[Asterisk-Users] Asterisk and Sirrix PCI4S0 echo cancellation

[David Wilson]

Hi Altus,

Thanks for your reply.

Yes I do get those errors. Any ideas what causes them ?

>email this guy,he wrote a patch to bring down the volume
Thanks I've been chatting with Steve already.

For some reason the patch does not seem to be working with my newer version 
of the Sirrix drivers....either that or I'm doing something wrong. :)
Did you have to modify the patch in any way or did you just apply it 'as is' 
?

I will keep in touch to let you know the outcome.

Many thanks.

Kindest regards
David Wilson
