Chapter 3: Configuration

Users of open source Asterisk-based echo cancelers also have the

following options:

echocancel = 128 (this sets 128 taps or 16ms)

echocancel = 256 (this sets 256 taps or 32ms)

Audio quality issues may result from choosing a taps length greater than

the server's ability to process the echo in real-time. If audio quality is

affected, reduce the taps length or combine your TE800 Series card with

Digium's VPMOCT256.

Users of Digium's VPMOCT256 hardware echo cancellation module will

have 128ms of echo cancellation performed at all times unless explicitly

disabled by setting the echocancel variable equal to "no."
