Installing Asterisk PBX with an OpenVox ISDN card
This is a step-by-step guide to install Asterisk & FreePBX using an OpenVox ISDN cards
Install required packages
Add rpmforge repository
rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
Update the system
yum update
Install required packages
yum install bison bison-devel ncurses ncurses-devel zlib zlib-devel openssl openssl-devel gnutls-devel gcc gcc-c++ libxml2-devel libtiff-devel mysql-server php-gd php-mysql ncurses-devel audiofile-devel subversion libogg-devel mysql-devel e2fsprogs-devel keyutils-libs-devel krb5-devel libselinux-devel libsepol-devel libxml2-devel libtiff-devel gmp php-pear php-pear-DB php-pdo perl-DateManip sendmail-cf lame doxygen
Install kernel sources depending on your installation
yum install kernel-devel or yum install kernel-smp-devel
Finally disable selinux by editing /etc/selinux/config to :
| # This file controls the state of SELinux on the system. SELINUX=disabled # SELINUXTYPE= type of policy in use. Possible values are: SELINUXTYPE=targeted |
Download the sources:
cd /usr/src
wget http://downloads.digium.com/pub/asterisk/asterisk-1.4-current.tar.gz
wget http://downloads.digium.com/pub/asterisk/asterisk-addons-1.4-current.tar.gz
wget http://downloads.digium.com/pub/zaptel/zaptel-1.4-current.tar.gz
wget http://downloads.digium.com/pub/libpri/libpri-1.4-current.tar.gz
wget http://downloads.digium.com/pub/telephony/sounds/asterisk-core-sounds-en...
wget http://mirror.freepbx.org/freepbx-2.4.1.tar.gz
create a symbolic link for the kernel sources
ln -s kernels/2.6.18-92.1.10.el5.centos.plus-i686/ linux
Unpack the source files :
tar zxvf asterisk-1.4-current.tar.gz
tar zxvf asterisk-addons-1.4-current.tar.gz
tar zxvf zaptel-1.4-current.tar.gz
tar zxvf libpri-1.4-current.tar.gz
tar zxvf freepbx-2.3.1.tar.gz
Configure and compile each package seperately
cd /usr/src/zaptel-1.4-21.1
./configure
make
make install
make config
Edit /etc/sysconfig/zaptel and comment out every line except
| MODULES="$MODULES ztdummy" # UHCI USB Zaptel Timing Only Interface |
Start zaptel service
/etc/init.d/zaptel start
/sbin/ztcfg
cd /usr/src/libpri-1.4.7/
make
make install
Since we are not using native Zaptel hardware we will use the mISDN module for
the OpenVox ISDN card
cd /usr/src/
wget http://www.misdn.org/downloads/mISDN.tar.gz
wget http://www.misdn.org/downloads/mISDNuser.tar.gz
tar xzf mISDN.tar.gz
tar xzf mISDNuser.tar.gz
cd mISDN-1_1_7_2/
make install
cd ../mISDNuser-1_1_7_2/
make install
We need to configure mISDN so type :
mISDN scan
mISDN config
Edit /etc/mISDN.conf and adjust your port modes either to ptp or ptmp
and start the mISDN service
mISDN start
Before we install asterisk we will need to create the corresponding users as well as
a number of directories
useradd -c "Asterisk PBX" -d /var/lib/asterisk asterisk
mkdir /var/run/asterisk
mkdir /var/log/asterisk
chown -R asterisk:asterisk /var/run/asterisk
chown -R asterisk:asterisk /var/log/asterisk
cd /usr/src/asterisk-1.4.21.2/
./configure
make menuselect and make sure chan_misdn is selected as well as anything else
you feel you might need
make install
make samples
make progdoc
We will need to edit some configuration files
vi /etc/asterisk/misdn.conf
