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.

Subject: [asterisk-users] When to use Echo Cancellation cards?
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?
