I enabled echo cancelation.
i Tested with only two ISDN devices - and B200P ISDN phone and Asterisk.
also through the ups, the light turns on B200P get bad sound in the headset, as I described earlier. I recorded the sound.

I heard your audio file, it seems to be affected by some devices around your environments.

Would you mind providing ssh info to me? Let me have a check for you.

i discovered next situation:
i call and speak to isdn phone when is asterisk down. voice is normal.
when driver is loaded is voice bad, when loads echo cancelation is voice normal again.
then i call again and voice is bad.

I think this is some sethings problem.
I would be very grateful for assistance.

Add a debug parameter when loading wcb4xxp, like this: modprobe wcb4xxp debug=1.

and enable the debug parameter in file /etc/asterisk/logger.conf, start asterisk by `asterisk -vvvgc -d` instead of `asterisk -vvgc`.

Meanwhile, set the verbose to a higher value.

Make a phone call and post the `problem` log and dmesg info here. We can not help you more if you can't provider debug info for us.

I have disabled the services including SELinux, iptables and bluetooth. Could you please restart your system and see if there is improvement?
