[Asterisk-Users] more cpu intensive echo cancellers ?

[Michael Collins]

Gerard,

I'll bet your side is working great for echo cancellation.  It sounds
like the equipment at the other end of the call might need some help.
You know the old rule if you and I are talking on the phone: If I hear
echo, you've got a problem; if you hear echo, I've got a problem.  If
only all echo problems were so easy to diagnose!  In any case, is it
possible that some of the echo you're hearing is being caused by poor
echo handling on the other end of the line?

Just a thought.

Hi,
I've had some decent luck with the mark3 echo canceller from the zaptel
driver, echos on about 20% of the calls, people I've called say I sound
great now, but our side hears echos.
I was wondering if there was any way to tweak the current software
cancelers into using more CPU (and hopefully doing a better job, close
to a hardware canceler), I only have 10 lines, and a single call takes
0.5% cpu, I would have no problem if it went up to 5-10% if they would
work better.
Or should I just give up now and buy the channel bank, tellabs hardware
echo canceler and a T1 pci card? (hope TDM400P cards have decent resale
value ;)
