best tools to tune the card named fxotune. To tune your card first shutdown the asterisk service and then

run:

# /usr/sbin/fxotune -i 0

I put 0 (zero) because to dial an outside line I set the asterisk configuration to use 0. You should change

it to whatever number you use. fxotune will create /etc/fxotune.conf file to put all the configuration it

creates to reduce the echo. Pleas read "man fxotune" for more explanation about the tools.

To enable Asterisk to use the card configuration every time we boot the server we need a slight

modification of init script. We should call the fxotune before we call Asterisk, you can either modify

the init script of Asterisk to call fxotune before it call the Asterisk or you can modify

/etc/init.d/after.local (yes, I use openSUSE). I prefer to use after.local. Create /etc/init.d/after.local and

fill the lines below:

# ! /bin/sh

/usr/sbin/fxotune -s

sleep 1

/etc/init.d/asterisk161 start

Also you need to remove asterisk service from init script

# insserv -r /etc/init.d/asterisk161

You can boot the server and hear the difference. If everything goes well you can hear no echo

Now let’s take a look back to our extension.conf that I already give in the part 3.
