Table 5-8: 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 5.5.3.1 on page 79.
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)).
Prefix / Suffix to add
• Prefix - Enter the number / string you want to add to the front of the phone
number. For example, if you enter 9 and the phone number is 1234, the new
number is 91234.
• Suffix - Enter the number / string (in brackets) you want to add to the end of the
phone number. For example, if you enter (00) and the phone number is 1234,
the new number is 123400.
Note: You can enter a prefix and a suffix in the same field (e.g., 9(00)).
Number of digits to leave Enter the number of digits that you want to leave from the right.
Note: The manipulation rules are executed in the following order:
1. Num of stripped digits
2. Number of digits to leave
3. Prefix / suffix to add
Figure
5-10 on the previous page exemplifies the use of these manipulation rules in the ‘Source Phone Number
Manipulation Table for TelÆIP Calls’:
• When destination number equals 035000 and source number equals 20155, the source number is changed to
97220155.
• When source number equals 1001876, it is changed to 587623.
• Source number 1234510012001 is changed to 20018.
• Source number 3122 is changed to 2312.
Presentation Select ‘Allowed’ to send Caller ID information when a call is made using these
destination / source prefixes.
Select ‘Restricted’ if you want to restrict Caller ID information for these prefixes.
When set to ‘Not Configured’, the privacy is determined according to the Caller ID
table (refer to Section
5.5.8.3 on page 103).
Note: If ‘Presentation’ is set to ‘Restricted’ and ‘Asserted Identity Mode’ is set to ‘P-
Asserted’, the From header in INVITE message is: From: ‘anonymous’ <sip:
anonymous@anonymous.invalid> and ‘privacy: id’ header is included in the INVITE
message.
