Chapter 5 LDAP/CSV Directory ConfigurationAdding Dialing Rules66 Application Gateway Administration GuideAdding Dialing RulesBy default, the full telephone number that is stored in a directory is dialedwhen the IP telephone user selects a number in Express Directory orVisual Voicemail. You can customize telephone numbers as follows:• You can specify the number of digits to be dialed. For example, youcan specify that only the last four digits of numbers beginning with"423500" should be dialed. In that case, if the number in the directoryis 423-500-0987, the Voice Office application will dial 0987.• You can specify the prefixes to be dialed with all numbers that are 3 to5 digits, 6 to 7 digits, and 8 or more digits (as stored in the sourcedirectory).Dialing rules apply to all configured directories. You can alternativelyspecify a prefix for each directory source, as described in “SpecifyingLDAP Attributes for Voice Office Operations,” page 57.The prefix specified in a dialing rule will precede the prefix specifiedfor a directory. For example, suppose that you have two directories, Aand B. A call to directory A requires the prefix “5” and a call todirectory B requires the prefix “6”. All calls require a “9” to be dialedfirst, so the dialing rule specified on the IP Phone page is “9”. Thus,the number dialed for a call to directory A would be “95number” andthe number dialed for a call to directory B would be “96number”.Dialing rules are used by the Application Gateway when it looks up LDAPinformation for Zone Paging and Broadcast Server. The ApplicationGateway reconstructs the full number from the extension and the dialingrules and then looks up the department for Zone Paging and thedepartment and user name for Broadcast Server.To add dialing rules:1 Go to the Operation > Voice Office > IP Phone page.2 If your telephone system does not need to dial the full telephone numberthat is stored in a directory (perhaps for internal extensions), specify howthe number should be trimmed.
