Introduction

This article is to give an overview to install FreeSWITCH with its default settings.

$ sudo yum update $ sudo yum groupinstall "Development tools" -y $ sudo yum install git autoconf automake libtool gcc-c++ libuuid-devel zlib-devel libjpeg-devel ncurses-devel openssl-devel sqlite-devel.x86_64 curl-devel pcre-devel speex-devel ldns ldns-devel libedit-devel gtk+-devel gtk2-devel ntpdate yasm-devel.x86_64 lua-devel opus-devel libshout-devel  libsndfile-devel

Following is the step by step guide for installing FreeSWITCH.

Step # 1

Download and extract FreeSWITCH source:

$ cd /usr/local/src/ $ sudo git clone https://freeswitch.org/stash/scm/fs/freeswitch.git

Step # 2

Compile & Install FreeSWITCH with libyuv:

$ cd /usr/local/src/freeswitch $ cd libs $ sudo git clone https://freeswitch.org/stash/scm/sd/libyuv.git $ cd libyuv $ sudo make -f linux.mk CXXFLAGS="-fPIC -O2 -fomit-frame-pointer -Iinclude/" $ sudo make install $ sudo　cp /usr/lib/pkgconfig/libyuv.pc /usr/lib64/pkgconfig/ $ cd ../../ $ sudo ./bootstrap.sh # If you want to change installation directory the use following command: $ sudo ./configure --prefix=<desired location path> # If you are facing issues of libyuv then you can use following command: $ sudo ./configure $ sudo make cd-sounds-install cd-moh-install $ sudo make $ sudo make install

If you encounter below error while compiling Freeswitch:

making all mod_opus make[4]: Entering directory '/usr/local/src/freeswitch/src/mod/codecs/mod_opus' Makefile:884: *** You must install libopus-dev to build mod_opus.  Stop. make[4]: Leaving directory '/usr/local/src/freeswitch/src/mod/codecs/mod_opus' Makefile:645: recipe for target 'mod_opus-all' failed make[3]: *** [mod_opus-all] Error 1 make[3]: Leaving directory '/usr/local/src/freeswitch/src/mod' Makefile:555: recipe for target 'all-recursive' failed make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory '/usr/local/src/freeswitch/src' Makefile:2948: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/usr/local/src/freeswitch' Makefile:1346: recipe for target 'all' failed make: *** [all] Error 2

You need to comment following lines in source and then recompile again:

vi freeswitch/src/mod/codecs/mod_opus/Makefile # Comment line 889 & 890 #install: error #all: error

-------------------------- FreeSWITCH configuration --------------------------   Locations:       prefix:          /usr/local/freeswitch       exec_prefix:     /usr/local/freeswitch       bindir:          ${exec_prefix}/bin       confdir:         /usr/local/freeswitch/conf       libdir:          ${exec_prefix}/lib       datadir:         /usr/local/freeswitch       localstatedir:   /usr/local/freeswitch       includedir:      /usr/local/freeswitch/include/freeswitch       certsdir:        /usr/local/freeswitch/certs       dbdir:           /usr/local/freeswitch/db       grammardir:      /usr/local/freeswitch/grammar       htdocsdir:       /usr/local/freeswitch/htdocs       fontsdir:        /usr/local/freeswitch/fonts       logfiledir:      /usr/local/freeswitch/log       modulesdir:      /usr/local/freeswitch/mod       pkgconfigdir:    ${exec_prefix}/lib/pkgconfig       recordingsdir:   /usr/local/freeswitch/recordings       imagesdir:       /usr/local/freeswitch/images       runtimedir:      /usr/local/freeswitch/run       scriptdir:       /usr/local/freeswitch/scripts       soundsdir:       /usr/local/freeswitch/sounds       storagedir:      /usr/local/freeswitch/storage       cachedir:        /usr/local/freeswitch/cache ------------------------------------------------------------------------------

Step # 3

Create freeswitch user for running freeswitch:

# create user 'freeswitch' # add it to group 'daemon' # change owner and group of the freeswitch installation $ cd /usr/local $ sudo useradd --system --home-dir /usr/local/freeswitch -G daemon freeswitch $ sudo passwd -l freeswitch    $ sudo chown -R freeswitch:daemon /usr/local/freeswitch/ $ sudo chmod -R 770 /usr/local/freeswitch/ $ sudo chmod -R 750 /usr/local/freeswitch/bin/*    $ sudo mkdir /var/run/freeswitch $ sudo chown -R freeswitch:daemon  /var/run/freeswitch    $ sudo ln -s /usr/local/freeswitch/bin/freeswitch /usr/bin/ # needed by /etc/init.d/freeswitch

Step # 4

Edit codecs priority and SIP Port for running Freeswitch as desired:

$ sudo vi /usr/local/freeswitch/conf/vars.xml .... #Adding VP8 Video Codec <X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,G722,PCMU,PCMA,GSM,VP8"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA,GSM,VP8"/>  ..... #Change SIP Port <X-PRE-PROCESS cmd="set" data="internal_sip_port=6000"/>

Step # 5

Create symbolic links for FreeSWITCH executables:

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

Step # 6

Create FreeSWITCH init script:

$ sudo touch /etc/init.d/freeswitch $ sudo chmod a+x /etc/init.d/freeswitch $ sudo vi /etc/init.d/freeswitch

Add following code in init script of FreeSWITCH:

#! /bin/sh # # freeswitch:       Starts the freeswitch Daemon # # chkconfig: 345 96 02 # processname: freeswitch # description: Freeswitch centos init script \ # config: # Author: gled # Source function library. . /etc/init.d/functions . /etc/sysconfig/network PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/freeswitch/bin DESC="FreeSwitch Voice Switching System" NAME=freeswitch DAEMON=/usr/local/freeswitch/bin/$NAME PIDFILE=/usr/local/freeswitch/log/$NAME.pid do_setlimits() {         ulimit -c unlimited         ulimit -d unlimited         ulimit -f unlimited         ulimit -i unlimited         ulimit -n 999999         ulimit -q unlimited         ulimit -u unlimited         ulimit -v unlimited         ulimit -x unlimited         ulimit -s 244         ulimit -l unlimited         return 0 } base=${0##*/} do_start() {         do_setlimits         $DAEMON -nc         RETVAL=$?         if [ $RETVAL = 0 ]; then                 success $"$base startup"         else                 failure $"$base startup"         fi         echo         return $RETVAL } do_stop() {         $DAEMON -stop         RETVAL=$?         [ $RETVAL = 0 ] && success $"$base shutdown" || failure $"$base shutdown"         rm -f $LOCKFILE         echo         return $RETVAL } # See how we were called. case "$1" in   start)         do_start         ;;   stop)         do_stop         ;;   restart)         do_stop         echo "Waiting for daemon to exit..."         sleep 5         do_start         ;;   *)         echo $"Usage: $0 {start|stop}"         exit 2         ;; esac exit $RETVAL

Step # 7

Starting FreeSWITCH:

$ sudo service freeswitch start 12759 Backgrounding.                                             [  OK  ]

Entering into the FreeSWITCH cli mode:

$ cd ~ $ fs_cli .=======================================================.                                                        |            _____ ____     ____ _     ___

Step # 7

Now you can test extension to extension calling by registering any of the default users 1000-19 with password 1234.
