<DIV><FONT face=Arial size=2>I've been running Digium TDM400P with 2 FXO and now
I run a Sangoma A200 with 2 FXO and no hwec, both cards have suffered echo, one
of my lines is much worse than the other. I messed about for a year using
the software EC in Zaptel and whilst I could remove the echo on one line the
other would always take 10-20secs to sort its self out and somtimes would never
kill the echo. This situation never ever passed the wife test (that is
seriouse business). I was about to bite the bullet and get a Sagoma A200D
with HWEC when I discoved the new Digium software EC software called HPEC, it
works a treat and at $10 per channel it is much better then spending loads of
$$$ on a HWEC. I run it on a P3 650Mhz that seems to have no problem at
all keeping up.</FONT></DIV>

Echo Cancellation cards?</DIV>
<DIV><BR></DIV>In what scenarios non-Echo Cancellation cards (T1/E1/FXO)
should be used ? Don't all good and professional installations need echo
cancellation cards? Are there people out there with non-Echo Cancellation
cards for T1 or 8 FXO ports and who really don't have any echo issues and they
are running serious businesses? <BR clear=all><BR>-- <BR>Zeeshan A Zakaria
