10.0pt;font-family:Arial;color:navy'>The phones are directly connected to the
powered ESM on the router. I have ruled out internal cabling issues by directly
connecting phones to the ESM. Also IP to IP calls work fine it is only PSTN
calls through the FXO ports. Another interesting thing that I have noticed is
that the static seems to only happen as I am talking into the IP phone. If the
PSTN person is talking and I am listening I hear no static. The moment I speak
into the IP phone I hear the background static in my ear. The PSTN person does
not hear the static. If I have a call connected and do not speak into the set
it sound clean. If I breath into the set I hear static, it is continuous as I
speak or add noise to the mouth-piece.<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>
