By default, and when setting to "yes," echo cancellation is enabled and set to 16 ms (128 taps). Echo cancellation is explicitly disabled by setting: echocancel = no Digium does not recommend that users set echo cancellation to "no." Users of open source Asterisk-based echo cancelers also have the following options: echocancel = 128 (this sets 128 taps or 16ms) Digium, Inc. - Page 42 If audio quality is affected, reduce the taps length or combine your TE400 Series card with Digium's VPMOCT128. Users of Digium's VPMOCT128 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."...
