LookupCIDName() Performs a lookup of a Caller ID name from the AstDB
LookupCIDName()

This application has been deprecated in favor of Set(CALLERID(name)=
${DB(cidname/${CALLERID(num)})})

Uses the Caller ID number on the active channel to retrieve the Caller ID name from
the AstDB (family cidname). This application does nothing if no Caller ID was received
on the channel. This is useful if you do not subscribe to Caller ID name delivery, or if
you want to change the Caller ID names on some incoming calls.
; look up the Caller ID information from the AstDB, and pass it along
; to Jane's phone
exten => 123,1,Answer()
exten => 123,2,LookupCIDName()
exten => 123,3,Dial(SIP/Jane)
