IP Telephony Configuration Guide

Chapter 2

Prerequisites checklist

Before you set up VoIP trunks or IP telephones on a Business Communications Manager,

complete the following checklists to ensure that the system is correctly set up. Some questions do

not apply to all installations.

This guide contains a number of appendices that explain various aspects of the system directly

related to IP telephony functions. However, refer to the Programming Operations Guide for

specific information about configuring the data portion of the Business Communications Manager.

This section includes the following checklists:

• “Network diagram” on page 29

• “Network devices” on page 30

• “Network assessment” on page 30

• “Resource assessment” on page 31

• “Keycodes” on page 31

• “System configuration for IP functions” on page 32

• “VoIP trunks” on page 36

• “Configuring media gateway parameters for IP service” on page 35

Network diagram

To aid in installation, a Network Diagram provides a basic understanding of how the network is

configured. Before you install IP functionality, create a network diagram that captures all of the

information described in the following table. If you are configuring IP telephones but not voice

over IP (VoIP) trunks, you do not need to answer the last two questions.

Table 1 Network diagram prerequisites

Prerequisites Yes

1.a Has a network diagram been developed?

1.b Does the network diagram contain any routers, switches or bridges with corresponding

IP addresses and bandwidth values for WAN or LAN links?

Also refer to Appendix D, “Interoperability,” on page 169.

1.c Does the network diagram contain IP Addresses, netmasks, and network locations of all Business

Communications Managers?

1.d Answer this if your system will use IP trunks, otherwise, leave it blank: Does the network diagram

contain IP Addresses and netmasks of any other VoIP gateways that you need to connect to?

1.e Answer this only if your system will use a gatekeeper, otherwise, leave it blank: Does the network

diagram contain the IP address for any Gatekeeper that may be used?

Note: If the network has a Meridian 1 running IPT software, you cannot use a RadVision gatekeeper.
