[asterisk-users] Using * in extension name

[Daniel Hazelbaker]

Just to finish off this thread for anybody else who wants the same  
functionality:

As Philipp coded out, what I was originally doing was something akin  
to the following:

_*7. => {
	Pickup(${EXTEN:2}@to-users);
	Dial(Local/${EXTEN:2});
}

Somebody else wondered why I would do this as I wouldn't want to talk  
to the original callee.  Pickup() will never return if it successfully  
picks up the call.  So if it does return then we can assume (for now)  
that the phone is not ringing and then proceed to dial the number.

As I said, this did work perfectly.  However, I discovered that the  
Grandstream phones we use automatically prepend ** to the monitored  
extension.  So if the phone is not ringing it will dial 268, if the  
phone is ringing it will dial **268.  So in the end I ended up with:

_**. => { Pickup(${EXTEN:2}@to-users); }

And all works perfectly.  Obviously for other phones I would have to  
come up with something else like the above, but with the grandstreams  
it seems to work great.
