Polycom CMA System Configuration

Polycom, Inc.

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 

page 431 to finish implementing redundancy.

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.
