As well as accessing specific features on your phone, you can access a number of system features by
dialling short codes.
These instructions are for the system's default configuration. They assume that you are using the default
feature codes. It also assumes that you have full access to all features and the public phone network.
Making Calls

When Free) under a dial pad digit, you can:

When you call an extension that does not answer or is busy, press RBak to set a callback on
that extension. When the extension you called becomes free, your phone will ring (a burst of
three rings).

Lift the handset and the extension is called automatically. When the extension you called is free,
your phone will ring (a burst of three rings).

Lift the handset and the extension is called automatically.
To make external calls:
Either:

Dial the number (prefixed by the access code if required).
or

If you hear busy tone while dialling, then the call may be barred. Your system administrator can bar
certain calls, such as those to premium rate numbers and international calls.
