[asterisk-users] Echo problem in the analoge lines

[bilal ghayyad]

Hi All;

To overcome the echo problem, what mainly I have to do in the configuration other than the following line in the system.conf under dahdi directory?

echocanceller=mg2,1-16

1) How can I know if the digium card supporting echo cancellator?
2) If I am getting a message in the consol that unable to enable the echo cancelator, then what does it means? The hardware is not supporting echo cancellation or there is a software problem?

Regards
Bilal
