- Overlap sending (dialtone and additional digits)

- Tuneable latency: you can configure the size of B3 blocks at compile time
|

The default is 160 samples, for non-VoIP use you can tune it down to 130

Enable/Disable echocancel:
|
||||
Enable or disable echo-cancel provided by CAPI driver/hardware.
|
||||
You may need to disable echo-cancel when e.g. data/fax transmission handled
|

by non-CAPI application.
|
||||
Example:
|

exten => s,1,capicommand(echocancel|yes)

exten => s,1,capicommand(echocancel|no)
