I'm not sure what the beeping is, other than possibly call-waiting. As for the echo, I found the MARK3 echo cancellation to work best for me, but I've only tested a few of the available options.

Subject: [Asterisk-bsd] Line problems with wcfxo driver


I've been having trouble with a  X100P card.

I'm running the latest svn trunk, on FBSD 6.1 with * 1.2.9

Problems are, I hear beeping periodically on the line, and I'm
fighting the ever present echo issue.

I've played with the rxgain and txgain, and I can get the =>PSTN
volume good, but the audio <=PSTN  is still noisy and the quick
beeps are annoying.

Is it an impedance issue?  I've tried all variations of gain from +4
to -3, and can get the volume satisfactory, with minimal echo, but
it's just not as clear as an analog phone hooked to it.

Could it be a taps issue?  I saw in the kernel modules it has either
64 or 128 taps as default.

Any help or pointers would be appreciated.
