<div>we have a remote site on an old PBX, analog phones (ick). They are moving to a new office with shiny new 7961's waiting for everyone (yeah) that doesn't happen until February and this started happening....</div>
<div> </div>
<div>Gateway is 2610 (12.3) running MGCP and has a EN Voice 2V module with 2 2-port FXS cards in it. When the remote site wants to dial someone by extension they dial 7+ and grab an FXS line and go...has worked great for 2 years. Now there is noise (severe static) on the second and fourth FXS line...(1/0/1 and 1/1/1 voie-ports respectively).
</div>
<div> </div>
<div>I changed out FXS cards, I changed out EN's in case it was a DSP issue. I even changed out 2610 chassis's and still the static. I replaced cabling to PBX and had vendor replace line card in PBX. If I reset the voice-ports (shut/no shut) they run clean about 4-8 hours and then the static comes back.
</div>

<div>I am running <em><strong>debug voice ccapi inout</strong></em> and everything seems to be smooth... is there a better debug command to capture this issue?</div>

<div>Has anyone experienced this before...</div>

<div>Short of opening a TAC case, I can't think of what teh next step should be...</div>

<div>Thanks in advance </div>
