RealTime — Looks up information from the RealTime configuration handler
Uses the RealTime configuration handler system to read
data in to channel variables. All unique column names (from the
specified family
) will be set as channel
variables, with an optional prefix
to the
name (e.g., a prefix of var_
would
make the column name
become the
variable ${var_name}
).
; retrieve all columns from the sipfriends table where the name column
; matches "John", and prefix all the variables with "John_"
exten => 123,1,RealTime(sipfriends,name,John,John_)
; now, let's read the value of the column named "port"
exten => 123,n,SayNumber(${John_port})
