RealTime — Looks up information from the RealTime configuration handler



Uses the RealTime configuration handler system to read data into 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 => 123,2,SayNumber(${John_port})
