23 Manipulation
This section describes the configuration of various manipulation processes.
23.1 Configuring General Settings

Figure 23-1: General Settings Page
2. Configure the parameters as required.
3. Click Submit .
23.2 Configuring Source/Destination Number
Manipulation Rules
The number manipulation tables let you configure rules for manipulating source and
destination telephone numbers for IP-to-Tel and Tel-to-IP calls. The number manipulation
tables include the following:

Tel-to-IP calls:
•
Source Phone Number Manipulation Table for Tel > IP Calls (up to 120 entries)
•
Destination Phone Number Manipulation Table for Tel > IP Calls (up to 120
entries)

IP-to-Tel calls:
•
Source Phone Number Manipulation Table for IP > Tel Calls (up to 120 entries)
•
Destination Phone Number Manipulation Table for IP > Tel Calls (up to 120
entries)
Configuration of number manipulation rules includes two areas:

Rule: Defines the matching characteristics of the incoming call (e.g., prefix of
destination number).

Action: Defines the action that is done if the incoming call matches the characteristics
of the rule (e.g., removes a user-defined number of digits from the left of the number).
The device searches the table from top to bottom for the first rule that matches the
characteristics of the incoming call. If it finds a matching rule, it applies the manipulation
configured for that rule. In other words, a rule at the top of the table takes precedence over
a rule defined lower down in the table. Therefore, define more specific rules above more
generic rules. For example, if you configure the source prefix number as "551" for rule
index 1 and "55" for rule index 2, the device uses rule index 1 for numbers that start with
551 and uses rule index 2 for numbers that start with 550, 552, 553, and so on until 559.
However, if you configure the source prefix number as "55" for rule index 1 and "551" for
rule index 2, the device applies rule index 1 to all numbers that start with 55, including
