When a call number could not be matched as a public networknumber, 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 Phone Administration, eachnumber 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 dialled in its simplestform. 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 tothe 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 notcorrespond 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 dialled in their simplestform. Thus a number in the local public network region does not have the region codeprefix. Numbers in the same country but not in the local region are dialled as nationalnumbers. Numbers for a different country are dialled using the international format.• "National public form": All numbers within the current country are dialled as nationalnumbers, thus even local numbers will have a region code prefix (as dialling from amobile). 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 notrequired.• "For external numbers": Default value. All public network numbers will be prefixed withthe 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 accesscode.• International gateway code:> To enable the phone to discern internal numbers from external numbers, it iscrucial that a canonical lookup table is provided (Section 3.13.2, “CanonicalDial Lookup”).
