System Features System Features
As well as your phones specific features, you can access a number of system features by dialing 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 telephone network.
Making Calls
Internal Calls:
If your System Administrator has allocated you the Ring Back When Free feature (see RBak+ - Ringback
When Free) under a dial pad digit, you can:
1. When you call an extension that does not answer or is busy, press the RBak feature key to
set a callback on that extension.
2. When the extension you called becomes free, your phone will ring (a burst of three rings).
3. Lift the handset and the extension is called automatically.
4. When the extension you called is free, your phone will ring (a burst of three rings).
5. Lift the handset and the extension is called automatically.
External calls:
To make an external call, either dial the number (prefixed by the access code if required) or use a speed
dial code (contact your system manager for a list of your speed codes).
If you hear busy tone while dialing, then the call may be barred. Your system manager can bar certain
calls, such as those to premium rate numbers and international calls.
Answering Calls
Ringing at your own extension:
Simply pick up the handset. When in headset mode, press the button associated with the alerting call.
The default ringing cadences are:
• Internal calls have a single ring cadence
• External calls have a double ring cadence.
These can be changed by your System Administrator.
Ringing at another extension:
You can answer from your own phone by using Call Pick-Up; lift your handset and dial:
• *30 to answer a call ringing anywhere.
• *31 to answer a call within your group.
• *32*201# to answer the call for a particular extension, in this example 201.
Note: If your phone rings for any longer than a specified period (15 seconds in default), any re-direction
feature that you have activated, such as voicemail or call forwarding, will come into effect.
