[Asterisk-Users] Echo cancellation

[Peter Zeltins]

What is the status on echo cancellation in Asterisk/CAPI? I know Zaptel drivers will do echocancel, and chan_capi does have support for Eicon's echo cancellation, but what about the rest? I found in mailing list archives a patch description that will mute RX channel whenever signal level is 4 times lower than TX channel - has this patch made into chan_capi or Asterisk CVS yet?   Peter
