<DIV><FONT face=Arial size=2><SPAN class=764191516-30032007>We are having
intermittent problems where the person we call reports static when we place
an outgoing PSTN call. Only the person called hears static, to us the
conversation sounds fine. Never happens on inbound calls. It doesn't
matter what channel you call from (IAX, SIP, or Zap). We have a
Sangoma A108D with hardware echo cancellation with 2 PRIs to Level3 and 2 PRIs
to a Nortel Option 61c and then several IAX trunks running into this box as
well. Box is HP DL 385 G2. I've ruled out bad cables, bad port on
sangoma and bad port at Level3 rack. When under load and while the problem
is occurring zttest is never less than 99.987793 and is usually 100.
Nothing showing up in any logs anywhere. Not sure it is related, but I'm
noticing a very loud click when an incoming or outgoing call is initiated that I
don't remember in the past.</SPAN></FONT></DIV>

Anyone ever experience this? Suggestions for further trouble
