[asterisk-users] Problems with dual FXO/FXS cards - noise
Hello all,
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.
What I tried:
* Dual Power Supply, one just for PCI Cards - no success
* fxotune -i 5 ; fxotune -s
* Using without any echo canceller, OSLEC, mg2, and every extension and
pstn, just on pstn, without success
* Compiled kernel (I am using elastix)
* Tried getting out on 6 differents pstn (4 from one provider, 1 from
another, and 1 using a external gsm gateway) - no success
* Removed one card and use just one - without a difference
* Asterisk -p
* Renice asterisk to -10
* Messed with pci latency (increased the pci latency for the pci cards, but
no improvements)
Even if I offhook my phone, the dialtone has noises!
CPU: Celeron 450 @ 2.20GHz
2 GB RAM
SATA Harddisk
WHAT CAN I DO? Thanks for any help!
