Introduction

There are a number of security issues vis-a-vis Call Vectoring that should be noted. For example, Call Vectoring and Call Prompting can be used to help prevent unauthorized users from gaining access to the switch via the Remote Access feature. This appendix explains how this is done.

Remote Access

Abuse of remote access on the switch is one of the main methods by which unauthorized users obtain telephone services illegally. This section explains how a number of Call Vectoring features can be used to prevent unauthorized use of the DEFINITY remote access feature. No new development is required for any of these services.

Two methods are available, as follows:

■Front-ending remote access (that is, reaching the remote access extension via Call Vectoring)

■Replacing the function of the remote access extension by one or more call vectors.
