Feature Keys; Class Of Service; Personal Identification Number (Pin); Frequently Used Keys - Siemens 300Series User Manual

Feature Keys

Feature keys give you access to system features such as Hold,
Transfer, Mailbox, and Program. Press the key labeled with the feature
name to gain access to the feature. You can also dial feature access
codes to gain access to features. (See "Feature Access Codes" on page
1-15.)
Note: The labels used in this guide to indicate feature names on keys
are the defaults that come with your system. However, your
system administrator can configure them differently to suit
your company's requirements.

Class of Service

Some of the telephones in your system may be set up to use one class
of service (the primary) during normal business hours and then
automatically change to a more limited one (the secondary) during
non-business hours. If so, the features you can use may vary,
depending on the class of service in effect at the time.

Personal Identification Number (PIN)

A personal identification number (PIN) enables you to use another
telephone within your company to gain access to the features of your
own telephone. You may also need a PIN to be able to dial an outside
number.
Ask your system administrator whether you have been assigned a PIN.

on page 7-12, and "Forced Authorization" on page 7-15.

Frequently Used Keys

extensions that are busy, ringing, or in Do Not Disturb mode. (See

return calls to parties that have left you reminder messages and to the
PhoneMail system. (See "Using Your Mailbox" on page 2-21.)
