24.4 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 272.
The following procedure describes how to configure calling name manipulation rules
through 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: ini file
(CallingNameMapTel2Ip)
Calling Name Manipulation Table for IP-to-Tel Calls table: ini file
(CallingNameMapIp2Tel)
To configure calling name manipulation rules:
1. Open the required calling name manipulations page (Configuration tab > VoIP menu
> Gateway > Manipulations > Calling Name IP->Tel or Calling Name Tel->IP).
