SIP Calling Name Manipulations

The calling name manipulation tables lets 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. The calling name
manipulation tables include the following:

Calling Name Manipulation Table for IP-to-Tel Calls table

Calling Name Manipulation Table for Tel-to-IP Calls table
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 Table for IP-to-Tel table, the text "company" can be
changed to "worker" in the outgoing INVITE, as shown below:
P-Asserted-Identity: "worker:john" sip:996666@10.13.83.10
Configuration of calling name manipulation rules includes two areas:

Rule: 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
name).
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.
Note: For using the Calling Name Manipulation Table for Tel-to-IP Calls table for
retrieving the calling name (display name) from an Active Directory using LDAP
queries, see Querying the AD for Calling Name on page 224.
The following procedure describes how to configure calling name manipulation rules in the
Web interface. You can also configure these rules using the the following management
tools:

Calling Name Manipulation Table for Tel-to-IP Calls table: table ini file parameter,
CallingNameMapTel2Ip or CLI command, configure voip/gw manipulations calling-
name-map-tel2ip

Calling Name Manipulation Table for IP-to-Tel Calls table: table ini file parameter,
CallingNameMapIp2Tel or CLI command, configure voip/gw manipulations calling-
name-map-ip2tel
