dahdi busy detect does not work

Hi,

I've installed AsteriskNOW with Asterisk version 1.6.2.23 with FreePBX version 2.10.1.4. I'm using dahdi with OpenVox A1200P card for 4 analog lines (I have past successful experience with that).

Everything works fine: I can dial out and in. Seven internal extensions are connected and fully operational. However, there is one major problem and that is the "busy" signal is not being detected! It causes, of course, many problems (trunks stay open, rendering the system with no free lines, voicemails are becoming enormous, etc.)

As I have experience with that, I've set in chan_dahdi.conf:
busydetect=yes
busycount=3

but, it looks like the system ignores this.

I've restarted the services, then rebooted the entire server, then disabled the Dahdi config module in FreePBX. Nothing helped!

Can anyone help me with that?

Hi,
Pls try to enable following parameters in chan_dahdi.conf:
answeronpolarityswitch=yes
hanguponpolarityswitch=yes
After that, restart asterisk and try again.
If still not work, send me remote access, I will check it for you.
