[*] Echo - possible solution

[John Lange]

You probably can't solve the echo problems but make sure you have the
following:

First, use asterisk-1.4beta which has the most up to date echo
cancelers.

If you are not using 1.4, then in the file: zaptel-1.2.X/zconfig.h

Comment out the other echo cancelers and uncomment:

#define ECHO_CAN_MG2

And in /etc/asterisk/zapata.conf, make sure you have:

echocancel=yes ;or try echocancel=256
echotraining=yes

In theory there is no reason why the x100p can't have just as good of
echo cancellation as any other analog card (since they all use software
echo). The only thing I can think of is that since the x100p is
basically a software modem it has high CPU overhead which prevents the
software echo cancellation from working as well as it could.

Alternatively you could just buy a SIP channel from a provider ;) Then
you don't need a server or a phone line.
