[Asterisk-Users] Asterisk and Sirrix PCI4S0 echo cancellation

[David Wilson]

Hi guys,

I'm running a Sirrix PCI4S0 quad BRI card in a box with Asterisk CVS-HEAD (20050614).
Something I've come across is that with 'echocancel = yes' in /etc/asterisk/sirrix.conf the echo is unbearably loud - so loud in fact that the echo distorts.

To remedy this I've set 'echocancel = no' and disabled the echo cancellation. With the echo cancellation disabled there is still an echo but it is much softer.

Any ideas on how I can turn on the echo cancellation again without having the very loud echo back ?
Is there some way I could perhaps drop the TX volume out of the Sirrix card ? Perhaps this would help ?

Thanks in advance.


Kindest regards
David Wilson
