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 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:
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 the calling name (display name) from an Active
Directory using LDAP queries, see 'Querying the AD for Calling Name'
on page 194.
• The Calling Name Manipulations Tel2IP table can also be configured
using the table ini file parameter, CallingNameMapTel2Ip or CLI
command, configure voip/gw manipulations calling-name-map-tel2ip.
• The Calling Name Manipulations IP2Tel table can also be configured
using the table ini file parameter, CallingNameMapIp2Tel or CLI
command, configure voip/gw manipulations calling-name-map-ip2tel.
