Business Communications Manager system configuration
Several sections of the Business Communications Manager must be properly configured prior to
activation of IP telephony.
Answer the questions in Table 6 to determine if your Business Communications Manager has been
correctly configured.
Table 6 Business Communications Manager system configuration
Defining published IP address
The published IP address is the IP address used by computers on the public network to find the
Business Communications Manager. For example, if a Business Communications Manager has a
LAN interface (LAN1) that is connected only to local office IP terminals and a WAN interface
(WAN1) that is connected to the public network, then WAN1 should be set to the published IP
address.
Setting the Global IP (published IP)
To set the published IP address:
1 In Unified Manager, open Services and click on IP Telephony.
The Global settings tab appears. Refer to Figure 2.
2 From the Published Address menu, select the appropriate network interface.
