If TOLL CALLS = Y (yes) in Function 321 (page F.23), the system checks the number dialed against the
Deny Exception table. If the number matches an entry in this table, the call is restricted. Otherwise, it’s allowed.
If TOLL CALLS = N (no) in Function 321 (page F.23):
1. First, the system checks the number dialed against the Allow Exception table.
If the number matches an entry in this table, the call is allowed.
Otherwise . . .
2. The number is checked against the Deny Exception table.
If the number matches an entry in this table, the call is restricted.
Otherwise . . .
3. The number is checked against the Fixed Allow table.
If the number matches an entry in this table, the call is allowed.
Otherwise . . .
4. The number is checked against the Fixed Deny table.
If the number matches an entry in this table, the call is denied.
Otherwise . . .
5. The call is allowed.
How toll restriction works
As a number is dialed (or a station speed-dial key is pressed), the system compares the number dialed,
starting with the first digit, until a match is found in one of the toll-restriction tables, in the order described
above under “If TOLL CALLS = N (no).” If no match is found, the default is to allow the call.
Example: Extension 101 is set with TOLL CALLS = N in Function 321. The user dials 1 5 5 5 1 2 1 2. The
system finds the first digits in the number dialed match the entry 1 5 5 5 in the Fixed Deny table.
Since extension 101 isn’t allowed toll calls, the call will be restricted (blocked).
