Dialplan /usr/local/freeswitch/conf/dialplan/default.xml Do a find for "Local_Extension" inside the file modify the bottom of that section. Comment out the following:

    <action application="bridge" data="user/${dialed_extension}@${domain_name}"/>

Then add:

    <action application="javascript" data="followme.js" />

Now it should look like this.

     <action application="javascript" data="followme.js" />
     <!--<action application="bridge" data="user/${dialed_extension}@${domain_name}"/>-->
     <action application="answer"/>
     <action application="sleep" data="1000"/>
     <action application="voicemail" data="default ${domain_name} ${dialed_extension}"/>

Add the follome javascript file to /usr/local/freeswitch/scripts/followme.js
