About this Guide
The Cisco VG248 Analog Phone Gateway Software Configuration Guide provides the information you need to configure and manage the Cisco VG248 Analog Phone Gateway (VG248) on your network.
Network engineers, system administrators, and telecom engineers should review this guide for information about configuring and using the VG248 in the network.
The tasks described in this guide are considered to be administration-level tasks. Because of the close interaction of the VG248 with Cisco CallManager and analog telephony systems, these tasks require that you are familiar with these systems as well.
This guide provides the required steps to configure and manage the VG248. You must use this guide in conjunction with the Cisco VG248 Analog Phone Gateway Hardware Installation Guide to get the VG248 up and running on your network.
Because of the complexity of an IP telephony network, this guide does not provide detailed information for required procedures performed on other Cisco or third-party devices. Refer to the documentation provided with these systems for installation and configuration instructions.
Table 1 provides an overview of the organization of this guide.
