Installation from Source

1. Fetch updated list of packages

apt update -y

2. Install dependencies

apt install -y git subversion build-essential autoconf automake libtool libncurses5 libncurses5-dev make libjpeg-dev libtool libtool-bin libsqlite3-dev libpcre3-dev libspeexdsp-dev libldns-dev libedit-dev yasm liblua5.2-dev libopus-dev cmake

3. Lets install some optional packages too

apt install -y libcurl4-openssl-dev libexpat1-dev libgnutls28-dev libtiff5-dev libx11-dev unixodbc-dev libssl-dev python-dev zlib1g-dev libasound2-dev libogg-dev libvorbis-dev libperl-dev libgdbm-dev libdb-dev uuid-dev libsndfile1-dev

4. Now install signalwire related packages. First install libks.

apt install cmake
cd /usr/src
git clone https://github.com/signalwire/libks.git
cd libks
cmake .
make
make install

5. Then install signalwire-c

cd /usr/src
git clone https://github.com/signalwire/signalwire-c.git
cd signalwire-c
cmake .
make
make install

6. Now grab FreeSWITCH source. Use the -b flag to get a specific branch

cd /usr/src
git clone https://freeswitch.org/stash/scm/fs/freeswitch.git -bv1.8 freeswitch
cd freeswitch

7. As we are in a branch that will go through many rebases, to avoid conflicts better config rebase settings

git config pull.rebase true

8. Start bootstrapping

./bootstrap.sh -j

9. By default, only few modules are enabled. You can enable/disable these modules at this stage. Edit ‘modules.conf’ and change as per requirements. Remember enabling new modules may require additional dependencies.

10. Now run standard installation process

./configure -C
make
make install

11. Compile sounds

make all cd-sounds-install cd-moh-install

12. Create simlinks to use services easily.

ln -s /usr/local/freeswitch/bin/freeswitch /usr/bin/
ln -s /usr/local/freeswitch/bin/fs_cli /usr/bin

13. Add new group and user with less privileges to run FreeSWITCH service.

cd /usr/local
groupadd freeswitch
adduser --disabled-password  --quiet --system --home /usr/local/freeswitch --gecos "FreeSWITCH Voice Platform" --ingroup freeswitch freeswitch
chown -R freeswitch:freeswitch /usr/local/freeswitch/
chmod -R ug=rwX,o= /usr/local/freeswitch/
chmod -R u=rwx,g=rx /usr/local/freeswitch/bin/

14. Now lets add systemd unit file. Systemd is default init system for Ubuntu 18.04. Open new file ‘/etc/systemd/system/freeswitch.service’ using your favorite editor and copy below content in it.

[Unit]
Description=freeswitch
Wants=network-online.target
Requires=syslog.socket network.target local-fs.target
After=syslog.socket network.target network-online.target local-fs.target

[Service]
Type=forking
Environment="DAEMON_OPTS=-nonat"
EnvironmentFile=-/etc/default/freeswitch
ExecStartPre=/bin/chown -R freeswitch:freeswitch /usr/local/freeswitch
ExecStart=/usr/bin/freeswitch -u freeswitch -g freeswitch -ncwait $DAEMON_OPTS
TimeoutSec=45s
Restart=always

User=root
Group=daemon
LimitCORE=infinity
LimitNOFILE=100000
LimitNPROC=60000
LimitSTACK=250000
LimitRTPRIO=infinity
LimitRTTIME=infinity
IOSchedulingClass=realtime
IOSchedulingPriority=2
CPUSchedulingPolicy=rr
CPUSchedulingPriority=89
UMask=0007
NoNewPrivileges=false

[Install]
WantedBy=multi-user.target

15. Now start service and enable it to start on boot.

chmod ugo+x freeswitch.service
systemctl start freeswitch.service
systemctl enable freeswitch.service

16. Now check status of FreeSWITCH service
systemctl status freeswitch.service
Status should be ‘active’ something like below

● freeswitch.service – freeswitch
Loaded: loaded (/lib/systemd/system/freeswitch.service; enabled; vendor preset: enabled)
Active: active (running) since Mon 2019-05-27 10:55:15 UTC; 7min ago

17. Now you can connect to FreeSWITCH using client as below
fs_cli -r

Notes

During compilation if you stuck with errors like unknown dependencies (particularly spansdsp), run below command before starting compilation again.

git clean -fdx
