	Table 5-1: Number Manipulation Parameters
Parameter	Description
Destination Prefix	Each entry in the Destination Prefix fields represents a destination telephone number
	prefix. An asterisk (*) represents any number.
Source Prefix	Each entry in the Source Prefix fields represents a source telephone number prefix.
	An asterisk (*) represents any number.
Source IP	Each entry in the Source IP fields represents the source IP address of the call
	(obtained from the Contact header in the Invite message).
	This column only applies to the ‘Destination Phone Number Manipulation Table for IP
	to Tel’.
	Note: The source IP address can include the “x” wildcard to represent single digits.
	For example: 10.8.8.xx represents all the addresses between 10.8.8.10 to 10.8.8.99.

The manipulation rules are applied to any incoming call whose:

• Destination number prefix matches the prefix defined in the ‘Destination Number’ field.

• Source number prefix matches the prefix defined in the ‘Source Prefix’ field.

• Source IP address matches the IP address defined in the ‘Source IP’ field (if applicable).

Note that number manipulation can be performed using a combination of each of the above criteria, or using each criterion independently.

Note: For available notations that represent multiple numbers, refer to Section 5.8.3.1 on page 47.

Num of stripped digits	• Enter the number of digits that you want to remove from the left of the telephone
	number prefix. For example, if you enter 3 and the phone number is 5551234, the
	new phone number is 1234.
	• Enter the number of digits (in brackets) that you want to remove from the right of
	the telephone number prefix.
	Note: A combination of the two options is allowed (e.g., 2(3)).
