8.2.2 Rate Setting
Rate setting is used to calculate the charges for each call. The IP PBX will generate a call record for
the charges. All the charges are based on this rate table.
The rate is based on the prefix to calculate the charges:
Example:
Prefix: 0
Rate: 15 (cent)
Time Unit： 60 (second)
This means when calling a number with 0 prefix (e.g., 01010086), the rate is 15 cents for every 60
seconds, and the duration less than 60 seconds will be charged the same as 60 seconds. In addition,
the prefix is for the longer one. For example, if there are rates for prefixes 0 and 00, the call number
with 00 prefix will be charged per the rate of 00 instead 0.
If there is no rate for the calling prefix, this implies the rate is 0.
8.2.3 DMZ
DMZ (DeMilitarized Zone) is used to send all the non-authorized incoming packets to the DMZ.
The DMZ must be set ON if the DMZ of firewall is activated.
