Hello all,<div><br>Here is my scenario that I would like to ask for help. I have a dedicated machine, with two PCI cards (a x1600p with 6 FXO for PSTN and 6 FXS for extensions and a x800p with 8 more extensions). I have a strange background noise, and sometimes get robotic voice, even on IVR. My credit cards machines and fax won´t work either (well, credit cards just sometimes), because I believe that the noise is interfering with the communication.<br>
<br>What I tried:</div><div><br></div><div>* Dual Power Supply, one just for PCI Cards - no success</div><div>* fxotune -i 5 ; fxotune -s</div><div>* Using without any echo canceller, OSLEC, mg2, and every extension and pstn, just on pstn, without success</div>
<div>* Compiled kernel (I am using elastix)</div><div>* Tried getting out on 6 differents pstn (4 from one provider, 1 from another, and 1 using a external gsm gateway) - no success</div><div>* Removed one card and use just one - without a difference</div>
<div>* Asterisk -p</div><div>* Renice asterisk to -10</div><div>* Messed with pci latency (increased the pci latency for the pci cards, but no improvements)</div><div><br>Even if I offhook my phone, the dialtone has noises!</div>
