102 Bandwidth Management
2. Branch office (MG 1000B and SRG) Call Servers must be configured
with the same VPNI as that of the main office Call Server with which
they register.
3. Nor tel recommends that all the endpoints on a Call Server (IP Phones
and VoiceGateway Media Cards) be configured with the same Zone
number.
4. Vir tual Trunksmust be configured with a different Zone number than
the endpoints.
Network Planning
Before configuring Bandwidth Management in a CS 1000 network, follow
these steps:
Step Action
1Choose unique VPNI for all Call Servers in the network.
2Choose unique Bandwidth Zone numbers for all Call Servers in
the network. These are used when configuring the endpoints
(telephones and gateways) on the Call Server.
3Choose unique Bandwidth Zone numbers for the Virtual Trunks in
the network.
4Choose the codecs that will be enabled on each CallSer ver.
5Identify what the interzone codec strategy will be (BB-Best
Bandwidth or BQ-Best Quality) for each zone in the network.
6Identify what the intrazone codec strategy will be (BB-Best
Bandwidth or BQ-Best Quality) for each zone in the network.
7Calculate the bandwidth available for intrazonecalls for each zone
in the network.
8Calculate the bandwidth available for interzonecalls foreach zone
in the network.
9Calculate the bandwidth available forintrazone calls

Enabling codecs
In Element Manager, select the codecs that will be enabledfor calls on the
Call Server, and define the associated parameters, such as payload size.
