Number Manipulation Parameters
Table 21
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'.
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).
The number manipulation can be performed using a combination of each of the above criteria,
or using each criterion independently.
For available notations that represent multiple numbers, see
Num of stripped digits

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 '*' wildcard represents any number
between 0 and 255, for example, 10.8.8.* represents all addresses
between 10.8.8.0 and 10.8.8.255.
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.
A combination of the two options is allowed (for example, 2(3)).
