Freeswitch on Ubuntu Feisty

While listening to Ray LaMontagne, I’ve been playing with freeswitch on Ubuntu Feisty.

Starting from a bare bones feisty, well, actually a bare bones dapper (openvz template I downloaded) upgraded to feisty in one fell swoop.

Getting freeswitch:


apt-get install subversion subversion-tools
svn checkout http://svn.freeswitch.org/svn/freeswitch/trunk freeswitch

apt-get install autoconf automake libtool libmudflap0-dev libltdl3-dev\\
 flex bison gdb build-essential wget unixodbc-dev libnspr4
cd freeswitch
./bootstrap.sh
./configure --enable-core-odbc-support
cp build/modules.conf.in modules.conf

I edited modules.conf and uncommented spidermonkey. Spidermonkey is a javascript engine used by freeswitch to add functionality. So far for me, that’s just an answering machine.


make all
sudo make install

It installs in /usr/local/freeswitch

edit /usr/local/freeswitch/conf/freeswitch.xml


<!--#set "sip_profile=mydomain.com"-->

Assuming you don’t have srv records and know how to configure them, change mydomain.com to whatever fqdn resolves to the ip address freeswitch is installed on. I think (but I’m not sure ;) that you can choose any name you like, but it’s safer to use the fqdn for now.

You can leave the rest of the file alone.

edit /usr/local/freeswitch/conf/directory.xml

This is where you add extensions. You can modify that file, and add extensions, I moved it out of the way and created a new one like this.


<domain name="$${sip_profile}">
  <user id="100">
    <params>
      <param name="password" value="100"/>
    </params>
    <variables>
      <variable name="ruleset" value="internal" />
    </variables>
  </user>
  <user id="101">
    <params>
      <param name="password" value="101"/>
    </params>
    <variables>
      <variable name="ruleset" value="internal" />
    </variables>
  </user>
 <user id="102">
    <params>
      <param name="password" value="102"/>
    </params>
    <variables>
      <variable name="ruleset" value="internal" />
    </variables>
  </user>
</domain>

edit /usr/local/freeswitch/conf/spidermonkey.conf.xml

and add


<load module="mod_spidermonkey_etpan"/>

One more file to edit.

edit default_context.xml

add


  <extension name="internal">
    <condition field="destination_number" expression="^(10\\d)$">
      <action application="set" data="call_timeout=50" />
      <action application="set" data="hangup_after_bridge=true" />
      <action application="set" data="continue_on_fail=true" />
      <action application="bridge" data="sofia/${sip_profile}/$1%${sip_profile}" />
      <action application="javascript" data="answermachine.js" />
    </condition>
  </extension>

If you want to play with the answering machine, you’ll also need to download answermachine and edit it with your email address, etc, and save it as /usr/local/freeswitch/scripts/answermachine.js .

you can then cd to the bin directory and ./freeswitch

You should be able to register a couple of phones as 101, 102 and 103.

After you’ve made a few test calls, and everything appears to be working.

edit /usr/local/freeswitch/conf/sofia.conf.xml

change <param name=”accept-blind-reg” value=”true”/> to false
and uncomment <!–<param name=”auth-calls” value=”true”/>–>

Done, I’ve also setup a gateway which I’ll post about later
