[Asterisk-Users] SetVar ALERT_INFO

[Brian West]

; 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.
