asterisk users - Nov 2004 - SetVar ALERT_INFO

Hello,

I've got my dialplan configured to do a double ring when a customer 
service call comes in, and a normal ring when an extension  is dialed 
directly.  When a customer service call is transferred, I want to ring 
to revert back to normal.

In the local extension macro, I have the following


; make sure ring is set to default
exten => s,n,NoOp(${ALERT_INFO})
exten => s,n,NoOp(${_ALERT_INFO})
exten => s,n,SetVar(ALERT_INFO=)
exten => s,n,SetVar(_ALERT_INFO=)
exten => s,n,NoOp(${ALERT_INFO})
exten => s,n,NoOp(${_ALERT_INFO})

When a call is transferred, here's what I see on the console

   -- Executing NoOp("Zap/1-1", "Bellcore-r3") in new stack
   -- Executing NoOp("Zap/1-1", "") in new stack
   -- Executing SetVar("Zap/1-1", "ALERT_INFO=") in new
stack
   -- Executing SetVar("Zap/1-1", "_ALERT_INFO=") in new
stack
   -- Executing NoOp("Zap/1-1", "") in new stack
   -- Executing NoOp("Zap/1-1", "") in new stack

It appears as though both ALERT_INFO and _ALERT_INFO are not set.  This 
isn't the case, however, because the party receiving the transferred 
call still hears the double ring.

Now, I'm not sure if this is design or bug.  I think I saw mention of 
the _ doing something special but I'm not sure where and see no mention 
of it in the wiki under SetVar.

Pointers would be appreciated.

Thanks,
Trevor Peirce

; make sure ring is set to default
exten => s,n,NoOp(${ALERT_INFO})
exten => s,n,NoOp(${_ALERT_INFO})
exten => s,n,SetVar(ALERT_INFO=Bellcore-r3)
exten => s,n,SetVar(_ALERT_INFO=Bellcore-r3)
exten => s,n,NoOp(${ALERT_INFO})
exten => s,n,NoOp(${_ALERT_INFO})

Its very helpful if you actually set them to something.  The existence of
the variable isn't enough.
