Enhanced Local Dialing
The 4610SW/4620/4620SW/4630/4630SW IP Telephones have a variety of telephony-related
applications (e.g., Speed Dial, Call Log, Web Browser, etc.) which may obtain a telephone number during
operation. For example, an incoming Call Log call will obtain the Calling Party Number, while the web
browser may 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 and,
based on administered parameters, 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 the accurate
administration of several important values.
information is expanded upon here.
NOTE:
In all cases, the values to be administered are the values relevant to the location of the
Avaya media server to which the 4610SW/4620/4620SW/4630/4630SW IP Telephones
are registered. Hence, if the telephone was in Japan, but the media server was in the
United States, the value of PHNCC would be properly set to "1".
In all cases, the digits inserted and dialed by the 4610SW/4620/4620SW/4630/4630SW
are subject to standard Avaya media server features and administration such as Class of
Service (COS), Class of Restriction (COR), Automatic Route Selection (ARS), etc.
As indicated in
off the Enhanced Local Dialing feature.
The system values relevant to the Enhanced Dialing Feature are:
•
PHNCC; the international country code for the media server
(e.g., "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 dialed from the media server to access public network international trunks
(e.g., "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 phone number as a link on the Human Resources page. A 4620 user selects that link, the 4620
deduces the phone number is part of the corporate network (because the phone number's length is the
same as the corporate dialing plan), and dials the number without further processing.
Example: A user notes the web site displayed contains an international phone number that needs to be
called and presses "Call." The 4630/4630SW determines the number to be called is from another country
code, and prepends the rest of the phone 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.