| [general] misdn_init=/etc/mISDN.conf debug=4 ntdebugflag=0 ntdebugfile=/var/log/misdn-nt.log ntkeepcalls=no tracefile=/var/log/asterisk/misdn.log bridging=no stop_tone_after_first_digit=yes append_digits2exten=yes dynamic_crypt=no crypt_prefix=** crypt_keys=test,muh [default] context=misdn language=en musicclass=default senddtmf=yes far_alerting=yes allowed_bearers=all nationalprefix= internationalprefix= rxgain=0 txgain=0 te_choose_channel=no pmp_l1_check=no reject_cause=16 need_more_infos=no nttimeout=no method=standard overlapdial=yes dialplan=0 localdialplan=0 cpndialplan=0 early_bconnect=yes incoming_early_audio=no nodialtone=no immediate=yes hold_allowed=yes callgroup=1 pickupgroup=1 presentation=-1 screen=-1 echocancel=32 max_incoming=2 max_outgoing=2 [isdn] |

Now it is let's add some extras
cd /usr/src/asterisk-addons-1.4.7/
./configure
make
make install
To install FreePBX we will need to confiugre MySQL and Apache
/etc/init.d/mysqld start
mysqladmin create asterisk
mysqladmin create asteriskcdrdb
mysql asterisk < /usr/src/freepbx-2.4.1/SQL/newinstall.sql
mysql asteriskcdrdb < /usr/src/freepbx-2.4.1/SQL/cdr_mysql_table.sql
Connect to MySQL using :
mysql
and execure
GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO asteriskuser@localhost IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON asterisk.* TO asteriskuser@localhost IDENTIFIED BY 'password';
flush privileges;
quit
For FreePBX to function correctly it will need to run as the asterisk user
vi /etc/httpd/conf/httpd.conf
and edit the following lines :
| User asterisk Group asterisk . . . AllowOverride All |
chown -R asterisk:asterisk /var/lib/php/session/
Now let's install FreePBX
cd /usr/src/freepbx-2.4.1
./start_asterisk start
./install_amp
You will be prompted with several questions during installation:
* Enter your USERNAME to connect to the ?asterisk? database
- asteriskuser
* Enter your PASSWORD to connect to the ?asterisk? database
- password
* Enter the hostname of the ?asterisk? database
- locahost
* Enter a USERNAME to connect to the Asterisk Manager interface
- admin
* Enter a PASSWORD to connect to the Asterisk Manager interface
- amp111
* Enter the path to use for your AMP web root
- /var/www.
* Enter the IP ADDRESS or hostname used to access the AMP web-admin
- <ip-address>
* Enter a PASSWORD to perform call transfers with the Flash Operator Panel
- passw0rd
* Use simple Extensions [extensions] admin or separate Devices and Users [deviceanduser]
- extensions
* Enter directory in which to store AMP executable scripts
- /var/lib/asterisk/bin
* Enter directory in which to store super-user scripts
- /usr/sbin
chown asterisk:asterisk amportal.conf
and rerun ./install_amp
vi /var/www/html/recordings/includes/main.conf.php
| $ari_admin_password = "password"; |
Now let's make sure everything starts when it should :
chkconfig --level 235 httpd on
chkconfig --level 235 httpd on
chkconfig --level 235 httpd on
Edit /etc/rc.local and add at the end
| /usr/sbin/mISDN start /usr/local/sbin/amportal start |
Reboot the machine and upon restart
connect to asterisk
asterisk -r
Check that your isdn card is properly configured
misdn show stacks
that should return :
BEGIN STACK_LIST:
* Port 1 Type TE Prot. PMP L2Link DOWN L1Link:UP Blocked:0 Debug:4
* Port 2 Type TE Prot. PMP L2Link DOWN L1Link:DOWN Blocked:0 Debug:4
Now connect to FreePBX
http://<ip-adress>/admin and configure your SIP Extensions.
To make out bound calls you need to create a Custom Trunk and add to the dial string mISDN/1/$OUTNUM$
