RealTime | Looks up information from the RealTime configuration handler |
RealTime( family , colmatch , value [, prefix ])
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})
