feature codes. It also assumes that you have full access to all features and the public phone network.

Ring Back

following:
1. When you call an extension that does not answer or is busy, press
that extension.
When the extension you called becomes free, your phone rings (a burst of three rings).
2. Lift the handset and the extension is called automatically.
When the extension you called is free, your phone rings (a burst of three rings).

Call Waiting

Call Waiting tells you if another call arrives while you are already making a call by providing call waiting
tone. If you hear the call waiting tone, either end your current call or put the caller on hold. The waiting
call should then ring.
To turn call waiting on, dial *15. To turn it off, dial *16.
