This parameter is useful in such cases where a call manager will intentionally modify the display name according to a
specific scenario. For example, if a Manager forwards an incoming call to an employee, the call manager may modify the
display name to state “--> [Manager’s Name] Caller’s Name”. With the “directory lookup suppression pattern” parame-
ter configured for “-->” pattern matching, the IP phone will bypass the local directory lookup and the phone’s screen will
display the call as intended by the call manager.
Pattern Rules and Syntax
The customized display name must start with the pattern. The patterns that can be configured include the following reg-
ular expressions:
• “-->x+”
• “==>x+”
• “@@@x+”
• “aaax+”
Additionally, the pattern syntax supports the regular expression | to specify multiple OR combined patterns (e.g. “--
>x+|==>x+|aaax+”).
Configuring the Display Name Customization Feature
Use the following procedures to configure the display name customization feature.
Notes:
• Pattern matching is only applied for incoming calls and against the From header display name for incoming calls.
• Pattern matching is applied to shared lines.
• Pattern matching is not applied against the display name in the P-Asserted-Identity (PAI) header.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section, “Display Name Customization Settings” on pageA-133.
