Thanks for helping.


[pre-dial-handler]
exten => s,1,Verbose(0,Entering context ${CONTEXT} in channel ${CHANNEL}
with EXTEN and CID set to ${EXTEN} and ${CALLERID(num)})
  same => n, Set(CHANNEL(hangup_handler_push)=hangup-handler,s,1)

[hangup-handler]
exten => s,1,Verbose(0,Entering context ${CONTEXT} in channel ${CHANNEL}
with EXTEN and CID set to ${EXTEN} and ${CALLERID(num)})

[to-foobar]
exten => _X.,1,Verbose(0,Entering context ${CONTEXT} with EXTEN and CID set
to ${EXTEN} and ${CALLERID(num)})
;  same => n, Set(CHANNEL(hangup_handler_push)=hangup-handler,s,1)
  same => n, Dial(SIP/foobar/${EXTEN},,b(pre-dial-handler^s^1))
  same => n, Hangup()

[from-foobar]
exten => _X.,1,Verbose(0,Entering context ${CONTEXT} with EXTEN and CID set
to ${EXTEN} and ${CALLERID(num)})
