3-16 Long-Distance Control Table

This table controls the level of authority of an outgoing (transit out) call that is dialed through FXO and
diverted to PSTN, as below:
Descriptions:
Digit strings in this table are prefixes that the gateway will check on dialed numbers in transit out calls.
This table is used to prohibit dialing any numbers started with specified prefixes.
If Level 0 (the highest level) is set to prohibit dialing any number started with prefix 0204, then any
level below 0 (including Levels 1 to 5) are also prohibited.
If Level 1 is set to prohibit dialing any number with prefix 0, then any level below 1 (including Levels 2
to 5) are also prohibited. Since Level 0 is not restricted to any prefix, therefore at level 0 users can dial
a number with the prefix 0.
Principle: Downward Restriction —If users at a higher level cannot dial a number with a certain prefix,
then users at lower levels also cannot dial a number with the same prefix.
