Enhanced Local Dialing

The 4610SW, 4620/4620SW, 4621SW, 4622SW, 4625SW, and 4630/4630SW have a variety of telephony-related applications (e.g., Speed Dial, Call Log, Web Browser, etc.). These applications might obtain a telephone number during operation. For example, the Call Log saves an incoming caller’s number, while the Web browser might obtain a dialable link from a corporate Web site. Before Release 1.8 software, when the user indicated a desire to call one of these incoming numbers, the 4610SW/4620/4620SW/4630/4630SW would first require the user to edit the number, generally by prepending digits to account for dial access codes, country codes if applicable, etc.

As of Release 1.8, the 4610SW/4620/4620SW/4630/4630SW can evaluate a raw telephone number. This is also true of the 4621SW, 4622SW, and 4625SW as of Release 2.2. Based on administered parameters, the telephone can automatically prepend the correct digits, saving the user time and effort. This is the “Enhanced Dialing” feature. The key to this feature’s success is accurate administration of several important values. Table 12 summarizes these values and their meanings. That information is expanded upon in this section.

NOTE: In all cases, the values you administer are the values relevant to the Avaya Media Server’s location at which the IP telephones are registered. If a telephone is in Japan, but its media server is in the United States, set the PHNCC value to “1" for the United States.

In all cases, the digits the phones insert and dial are subject to standard Avaya Media Server features and administration. This includes Class of Service (COS), Class of Restriction (COR), Automatic Route Selection (ARS), etc.

As indicated in Table 10, you can administer the system parameter ENHDIALSTAT to turn off the Enhanced Local Dialing feature.

The system values relevant to the Enhanced Dialing Feature are:

• PHNCC - the media server’s international country code.
  For example, “1” for the United States, “44” for the United Kingdom, etc.
• PHNDPLENGTH - the length of the dial plan on the media server.
• PHNIC - the digits the media server dials to access public network international trunks.
  For example, “011” for the United States.
• PHNLD - the digit dialed to access public network long distance trunks on the media server.
• PHNLDLENGTH - the maximum length, in digits, of the national telephone number for the country in which the Avaya Media Server is located.
• PHNOL - the character(s) dialed to access public network local trunks on the media server.

Example: A corporate voice network has a 4-digit dialing plan. The corporate WML Web site lists a 4-digit telephone number as a link on the Human Resources page. A 4620 user selects that link. The 4620 deduces the telephone number is part of the corporate network because the telephone number’s length is the same as the corporate dialing plan. The telephone dials the number without further processing.

Example: A user notes a Web site contains an international telephone number that needs to be called, and presses “Call.” The 4630/4630SW determines the number to be called is from another country code. The telephone then prepends the rest of the telephone number with PHNOL to get an outside line + PHNIC to get an international trunk. The 4630/4630SW then dials normally, with the Avaya Media Server routing the call appropriately.

NOTE: The Enhanced Local Dialing algorithm requires that telephone numbers be presented in a standard format. The standard format depends on how you administer the parameters indicated in Table 12. The algorithm also assumes that international telephone numbers are identified as such in, for example, WML Web sites. This is indicated by preceding that type of number with a plus (+) sign, and a space or some non-digit character following the country code.
