General

Write a handler for tel links in your dialplan.

 <include>
   <extension name="handle_tel">
     <condition field="destination_number" expression="^tel:(.*)$">
       <action application="transfer" data="$1 XML default"/>
     </condition>
   </extension>
 </include>

Go to the about:config page and add the following new boolean properties.

network.protocol-handler.external.tel         true
network.protocol-handler.expose.tel           false
network.protocol-handler.warn-external.tel    false

Open up your favorite text editor and save the following script for your platform.

Windows - with a .bat extension.

c:\progra~1\freeswitch\fs_cli.exe -x "pa call %1"

Linux - executable by your user.

/usr/local/freeswitch/bin/fs_cli -x "pa call $1"

Click on any tel link on any page and Firefox should prompt you to open it up with an application... enter the path to your script, and all should be well with the world.
