Install Certified Asterisk 13 on CentOS7 / RedHat7

Asterisk is an open source PBX (private branch exchange) server that manage telephone calls. It include features such as customer service queues, music on hold, conference calling, and call recording, and many more.

Setup a machine with Cent-OS/Red-hat 7, and follow below steps.

1 - Disabled SE-Linux

vi /etc/selinux/config

And set SELINUX to disable

SELINUX=disabled

2 - Update installed Cent-OS/Red-hat 7 with latest packages.

yum update

3 - Stop Linux firewall, or add appropriate rules to allow asterisk related ports for clients and other services.

To stop Cent-OS/Red-hat 7 firewall

systemctl stop firewalld

If need to disable firewall permanently

systemctl disable firewalld

To stop Cent-OS/Red-hat 7 iptables permanently(if started)

systemctl stop iptables

If need to disable firewall permanently

systemctl disable iptables

4 - After updating Cent-OS/Red-hat 7 with latest packages restart the server to apply changes and setting properly.

reboot Or init 6

5 - After server gets reboot properly reconnect server and install required dependencies for Asterisk.

To install dependencies run below commands

yum install -y epel-release dmidecode gcc-c++ ncurses-devel libxml2-devel make wget openssl-devel newt-devel kernel-devel sqlite-devel libuuid-devel gtk2-devel jansson-devel binutils-devel bzip2 vim sox libtool* make gcc patch perl flex-devel gcc-c++ ncurses-devel flex libtermcap-devel autoconf* automake* libxml2-devel cmake wget vim sox httpd sqlite sqlite-devel bison make wget openssl-devel ncurses-devel  newt-devel libxml2-devel kernel-devel gcc gcc-c++ sqlite-devel libuuid-devel

yum install -y "kernel-devel-uname-r == $(uname -r)"

6 - To install asterisk JSON support is required (this typically means the libjansson development package is required).

To install libjansson development package follow below steps,

Go to /usr/src directory.

cd /usr/src/

Use wget to download the required source code for installation.

wget http://www.digip.org/jansson/releases/jansson-2.5.tar.gz

Extract it.

tar -zxf jansson-2.5.tar.gz

Go to the newly created directory.

cd jansson*

Compile the software.

./configure

Install package.

make clean
make
make install

7 - Installing PJPROJECT

PJPROJECT is Asterisk’s SIP channel driver. It is to provide improved call clarity and performance over older drivers.

Go to /usr/src directory.

cd /usr/src

Use wget to download the PJSIP source code for installation.

wget http://www.pjsip.org/release/2.3/pjproject-2.3.tar.bz2

Extract it.

tar -jxvf pjproject-2.3.tar.bz2

Go to the newly created pjproject directory.

cd pjproject-2.3

Compile the software.

./configure CFLAGS="-DNDEBUG -DPJ_HAS_IPV6=1" --prefix=/usr --libdir=/usr/lib64 --enable-shared --disable-video --disable-sound --disable-opencore-amr

To ensure all dependencies are properly in present.

make dep
make

Install package.

make install
ldconfig

To ensure the libraries have installed properly.

ldconfig -p | grep pj

If everything is properly  installed and configured you should get output something that looks like,

libpjsua2.so.2 (libc6,x86-64) => /lib64/libpjsua2.so.2

8 - Installing DAHDI (Optional)

DAHDI (Digium/Asterisk Hardware Device Interface), is the kernel module that controls telephone interface cards(PRI Card). These cards are usually used when adding Asterisk to an existing call center that uses older technology, such as PRI or Analog telephone channels.

To install DAHDI follow below process:

Go to /usr/src directory.

cd /usr/src

Download the latest version of DAHDI

wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz

Untar it.

tar -zxvf dahdi-linux-complete-current.tar.gz

Go to DAHDI directory.

cd dahdi-linux-complete-*

Build DAHDI for installation.

make

Install DAHDI

make install
make config

9 - Installation LibPRI (Optional)

Libpri is an open source library that helps to communicate over ISDN Primary Rate Interfaces (T1, E1, J1) protocols. libpri is a dependency for Asterisk and DAHDI if PRI, BRI and QSIG signaling is used. Required for PRI/BRI only.

To install LibPRI follow below process:

Go to /usr/src directory.

cd /usr/src

Download the latest version of LibPRI

wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-current.tar.gz

Untar LibPRI,

tar xvfz libpri-<version>

Go to LibPRI directory.

cd libpri*

Build LibPRI for installation, and install it.

make
make install

NOTE: If there are any error messages while trying to the above commands, you are missing some system dependencies listed in previous steps

Configuring and Building Asterisk source code

./configure --libdir=/usr/lib64

If every thing is proper you will Asterisk (*) ASCII image will be seen,
If you don't get below image it means there are any missing dependencies,
Install them, execute " make distclean " to remove cached Data and retry configure and build asterisk source codec.
