[asterisk-users] Really bad phone line.. possible causes?

I was wondering if those more familiar with PSTN->Asterisk installs
could take a listen to this (86k recording):


It's what I hear dialling into our Asterisk box. As soon as the call
receiver makes a sound (clicking fingers in that recording), the line
makes a brief buzzing noise, then goes crazy with raw static.

There is a longer recording and configuration info at:


The odd thing is, we have two phonelines, and the connection quality of
the second line coming into Asterisk is perfect.

Our Asterisk box is hooked up (in parallel with a NEC PBX) to our public
phone line via a TDM404P card.

Does this ring any bells for anyone?
