busypattern=3D might hel=
p=20
you.

You need to time exactly the length of the beep and the length of the=20
silence.  (To get it nice and accurate, record it, then load into=20
Audacity and measure).

Say it comes out at 750 msec of beep, 500 msec of silence.  Then adjust=20
your zapata.conf like so:

busydetect=3Dyes
callprogress=3Dno
busypattern=3D750,500
busycount=3D4
