The "Codes and Prefixes" Tab

8.4.2 The "Codes and Prefixes" Tab

Enter the codes, prefixes and public line access prefixes for the location on this tab.

The following parameters determine how Swyx should interpret phone numbers dialed by a user (or a trunk group) at this site.

Example:

A user has the location London (codes 44, 20, prefixes 00, 0, public line access prefix 0). This user is now dialing 0456789. Swyx now interprets the initial "0" as a dial-out prefix and the sequence of digits "456789" as a local number. This results in the canonical number +4420 456789.

Codes and Prefixes

Own country code

Here you define your country code. For the United Kingdom, it is '44’.

Own area code

Enter your area code here without the preceding '0', for example, '20' for London or '161' for Manchester.

Prefix for international calls

The code for international calls is entered in this field. In Germany, this code is '00'.

Prefix for long distance calls

Here you enter the digit(s) which must be dialed in order to make a long distance call. In Germany, the digit required for long distance calls is always '0'.

Phone Numbers in the USA

In the USA, local numbers always consist of 10 digits preceded by the country code for the USA (1):

Own country code: 1

Own area code: The first three digits of the local, ten-digit number

Prefix for international calls: 011

Prefix for long distance calls: 1

Phone Numbers in Switzerland

In Switzerland, a subscriber number always consists of an area code and a subscriber line number.

Therefore, the following general SwyxServer settings must be configured in Swyx Administration:

Own country code: 41

Own area code: according to the local public network without the preceding zero.

Prefix for international calls: 00

Prefix for long distance calls: 0

In Switzerland, it is also important to note that when making outgoing calls—even for local calls—you must always dial the complete number, including the long-distance prefix and the area code. Swyx automatically takes these requirements into account when the user initiates a call using a canonical number (+41...).

Private Branch Exchange related Properties:

Public Line Access

This is the number Swyx users must dial to make external calls. Default value: ‘0’.

You are able to enter several Public Line Accesses separated by a semicolon, e.g. to differentiate private and business calls using a different Public Line Access.

Route undeliverable calls to Internal Number:

If a call is directed to a number which is within the number range of SwyxServer but has not been assigned to a user, this call will be forwarded to the number listed here. You can select the phone number from the list of Swyx numbers. It can also be a number of a connected SwyxServer.

If the number selected here is no longer present, an error message is displayed until you have selected another number for the routing of undeliverable calls. This can be the case, for example, if the number has been deleted, or you have selected the number of a connected server to which there is no longer a connection.
