Feature Access Codes
Since a set of features has already been assigned to
your telephone's feature keys, you may find that your
telephone does not have feature keys for some of the
features described in this guide. However, you can
still use any of these features that are available on
your system and permitted by your class of service by
dialing that feature's access code, if it has one.
Throughout the remainder of this guide, the steps de-
scribed for using each of the system features include
the feature key you press to access a feature and the
feature code you can dial if you do not have that fea-
ture key. If you need to know a particular feature
access code in a hurry, see "Feature Access Codes" on
page A–1, which lists these codes alphabetically.
Note
You must have a dial tone before entering a feature
access code. If you do not have a dial tone, press the
Transfer key to get one.
The feature access codes listed in this guide are the
defaults that come with your system. However, your
CBX system administrator can configure them
differently to suit your company's requirements.
