I am working on a context that will check whether the call is transferred; if so, send it back, as I only want to accept original calls, not transferred ones. i.e., for paging so that calls don’t accidentally get transferred to the paging system. This is a FreePBX system, but more of an Asterisk question. This is what I have -
[page-timeout]
exten => _.,1,Noop(Page Timeout)
same => n,NoOp(Checking if call to paging is a transfer)
same => n,GotoIf($[${VARIABLE_EXISTS(BLINDTRANSFER)}]?transfer_blocked)
same => n,Set(TIMEOUT(absolute)=10)
same => n,Goto(app-pagegroups,${EXTEN},1)
same => n(transfer_blocked),NOOP(Recall Blind Call)
same => n,Set(ORIGINATOR=${CUT(BLINDTRANSFER,-,1)})
same => n,Wait(4)
same => n,Transfer(${ORIGINATOR})
same => n,Hangup()
exten=> h,1,Return
It works, sort of. The transfer is detected and blocked, but instead of the call ringing back, the call drops.

I have tried using Dial() instead of Transfer(), and I get basically the same result. The phone rings back, but the call drops, and when you pick up, the call is not there. I am not sure why, I have the h extension set to Return because if I remove it, the dialplan runs twice because it is called with a h on Hangup(), but I get the same result either way. I assume I’m misunderstanding something, but I can’t figure out why I can’t get the call to recall.
