<p>Hello</p>
<p>Are you using a amd server?</p>
<p>Sometimes openvox doesn't work fine with amd processor</p>
<p>Regards</p>

<br>
Do either of the phone lines in question have DSL on them?<br>
<br>
If so, a ferrite core (which will block common-mode RF<br>
signals) probably won't help much, if at all. DSL is a<br>
differential-mode signal, and its frequency content starts<br>
down in the tens of kHz. Ferrite cores are usually intended<br>
to block much higher frequency interference, and won't have<br>
enough inductance to help much with DSL signals.<br>
<br>
What I would suggest, is that you get yourself a couple<br>
of DSL "microfilters"... plug them into the A400P FXO<br>
ports, and plug the lines into the filters. These sorts<br>
of filters are designed specifically to block DSL differential-<br>
mode signals from getting into analog-phone circuits, and<br>
they will also be fairly effective against other forms<br>
of low-frequency-RF noise.<br>
<br>
