You could use a pattern match and then do a lookup in the database to see if
the
prefix exists:
[custom-inbound]
exten => _XXX,1,Verbose(2,Lookup prefix ${EXTEN})
exten => _XXX,n,Set(PREFIX=${EXTEN})
exten => _XXX,n,Set(PREFIX_EXISTS=${ODBC_GET_PREFIX(${PREFIX})})
exten => _XXX,n,GotoIf($["${PREFIX_EXISTS}" =
"1"]?prefixAllowed,1:prefixDisallowed)
exten => prefixAllowed,1,Verbose(2,Prefix ${PREFIX} Allowed)
exten => prefixAllowed,n,Playback(beep)
exten => prefixDisallowed,1,Verbose(2,Prefix ${PREFIX} Disallowed)
exten => prefixDisallowed,n,Congestion()
func_odbc.conf
[GET_PREFIX]
dsn=<something setup in res_odbc.conf)
readsql=SELECT 1 FROM prefix_table WHERE prefix = '${ARG1}'
Or something like that (untested).
