Initiating a call to a pre-programmed number by dialling a code or pressing a key.
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".
To place costs for external calls on a selected account number (up to 15 digits).
See section "Other useful facilities".
A facility which sends voice instructions to internal and external callers, providing all
options which can be chosen. Voice instructions lead the caller to the desired
destination. See section "Other useful facilities".
An indication to a busy extension, to inform the person that you want to speak to
him/her. See sections "Internal messages" and "Outgoing calls".

numbers) can be stored on each extension. See section "Abbreviated numbers".

If you are working externally, the DISA function enables you to make external calls
(long distance) via the company PBX. You only pay for the call to your company.
See section "Other useful facilities".
Incoming calls to an extension are diverted to another directory number
(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".
This is useful for letting urgent calls through to an extension where diversion is active.
See section "Call forwarding".
All telephones connected to the PBX have a unique internal number (upto 3 digits).
Internal callers are informed about absence and time of return.
External callers are diverted to the operator, where the same information is available.
Information can be of two kinds: 1. Pre-programmed text information. 2. Voice
information.
To intrude on an ongoing call when a requested extension is busy.
See section "Outgoing calls".
Internal call sent via an internal data network (LAN or WAN).
A function that automatically selects the cheapest way to connect your external call
(not necessarily the shortest distance). See section "Least cost routing".
The mailbox system controls the messages that are left for or sent by you when you are
absent. See section "Mailbox system".
