[Freeswitch-users] how to get the gateway name which the call is using

[gggyniidt]

Hello

My dialplan like this:
  <extension name="test">
     <condition field="destination_number" expresion="^(100)$">
       <action application="bridge"
data="sofia/gateway/gw/100|sofia/gateway/gw1/100"/>
     </condition>
   </extension>

I want to know which gateway was using by the call, gw or gw1? is there any
variables to use?

Thanks!
