[Asterisk-Users] Asterisk and Sirrix PCI4S0 echo cancellation

[David Wilson]

I'm using the ones from 10/06. I haven't put in the 16/06 ones yet. Have you 
tried them ?

>I turned echo off
Is your echo cancellation switched off  (echocancel = no) ?

Yea, I also get a 'watery' sound now and again.

With my echocancel set to 'no' everything works fairly well except that 
there's a slight echo, much softer than the echo I get when I have 
'echocancel = yes' with or without the patch applied.

Hows JHB today ? :)

Kindest regards
David Wilson
