A1200P busy detection problem

Dear developers!

I've got trouble detecting busy tones on A1200P card. Actually, it doesn't work. My zapata.conf is the following:

context=incoming
usecallerid=no
hidecallerid=no
immediate=no
busydetect=yes
busycount=3
callprogress=no
callerid=gorod <1>
echocancel=yes
echocancelwhenbridged=yes
echotraining=400
context=incoming
group=1
channel => 1-2

I am running Asterisk-1.2.9.1, libpri 1.2.3, zapata 1.0.1, zaptel 1.2.6, vanilla linux kernel 2.6.16.18.

Any ideas?

Thanks.

A very valuable remark: busy detection DOES work with A100P (single FXO) card.

callprogress=no

you should change this line to
callprogress=yes

can you try in your zapata.conf with:

busydetect=yes
busycount=6
