Feature Phones
A feature phone is a standard phone that has feature buttons in addition to the regular
Combination Extensions
A combination extension is an extension with two devices connected to
The following are examples of useful combination extensions:
■System phone plus standard phone, for power failure backup on extensions 10, 16, 22, 28, 34, 40, 46, and 52
■System phone plus answering machine
■System phone plus fax machine
■System phone plus headset
■System phone plus an external alert (such as a bell or chime).
Using the telephones in a combination extension is fairly simple. The main point to understand is that the two telephones share a single extension in the same way several home telephones share a single line. A system phone works like it always does and a standard phone works like it always does when connected to the system. Only one phone or device can be used at a time, unless you want to join the two on a single call (the same way two people can pick up the same call on different telephones at home). Furthermore:
■Both phones share the same extension number.
■Both phones share the same voicepath; that is, when either phone is busy, the extension is busy.
■Calls ring at both phones.
