Network devices

The following table contains questions about devices on the network such as firewalls, NAT

devices, and DHCP servers.

• If the network uses public IP addresses, complete 2.d.

• If the network uses private IP addresses, complete 2.e. to 2.f.

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.

Table 2 Network device checklist

Prerequisites Yes No

2.a Is the network using DHCP?

2.b If so, are you using the DHCP server on the Business Communications

Manager?

2.c Is the network using private IP addresses?

2.d Are there enough public IP addresses to accommodate all IP telephones and the

Business Communications Manager?

2.e Does the system have a firewall/NAT device, or will the Business

Communications Manager be used as a firewall/NAT device?

NOTE: NetVision handsets do not work on a network that has NAT between the handset

and the system.

2.f If the Business Communications Manager is to be used as a firewall/NAT device,

do the firewall rules fit within the 32 input rules and 32 output rules that the

Business Communications Manager provides?

2.g A hub-based core will not have suitable performance for IP Telephony. Does the

network use a non-hub solution at its core?
