asterisk users - Jan 2006 - Heavy Static on incoming calls

Hello All,
 
We are experiencing "heavy static" on our analog lines when dialing
into
our asterisk server.  We have a Digium TDM04B with 4 FXO modules.  Two
of the modules are connected to our analog lines from our local telco.
 
This doesn't happen with every call.  It's definitely a random issue.
 
Thanks in advance,
 

Jason Adams

Sounds like an IRQ sharing issue with the card.  This comes up alot. 
Do a lspci -vb and find the card and check if the IRQ is being shared
with another device in your system.

I checked and the digium card was sharing with the onboard usb
controller.  I disabled the USB in the BIOS and now it's on it's own
IRQ.  The sound quality already sounds better.  Thanks for the help!!
