Prerequisites

To follow along with this guide, you need one Ubuntu 20.04 LTS server which has prerequisite packages installed and configured. In order to install required packages issue the following command:

$ sudo apt install --yes git build-essential pkg-config uuid-dev zlib1g-dev libjpeg-dev libsqlite3-dev libcurl4-openssl-dev \
            libpcre3-dev libspeexdsp-dev libldns-dev libedit-dev libtiff5-dev yasm libopus-dev libsndfile1-dev unzip \
            libavformat-dev libswscale-dev libavresample-dev liblua5.2-dev liblua5.2-0 cmake libpq-dev \
            unixodbc-dev autoconf automake ntpdate libxml2-dev libpq-dev libpq5 sngrep

Starting from FreeSWITCH version 1.10.4 You have to Download, Compile and install sofia-sip and spandsp libraries separately

In order to install Sofia-Sip library, you need to download the latest code from FreeSWITCH’s official Packages repository

Installing Sofia-Sip library

Clone the official Sofia-Sip repository into /usr/local/src directory

$ sudo git clone https://github.com/freeswitch/sofia-sip /usr/local/src/sofia-sip

Now run following commands in sequence to install the library

$ cd /usr/local/src/sofia-sip
$ sudo ./bootstrap.sh 
$ sudo ./configure --prefix=/usr
$ sudo make && make install
$ sudo ldconfig

To verify if Sofia-Sip library is installed correctly in your system, run following command

$ ldconfig -p | grep sofia

If libsofia-sip is not installed, there will be no output. If it is installed, you will get a line for each version available.

Installing SpanDSP library

Clone the SpanDSP repository from FreeSWITCH packages repository into /usr/local/src directory

$ sudo git clone https://github.com/freeswitch/spandsp /usr/local/src/spandsp

Now run following commands in sequence to install the library

$ cd /usr/local/src/spandsp
$ sudo ./bootstrap.sh 
$ sudo ./configure --prefix=/usr
$ sudo make && make install
$ sudo ldconfig

To verify if SpanDSP library is installed correctly in your system, run following command

$ ldconfig -p | grep spandsp

If libspandsp is not installed, there will be no output. If it is installed, you will get a line for each version available.

You are now ready to install FreeSWITCH

Installing FreeSWITCH

Download the FreeSWITCH 1.10.6 release into /usr/local/src directory

$ sudo wget -c https://files.freeswitch.org/releases/freeswitch/freeswitch-1.10.6.-release.tar.gz -P /usr/local/src 

Extract the release file:

$ cd /usr/local/src
$ sudo tar -zxvf freeswitch-1.10.6.-release.tar.gz
$ cd freeswitch-1.10.6.-release

Run the configure script:

$ sudo CFLAGS="-Wno-unused-but-set-variable" disable_cc=yes \
       ./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc \
                   --with-gnu-ld --with-openssl --enable-zrtp

Disable signalwire module:

$ sudo sed -i 's/applications\/mod_signalwire/#applications\/mod_signalwire/' modules.conf

Now you are ready to compile and install FreeSWITCH, run the following:

$ sudo make 
$ sudo make install 

To install sound and music on hold run following:

$ sudo make cd-sounds-install
$ sudo make cd-moh-install 

FreeSWITCH is now installed and you can confirm it by running sudo freeswitch -nonat from your terminal

Post install setup

Create an unprivileged user
