Organizing Network Components › Call Servers and Call Server Groups

Call Servers and Call Server Groups

Unified communications deployments rely on specialized server hardware or software to route calls, log quality data, and inventory registered endpoints An endpoint is any device where a media stream begins or ends, such as telephone, softphone, telepresence, voice gateway, media device, and video camera.. No matter which physical server performs the main call processing tasks in a system, UC Monitor labels it a call server.

UC Monitor automatically discovers call servers from monitored call traffic. However, many servers can take on the call server role in a multi-vendor environment. Therefore, you can also manually supply information to identify the call servers in your network.

Note: You cannot change the automatic group assignment for Microsoft call servers that belong to pools.

With UC Monitor, you can organize your call servers into call server groups, which mimic the clusters or server pools in your VoIP system. These groups are useful for the following purposes:

• Identifying call server clusters or pools in reports.
• Identifying call servers and call server groups in CA Performance Center when UC Monitor is registered as a data source.
• Helping you to understand call volumes as reported in the Capacity Planning reports.
• Creating valid permission groups so that UC Monitor operators can see the report data in CA Performance Center.
• Letting you assign call server group thresholds to enable incident creation (Cisco only).

Note: Call server group thresholds are assigned only to call servers that are identified as a group. You create call server groups in the management console. You perform most other tasks for organizing items in groups in CA Performance Center.
