Interesting, Is this just a more advanced software echo canceller or software with hardware hooks or software with hardware assisted processing?
How would it compare to a true hardware echo canceller like the one Sangoma uses. Besides the extra CPU cycles required. -----Original Message----- From: Nic Bellamy [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 13, 2007 12:41 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] The High Performance Echo Canceller (HPEC) Larry Shields wrote: > I recently read about the following new technologies from Digium.

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.
