Cisco VG248 Analog Phone Gateway Software Configuration Guide

OL-1209-02

1

Overview

The Cisco VG248 Analog Phone Gateway (VG248) enables you to integrate
analog telephones, modems, and fax machines with the Cisco CallManager IP
telephony system. You can also integrate legacy voice mail and PBX systems with
Cisco CallManager using Simplified Message Desk Interface (SMDI).

The following topics provide an overview of the supported features and analog
devices and describe the supported data and voice protocols:

•

Understanding How the VG248 Integrates with the Cisco IP Telephony
Network, page 1-2

•

Understanding How the VG248 Supports Telephony Features, page 1-3

•

Supported Analog Devices, page 1-8

•

Supported Protocols, page 1-10

For details on using SMDI to integrate your existing voice mail systems with
Cisco CallManager see the

Chapter 5, “Integrating Cisco CallManager with

Voice Mail Systems Using SMDI.”
