23.4 SIP Calling Name Manipulations
The Calling Name Manipulations Tel2IP and Calling Name Manipulations IP2Tel tables
allow you to configure up to 120 manipulation rules for manipulating the calling name (i.e.,
caller ID) in SIP messages. This can include modifying or removing the calling name. SIP
calling name manipulation is applicable to Tel-to-IP and IP-to-Tel calls.
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 Manipulations IP2Tel 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
The calling name manipulation tables provide two configuration areas:
Matching characteristics (Rule) of incoming call, for example, prefix of destination
number.
Manipulation operation (Action), for example, remove user-defined number of digits
from the left of the calling name.
If the incoming call matches the characteristics of a rule, then its manipulation action is
applied.
Notes:
• For configuring the Calling Name Manipulation Table for Tel > IP Calls table for
retrieving calling name (display name) from an Active Directory using LDAP
queries, see 'Querying the AD for Calling Name' on page 191.
• The Calling Name Manipulations Tel2IP table can also be configured using the
table ini file parameter, CallingNameMapTel2Ip.
• The Calling Name Manipulations IP2Tel table can also be configured using the
table ini file parameter, CallingNameMapIp2Tel.
To configure calling name manipulation rules:
1. Open the required Calling Name Manipulations page (Configuration tab > VoIP menu
> GW and IP to IP submenu > Manipulations > Calling Name IP->Tel or Calling
Name Tel->IP).
2. Click the Add button; the following dialog box appears:
