Initial extension digits

Initial digits
: List of initial digits of all possible extensions in the
local enterprise network. When a call number could not be matched as a public network
number, the phone checks if it is part of the local enterprise network. This is done by com-
paring the first digit of the call number to the value(s) given here. If it matches, the call num-
ber is recognized as a local enterprise number and processed accordingly.
If, for instance, the extensions 3000-5999 are configured in the OpenScape Desk Phone
IP, each number will start with 3, 4, or 5. Therefore, the digits to be entered are 3, 4, 5.

Internal numbers
•
"Local enterprise form": Default value. Any extension number is dialed in its simplest
form. For an extension on the local enterprise node, the node ID is omitted. If the ex-
tension is on a different enterprise node, then the appropriate node ID is prefixed to
the extension number. Numbers that do not correspond to an enterprise node exten-
sion are treated as external numbers.
•
"Always add node": Numbers that correspond to an enterprise node extension are al-
ways prefixed with the node ID, even those on the local node. Numbers that do not cor-
respond to an enterprise node extension are treated as external numbers.
•
"Use external numbers": All numbers are dialled using the external number form.
•
External numbers
•
"Local public form": Default value. All external numbers are dialed in their simplest
form. Thus a number in the local public network region does not have the region code
prefix. Numbers in the same country but not in the local region are dialled as national
numbers. Numbers for a different country are dialled using the international format.
•
"National public form": All numbers within the current country are dialled as national
numbers, thus even local numbers will have a region code prefix (as dialling from a mo-
bile). Numbers for a different country are dialled using the international format.
•
"International form": All numbers are dialled using their full international number for-
mat.
•
External access code
•
"Not required": The access code to allow a public network number to be dialled is not
required.
•
"For external numbers": Default value. All public network numbers will be prefixed with
the access code that allows a number a call to be routed outside the enterprise net-
work. However, international numbers that use the + prefix will not be given access
code.

To enable the phone to discern internal numbers from external numbers, it is
crucial that a canonical lookup table is provided (Section 3.6.1, “Canonical Di-
aling Configuration”).
