[Freeswitch-users] Caller id when doing transfers

To answer my own question it appears that the information is available
in the sip_h_Referred-By variable.  E.g.:

  <extension name="system25_park">
     <condition field="destination_number" expression="^\*5$" />
     <condition field="${sip_h_Referred-By}" expression="^<sip:([0-9]{4})@.*$">

allows the station id making the transfer to be known when a call is
transfered to *5.  The station id can then be used to park the call in
the proper fifo.
