Interacting with the Phone
6.1 Call Appearances
The ZIP2 has two call appearances. The number of call appearances on a phone indicates the
number of voice calls that the phone can handle. Each call can be individually originated or
received by the phone. The person using the phone can choose to toggle between the calls or
place both calls into a three-way conference.
This type of phone is different from phones that have been in common use for the past 100 years.
On those older phones a physical pair (or two pairs) of wires carry a single voice call. A phone that
can accommodate two voice calls connects to two such circuits, with each circuit referred to as a
line. A switch on the phone selects between the lines (and therefore with whom you are talking).
The ZIP2 has a single circuit to connect to the switch. All calls take place over this same circuit, or
line. Dedicated software and hardware inside the phone and the switch permit you to have two
simultaneous conversations. These are referred to as two calls, not two lines.
6.1.1 First Call Appearance
When you pick up the handset on an idle ZIP2 and make a call, you are using the first call
appearance. When an idle phone rings, the incoming call occupies the first call appearance.
6.1.2 Second Call Appearance
When you make a new call during an existing call, the new call uses the second call appearance.
You must put the first call appearance on hold before you can make the second call. You cannot
make any more calls when both call appearances are in use.
When you are on a call and the phone receives another call, the second call uses the second call
appearance. The phone can receive no other call when both call appearances are in use.
6.2 Using the Keypad
The term keypad refers to the numeral and special purpose keys shown in figure 6-1.
6.2.1 Numeral Keys
The twelve numeral keys are labelled 0 to 9, *, and #. These keys are used for dialling phone
numbers. Several numeral keys, when part of a combination keystroke, perform other phone
functions. These functions are identified by the text next to the key.
