This option is only used with systems set to PBX mode. It sets the digit which, when dialed at the start of a number, indicates that the call is intended to be external. The options are to use 0, 9 or no prefix.

Note that the setting also changes the digits used for calls to the first extension on the system. Normally, in addition to the extension's extension number, the number 0 can be used to call that extension. If the number 0 is set as the outside line prefix, the number 9 is used for the first extension.

Setting the System's Outside Line Prefix

1.Click on System in the menu bar.

2.In the System Parameters, set the Outside Line setting to the required option.

•9 (Operator is 0)

•None
No prefix is used for external calls. Any dialing that does not match an internal dial plan number is assumed to be an external call. This is the default setting for systems with the Country setting other then Germany or United States. The digit 0 is used for calls to the operator extension (the first extension in the system).

•0 (Operator is 9)
The prefix 0 is used for external calls. The digit 9 is used for calls to the operator extension (the first extension in the system). This is the default setting for systems with the Country setting Germany.
