Setting Up Freeswitch On Debian 5 (Lenny)

Introduction

FreeSWITCH is an open-source telephony platform designed to facilitate the creation of voice and chat driven products scaling from a soft-phone up to a soft-switch. It can be used as a simple switching engine, a PBX, a media gateway or a media server to host IVR applications using simple scripts or XML to control the callflow.

 

Setup environment

OS: Linux
Distribution: Debian 5 (Lenny)
Date: 12/11/2009
Prerequisite: minimal install
Freeswitch version: 1.0.4

 

When/Where to use Freeswitch

Scenarios where freeswitch fits in:

Rating & Routing Server
Transcoding B2BUA 
IVR & Announcement Server
Conference Server
Voicemail Server 
SBC (Session Border Controller) 
Basic Topology Hiding Session Border Controller 
Zaptel, Sangoma, Rhino, PIKA Hardware Support (Analog and PRI)
And, of course, a PBX

 

Downloading Source

Debian lenny does not come with binaries of Freeswitch. Therefore we would be using “svn” repositories to build the binaries.

cd /usr/src
sudo apt-get install subversion build-essential autoconf automake libtool libncurses5 libncurses5-dev

svn checkout http://svn.freeswitch.org/svn/freeswitch/trunk freeswitch

This will download the source code from the web( ~311 Mb in size). Make sure you have Internet access.If you are behind proxy. Set the proxy in /root/.subversion/servers.

 

Building Binaries

cd freeswitch

Run the following command to check for any dependencies that may exist.

dpkg-checkbuilddeps

I needed these. Your requirements may vary. Fulfill them.

aptitude install automake1.9 unixodbc-dev libasound2-dev libcurl3-openssl-dev \
libcurl4-openssl-dev libssl-dev libogg-dev libvorbis-dev libperl-dev libgdbm-dev \
libdb-dev libgnutls-dev libtiff4-dev libmemcache-dev memcached libx11-dev

Start building the packages.

dpkg-buildpackage -rfakeroot

Note: During the building process still need Internet access. (The scripts fetch stuff fromt the web.)

Building process should take around 12 hours on a Pentium 4 with 1Gb ram & this should produce following debian packages (definitions listed only).

thanx. Im glad it is of use to someone. XML based config files are not for the faint-hearted although I must admit that I hate xml.

Cheers

Howdy, Your instructions worked pretty well, as far as they go. There were several missing .deb files and it built much quicker than you suggested. I am sure those two facts are related. I gather from from what I read elsewhere that the reason is that freeswitch separated the sound files out of the main package. I have not found them yet, but your instructions need to change, if you expect the sound file packages to be built. Finally, I would suggest you update the first page to reflect that these instructions don't actually produce a working system. The todo at the end saying that Trunking/Gateway was still needed is a big one. It is a good start, though. Good day
