8 Viewing VSM topologies
A VSM topology displays logical connections between a VCX/NBX device and IP phones and physical
connections among IP phones.
VSM topologies are divided into the following types:
• Voice region topology—Logical connections between the region and branch servers on the VoIP
network.
• Voice device topology—Logical connections between a VCX/NBX device and IP phones.
For information about basic operations and functions of topologies, see HP IMC Base Platform
Administrator Guide.
To use the VSM topologies, follow these guidelines:
• You cannot select more than 10 IP phones to view their physical topology.
• Make sure all network devices that IP phones are connected to are added to the IMC Platform.
Otherwise, the physical topology of IP phones cannot be correctly generated.
• If the devices that are directly connected to an IP phone are not added to the IMC Platform, the
right-click menu of the IP phone does not include the View alarms from directly connected devices
option.
• Physical topologies of IP phones are snapshots that do not automatically update after they are
generated.
• In IE, you cannot open multiple physical typologies for IP phones at the same time.
Viewing a voice region topology
In a VoIP network, each VCX server is treated as a site. VoIP networks include the following types,
depending on the number of VCX servers deployed on the network:
• Single site system—The VoIP network uses only one VCX server to provide all voice services.
• Multi-site system—The voice services are provided by multiple VCX servers on the VoIP network.
The server type in a multiple-site system can be "region" or "branch." A region server manages one
or more branch servers. When a branch server fails, the region server provides the call processing
service in place of that branch server.
A voice region topology displays the logical connection between the region server and branch servers
in a VoIP network.
