Polycom CMA System Configuration

Configure Redundancy

You can install the CMA 5000 system in a fault-tolerant, high-availability, redundant configuration. The CMA 4000 system is not available in a redundant configuration.

A redundant CMA system configuration requires the installation of two CMA system servers on the same network. During First Time Setup, you are instructed to assign these two servers physical IP addresses. Once the two system servers are installed, see “Polycom CMA System Redundancy” on page 431 to finish implementing redundancy.

Set Up Video Call Routing

The video call routing setup includes the gatekeeper, site topology, gateway and MCU dial plan services, and bandwidth management.

You can perform the following tasks:

•Handle inbound ISDN calls and route them to correct endpoints.

•Enable outbound IP- based calls.

•Connect through a firewall using an SBC device.

•Allow or deny calls to and from unregistered endpoints (rogue calls).

•When you have a third-party MCU that registers with the gatekeeper using standard H.323 protocol, add gateway and MCU dial plan services manually.

•Define new sites and site links.

•Add IP-to-ISDN call routing using least-cost routing.

•Define neighboring gatekeepers.

•Enable routing of H.323 calls to neighboring gatekeepers.

•Define a site for each physical location in which a LAN or an ISDN connection exists. If you use VPN connections, you can consolidate distinct physical locations into a single logical site to simplify management tasks.

•For each site, define the subnets in which the video endpoint systems are deployed. It is important that the IP addresses used by the endpoints belong to only one subnet at a site.

•Define least-cost routing tables only when you use the least-cost routing feature.

•Customize default dialing rules.
