PBX Dialing Codes
– Four (4) one or two-digit PBX Trunk Access Codes can be defined in the
system database. When dialed as the first digit(s), these codes signal the system to apply the
appropriate COS. If not dialed, the call is treated as an internal PBX call and dialing is not
restricted.
Exception Tables
– Each Exception Table permits entry of 50 Allow codes and 50 Deny codes.
Each code can contain up to 20 digits including digits 0-9,
“#” as a wild card (any digit) and “*”
as the end of entry mark. Reference the previous charts for application of the Exception Tables.
Exception Table process
– As digits are dialed, they are compared to entries in the appropriate
Exception Table. Based on the Allow and Deny entries, the system applies the following rules
to allow or deny the call.
Rule 1 If a table has no entries, no restrictions are applied.
Rule 2 If there are only Deny entries, restrictions are provided as Deny only.
Rule 3 If there are only Allow entries, restrictions are provided as Allow only.
If there are both Allow and Deny entries, the Deny entries are searched. If the
Rule 4
dialed number matches a Deny entry, the call is restricted; if no match is found
the call is allowed.
