Configuring Multicast
Addresses
The NBX 100 uses IP Multicast addressing to distribute information for
certain system features, including Mapped Line Appearances, Music on
Hold, Internal and External Page, and Conference Calls. These features
are available on Layer 2 and Layer 3 IP devices. The IP implementation
uses IGMP to transmit and distribute the necessary data and audio.
The NBX 100 Internet Gateway Multicasting Protocol (IGMP) is an
implementation of Administratively Scoped IP Multicast that uses three
scopes of administration: Local Scope, Organizational Local Scope, and
Global Scope. Local Scope is limited by local routers: 239.255.0.0/16;
Organizational Local Scope is limited by boundary routers:
239.192.0.0/14; Global Scope: 224.2.0.0 - 224.2.127.253.
IGMP may not be available in all systems or network topologies. All of the
routers between the various components must support IGMP and the
necessary router protocols to establish a path for the IP Multicast packets.
Note that each event that occurs in an IGMP setup, such as taking a
telephone off the hook, causes a packet of 200 to 300 Kb to be sent.
The default settings for the IP Multicast addresses should work in most
network environments. Users who need to modify the addresses can do
so using the
Multicast Addresses
button in the
System Settings
window
to change IGMP addresses when using Standard IP or IP-on-the-fly
network protocols. Certain addresses are reserved.
To configure multicast addresses:

On the System Settings tab (Figure 48), click

Multicast Address List window appears (Figure 54).
