8.2.2 Rate Settings
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:
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 c harged 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 Settings
DMZ is an abbreviation for demilitarized zone. It is a buffer between safe system and unsafe
system to solve the problem that facilities in the outer net access servers behind firewall in the private
network. The buffer is in a small network zone between enterprise internet and outer net where it can
put some servers that must be public, for example Web server, FTP server and so on.
The IP-PBX supports DMZ by cooperating with routers which provides DMZ function.
The DMZ must be set ON if the DMZ of firewall is activated.
