8.1 Getting

Started

8.1.1

Things you need to know before you start using Supplemental

Services.

♦ In North America, Additional Call Offering (ACO) is required on your ISDN line in order to use the

Call Waiting feature. Flexible Calling is required on your ISDN line in order to use the Three-Way-
Calling or Call Transfer features. You need to check with your telephone company to confirm if these
services are available to you and if so, are there any additional charges for them.

♦ In some cases, your telephone company may only enable these features on your first directory (phone)

number. In this case, you may want to request that the features be enabled on your second directory
number as well.

8.2 Setting Up Supplemental Phone Service

All Supplemental Phone Services are enabled by default except for Call Waiting, which is disabled by
default but can be enabled in Menu 2.1- ISDN Advanced Setup. The Calling Line Indication, or Caller
ID, also in this menu decides whether the other party can see your number when you call. If set to Enable
(default), the Prestige sends the caller ID and the party you call can see your number, otherwise if set to
Disable, the caller ID is blocked.

Flashing means to press the hook for a short period of time (a few hundred milliseconds) before releasing it.
On newer telephones, there should be a “flash” key (button) that generates the signal electronically. If the
flash key is not available, you can tap (press and immediately release) the hook by hand to achieve the same

“US” refers to a broad range of switch types supported in the USA.
