23.2 Configuring Source/Destination Number
Manipulation Rules
You can configure rules for manipulating destination and/or source telephone numbers for
IP-to-Tel and Tel-to-IP calls. The following number manipulation tables are used for this:

Tel-to-IP calls:
•
Destination Phone Number Manipulation Table for Tel > IP Calls table (up to 120
entries)
•
Source Phone Number Manipulation Table for Tel > IP Calls table (up to 120
entries)

IP-to-Tel calls:
•
Destination Phone Number Manipulation Table for IP > Tel Calls table (up to 120
entries)
•
Source Phone Number Manipulation Table for IP > Tel Calls table (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.
