I recently read about the following new technologies from Digium. Has
anyone tried the new HPEC or knows when it will be available?
It's out now, and I've tried it - the difference between HPEC and MG2
from trunk is stunning - in situations with bad echo where MG2 can take
ten or more seconds to converge to a reasonable degree, HPEC does it in
perhaps 300ms - converging on my intake of breath before I say "hello",
and absolutely no echo after that unless I purposefully go out of my way
to screw it up (whistling/blowing into the handpiece for instance - even
then, the malfunction is minimal).
You can now buy it from the Digium website (US$10 per channel), or if
you have an in-warranty Digium card, email through the serial numbers to
Digium support and they'll give you a key (this is what I did).
You'll need Zaptel 1.2.13 to make it go.
It does take quite a bit of CPU though - perhaps 70% more compared to
MG2-trunk for the same number of taps from my rough measurements.
Cheers,
Nic.
