Feature Phones
A feature phone is a standard phone that has feature buttons in addition to the
regular 12-key dial pad. For example, there are feature phones that have
programmable auto dial buttons, last number redial buttons, hold buttons, and
built-in speakers. Even though some feature phones have buttons like those
provided on system phones, they may not work. Refer to the feature phone’s
documentation for more information on what these phones can do.
Combination Extensions
A combination extension is an extension with two devices connected to
it—either two standard devices, or a system phone and a standard device (but
not two system phones). (Appendix C provides instructions for installing a
combination extension.)
Using the telephones in a combination extension is fairly simple. The main thing
to understand is that the two telephones share a single extension in the same
way that 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). For example:

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. If you prefer not to hear both phones ringing,
turn off the standard phone’s ringer.
If you make a voice-signaled intercom call to a combination extension
with a system phone, the system phone will receive the voice signal; the
standard phone will not ring.
The lights on the system phone show what the standard phone is doing
as well as what the system phone is doing. For an explanation of light
patterns, see “Lights” at the beginning of this chapter.
You can handle a call on the standard phone by pressing buttons on the
system phone. For example, you can use the system phone to select a
specific outside line, and conduct the call on the standard phone. Or, if
you are on a call using the standard telephone, you can put that call on
hold by pressing [
Hold
] on the system phone. To do this, it is not
necessary to lift the handset of the system phone. (Held calls cannot be
retrieved from a standard phone in a combination extension.)
While you are on a call on a standard phone, you can activate calling
features from the system phone
