Short numbers can be:
1. Common, which means that all extensions can use them.
2. Individual, which means that they are programmed and used by each extension separately
(10 numbers). See section ”Abbreviated numbers”.
ACCOUNT NUMBER To place costs for external calls on a selected account number (up to 15 digits).
See section ”Other useful facilities”.

options which can be chosen. Voice instructions lead the caller to the desired
destination. See section ”Other useful facilities”.

(extension, common abbreviated number or the operator). There are three possibilities:
1. Direct, which means that all calls to an extension are forwarded directly. 2. On no reply,
which means that a call is forwarded if it is not answered within a certain time. 3. On
busy, which means that a call is forwarded if the extension is busy.
See section ”Call forwarding”.
DIVERSION BYPASS This is useful for letting urgent calls through to an extension where diversion is active.
See section ”Call forwarding”.

If your telephone is equipped with a display, you can see your number.

a pre-programmed phone number will be dialled or function will be executed.

1. Pre-programmed text information. 2. Voice
information.
INTRUSION To intrude on an ongoing call when a requested extension is busy.
See section ”Outgoing calls”.
IP CALL Internal call sent via an internal data network (LAN or WAN).
