hello folks,

anyone knows how to pass a Release cause/ Disconnect Reason when firing respond from a dialplan ... e.g.:

Ive tried with sip_h_Reason=Q.850;cause=27 but it is not working :)

   <extension name="parseResult">
      <condition field="destination_number" expression="^parseResult$"/>
      <condition field="${componentStatus}" expression="^1$" break="on-true">
         <action application="log" data="INFO ######################## CALL FAILED REASON 1' ##########\n"/>

         <action application="set" data="sip_h_Reason=Q.850;cause=16"/>

         <action application="respond" data="480 Temporarily Unavailable"/>
      </condition>
   </extension>

any hint?
