[Freeswitch-dev] call forward howto

[Brian West]

You can also try this:

<extension name="Eeee">
   <condition field="destination_number" expression="^(23)$">
     <action application="set" data="continue_on_fail=true"/>
     <action application="bridge" data="sofia/default/$1%$${domain}"/>
     <action application="respond" data="181 Call is being forwarded"/>
     <action application="export" data="sip_h_Diversion=23@$$ 
{domain};reason=unavailable"/>
     <!-- Since we are a B2BUA this just sends the call back into the  
dialplan which would be the same as bridge sofia/default/22%$${domain}  
-->
     <action application="transfer" data="22"/>
   </condition>
</extension>
