This table is designed to ensure the safe use of gateways. Administrators can add the authorized IP
addresses to this table, and the gateways will only process the information from authorized IP addresses.
If the IP table is empty, the gateways will not perform IP address-based message filtering.
For example: the gateway will only process the messages from 202.96.209.133 after adding
202.96.209.133 to its IP table.

Dialing rules are used to effectively judge if the received number sequence is completed, for the purpose
of ending up receiving numbers and sending out the received numbers. The proper use of dialing rules
can help to reduce the connection time of telephone calls.
The maximum number of rules that can be stored in gateways is 520. The total length of dialing rules
table (the total length of all dialing rules) cannot be more than 3000 bytes.
The following provides a description of typical rules:
