<br><font size=2 face="sans-serif">Hi, I have had this issues for ages
but have ignored it, but my handsets get faint background crackle
on the FXS port. When I connect the handset directly into my PSTN, it goes
away complete, so I am generating this from somewhere in my asterisk box.
I get it immediately when the phone goes off-hook and it stays through
the dialing and call progress.</font>
<br>
<br><font size=2 face="sans-serif">I can't think of any other devices generating
any interference along the line anywhere between the FXS port and my phone
handset.</font>
<br>
<br><font size=2 face="sans-serif">Any ideas ?</font>
<br>
