number "0202158888888". To perform such manipulation, the following configuration is
required in the Number Manipulation table:
1. The following notation is used in the 'Prefix to Add' field:
0[5,3]15
where,
• 0 is the number to add at the beginning of the original destination number.
• [5,3] denotes a string that is located after (and including) the fifth character (i.e.,
the first '2' in the example) of the original destination number, and its length being
three digits (i.e., the area code 202, in the example).
• 15 is the number to add immediately after the string denoted by [5,3] - in other
words, 15 is added after (i.e. to the right of) the digits 202.
2. The first seven digits from the left are removed from the original number, by entering
"7" in the 'Stripped Digits From Left' field.

In this configuration example, the following manipulation process occurs:
1. The prefix is calculated as 020215.
2. The first seven digits from the left are removed from the original number, thereby
changing the number to 8888888.
3. The prefix that was previously calculated is then added.
25.4 SIP Calling Name Manipulations
The calling name manipulation tables let you configure up to 120 manipulation rules for
manipulating the calling name (i.e., caller ID) in SIP messages for IP-to-Tel and Tel-to-IP
calls. Manipulation includes modifying or removing the calling name. For example, assume
that an incoming SIP INVITE message includes the following header:
P-Asserted-Identity: "company:john" sip:6666@78.97.79.104
Using the Calling Name Manipulation for IP-to-Tel Calls table, "company" can be changed
to "worker" in the outgoing INVITE, as shown below:
P-Asserted-Identity: "worker:john" sip:996666@10.13.83.10
The calling name manipulation tables include the following:
 Calling Name Manipulation for IP-to-Tel Calls table
 Calling Name Manipulation for Tel-to-IP Calls table
Configuration of calling name manipulation rules includes two areas:
 Match: Defines the matching characteristics of an 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 calling
