Chapter 8, IVS Support for CLASS Features

IVS Support for Anonymous Call Rejection

IVS can support the Anonymous Call Rejection CLASS feature. When a user activates

Anonymous Call Rejection, the system blocks any incoming calls for which the calling

party number is "private." Callers who have blocked their numbers from Caller ID will

hear an announcement that the user does not accept anonymous calls. The announcement

recommends that the caller remove blocking and call back. When the system blocks an

anonymous call, the user’s phone does not ring. The system accepts calls that present a

calling party number or have an unavailable calling party number (for reasons other than

blocking). For such calls, the user’s phone rings.

IVS Support for Automatic Recall

IVS can support the Automatic Recall CLASS feature. With Automatic Recall, a user can

(by pressing *69) automatically redial the last incoming number without having to know

the calling party number of that call. When Automatic Recall requires confirmation, the

system can speak the caller's number. When Automatic Recall lacks confirmation, the

system cannot speak the caller's number.

IVS Support for Remote CLASS Feature Access

IVS can support the Remote CLASS Feature Access capability. This CLASS feature

allows a user to access the following CLASS features from a line other than their primary

line:

• CLASS Service Call Forward

• Anonymous Call Rejection

• Selective Call Forwarding

With IVS support, the Remote CLASS Feature Access capability generates audible voice

prompts for the user during the activation process.

IVS Support for Caller Identification with Name and Number

IVS can support the Type II Analog Caller Name and Number Delivery feature. This

CLASS feature provides Caller Identification (Caller ID), when the IVC card supports a

Frequency Shift Keying (FSK) application.

To support this CLASS feature, PointSpan must include the PRI ANI application with

name and number calling party identification (CPID) enabled for analog and digital

trunk-to-station and station-to-trunk calls. This feature applies for station-to-station,

station-to-trunk, and trunk-to-trunk calls. It works on both analog and digital stations.
