CentOS Asterisk installation

Required packages :

• Minimal install
• kernel-devel / kernel-smp-devel
• bison
• openssl-devel
• gcc

1. Install the required packages using yum
yum install kernel-devel bison openssl-devel gcc
2. Install zaptel
make
make install
make install-udev

If the kernel module compiled, try
modprobe ztdummy (only if using ztdummy)
modprobe zaptel
modprobe wcfxs
which should quietly load the zaptel kernel module and not output any error message

You will need the kernel modules to load when your Asterisk computer boots. You can try the commands:
cd /usr/src/zaptel
make config

3. Install Asterisk
$ make mpg123 ;configure for music on hold
$ make
$ make install
Create sample files to be created in /etc/asterisk
$ make samples

#If you want program docs/manual pages for asterisk
make progdocs

#If you want “service asterisk restart” command to work do this
make config

$ apt-get install linux-header-`uname -a’
If you want to use analog phone or call to PSTN, please buy an Digium Card.

4. Configure Card
$ sudo vi /etc/zaptel.conf
I uses TDM411 with FXS module on port 3, FXO module on port 4. So that, I add these line
fxoks=3
fxsks=4
I have no mistake here. FXS module use FXO signal, and FXO use FXS signal.
It’s time to check does it right. Please type this command in your console
$ ztcfg -vvv
If you receive message like this:
Channel 03: FXO Kewlstart (Default) (Slaves: 03)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)

2 channels configured.
Everything ok. Anything else, please check your module and /etc/zaptel.conf
