Setting the Date and Time on SIP IP Telephones
Issue 6 February 2007 113
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:
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.
Setting the Date and Time on SIP IP Telephones
SIP IP telephones need a source of date and time information. This typically comes from a
network time server running the Simple Network Time Protocol (SNTP). The telephones use
several administrative parameters for this functionality. The parameter SNTPSRVR defines the
server’s IP Address(es). GMTOFFSET defines the offset from Greenwich Mean Time (GMT).
DSTSTART and DSTSTOP define the start and end of Daylight Savings Time, respectively.
DSTOFFSET defines the Daylight Savings Time offset from Standard Time. Finally,
DATETIMEFORMAT defines the format of the date and time display. See Table 10
for
definitions and valid values for SIP Date and Time parameters.
Setting the Dial Plan on SIP IP Telephones
A dial plan is used during manual dialing to allow a call to be initiated without using a Send
button and without waiting for the expiration of a timeout interval. The dial plan consists of one
or more format strings separated by the logical OR symbol ( I ). When the dialed digits match a
format string in the dial plan, the call is initiated. The DIALPLAN parameter defines the dial plan.
Valid characters in a format string, and their meanings, are as follows:
digits 0 through 9, inclusive = Specific dialpad digits
* = the dialpad character *
# = the dialpad character # (but only if it is the first character in the dialed string – see below)
