New Features Overview

Cluster (UCM6304/6308)

Users can expand calling capabilities by pooling resources of up to 5 additional UCMs under the same switch and network segment, allowing the system to handle more calls and meeting participants.

If a UCM6304 acts as the business server with additional UCM6304 and UCM6308 as media servers, the capacity would be:

• Concurrent Calls: 300 (UCM6304 Business Server) + 335 (UCM6304 Media Server) + 390 (UCM6308 Media Server) = 1025
• Meeting Participants: 200 (UCM6304 Business Server) + 250 (UCM6304 Media Server) + 300 (UCM6308 Media Server) = 750

CPU thresholds can be set on each media server to restrict calls based on CPU usage. For example, with a 90% CPU threshold on both media servers:

• Concurrent Calls: 300 + ((335 + 390) * 0.90) = 952
• Meeting Participants: 200 + ((250 + 300) * 0.90) = 695

To create a cluster, assign one UCM as the main Business Server and at least one other UCM as a Media Server. Configure the Business Server via System Settings->Cluster, enabling Media Cluster and selecting 'Business Server' for Device Role.

Figure 1 - Cluster Configuration shows the interface for setting up a cluster.

• Enable Media Cluster: Toggles clustering functionality.
• Device Role: Assigns the role (Business Server or Media Server). Business Server is the main operational server. Media Server is a resource server with PBX features disabled.
• Multicast Network Port: Enter the network port for multicast functionality.
• Multicast IP Address: Enter the multicast IP range (224.0.1.0 - 238.255.255.255).
• Multicast Address Port Start Value: Enter the start port number (1024 - 65535). Must be lower than or equal to the end value.
• Multicast Address Port End Value: Enter the end port number (1024 - 65535). Must be greater than or equal to the start value.
• Business Server Listening Port: Port for the business server to listen for media server information (1024 - 65535).
• Media Server IP: Enter the IP address of the media server (up to 5 can be added).
• Memory Usage Threshold (%): When exceeded, media services transfer to the server with the lowest usage. Service may be temporarily paused.
• CPU Usage Call Control Threshold (%): When exceeded, media services transfer to the server with the lowest usage. Service may be temporarily paused.
• Disk Available Space (MB): If disk space falls below this value, the server will not be used until space is sufficient again.

Multicast Communities

Create and page multiple multicast paging groups simultaneously with the Multicast Communities feature. This is useful for large-scale, segmented announcements across sites or companies without needing to create new paging groups and configure endpoints individually.

Figure 3 - Multicast Community Overview and Figure 4 - Multicast Community Settings illustrate the configuration of multicast communities.

PMS Billing

UCM now includes billing functionality for PMS integration, including its own Local PMS. Call rates can be set for outside call billing.

Figure 5 - Local PMS Billing and Figure 6 - Call Rate Overview show the PMS billing setup.

Figure 7 - Call Rate Options details how to set call rates. For example, calls starting with '1' using USD currency have a base cost of $5 for the first 60 seconds, with an additional $2 for every subsequent 60 seconds.

Considerations for analog trunks:

• If Polarity Reversal is enabled, the call is charged upon establishment/answer.
• If Polarity Reversal is disabled, the call is charged when it leaves the UCM.

New HTTPS API Commands: Room Status & Minibar Status

The following API commands have been added:

• getMiniBar: Retrieves information about the configured minibar.
• listMiniBarGoods: Retrieves the list of purchasable items.
• listPMSRoom: Retrieves a list of all rooms.
• getPMSRoomGoods: Retrieves the status of purchasable minibar items in a specified room.

Example requests and responses for these commands are provided, detailing parameters such as status, extension, goods_name, and tax.
