problematic hardware to a different location (along with a few phones) and test
it there? If you were able to take that equipment to your office or house and
test standard POTS lines there and don’t have a problem, you will know
right away that it is Telco or something ‘outside’ the router
causing the interference.<o:p></o:p></span></font></p>

font-family:Arial'>I’ve been battling this issue with what was suppose to
be a simple little CME install for 10 people for a little while now and
I’m at my wits end. My customer has a 2801 router with VIC2-4FXO a single
PVDM2-8 DSP and an 8 port powered Etherswitch module. I have turned vad on/off,
comfort noise on/off, I have played with input gain, output gain, and impedance
settings. I tested the pots lines with a regular analog phone I get no noise at
all. When making a call as soon as the call is connected the static starts.
Internal IP to IP phone calls are great and calls over the WAN are great. TAC
had me do a procedure where I captured the voice to a wav file before it went
through the DSP and after it went through the DSP and the static can not be
heard. I also got the TELCO in to test the lines for any nuances and I had the
customer ground the rack the 2801 was mounted into. Lastly TAC shipped me all
brand new equipment but the problem still persists after I swapped it out.<o:p></o:p></span></font></p>

fine and since I can plug a regular phone into the line and get no noise it is
