[Freeswitch-users] Second transfer

23 Feb 2011

      Hello,

I'm using att_xfer to make call transfer, like that:
A calls B
B calls C
B hangup and A is bridged do C

The thing is, the way I am trying to do it, C is able to transfer the call
again.
I don't want that C be able to transfer the call again.
The call should be transfered only once.
Is it possible?

This is my dialplan:

<include>

   <extension name="test_extension">
      <condition field="destination_number" expression="^numberB$">
         <action application="set" data="bind_meta_key=*"/>
         <action application="bind_meta_app" data="3 b s
execute_extension::transferencia XML public"/>
         <action application="bridge" data="sofia/gateway/test/loginB"/>
      </condition>
   </extension>

   <extension name="transferencia">
      <condition field="destination_number" expression="^transferencia$">
         <action application="read" data="3 3 base256/16000/sound.wav
attxfer_callthis 30000 #"/>
         <action application="execute_extension" data="transferencia2"/>
      </condition>
   </extension>

   <extension name="transferencia2">
      <condition field="${attxfer_callthis}" expression="^numberC$">
         <action application="att_xfer" data="sofia/gateway/test/loginC"/>
      </condition>
      <condition field="${attxfer_callthis}" expression="^numberD$">
         <action application="att_xfer" data="sofia/gateway/test/loginD"/>
      </condition>
   </extension>

</include>

Thank you,
