The Avaya Aura Communication Manager is a core component of the Avaya UC platform and the foundation for delivering real-time voice, video, messaging, mobility and other UC services.

The Communication Manager registers and maintains all Session Initiation Protocol (SIP) endpoints, call routing, call queuing, prioritization of voice and video calls and much more. The product also has built-in conferencing and contact center applications — suitable for companies with call centers and demanding conferencing needs.

The Communication Manager offers more than 700 features that are available to all users, no matter where they are working from, including office users and remote users working from home or on the road.

With this product, SIP and H.323 are fully supported, along with other industry-standard protocols. Connection with PSTN and ISDN services is possible using Avaya’s media gateways, such as the Avaya G250. These media gateways work pretty much the same way as most vendors’, connecting to the Aura Communication Manager and providing inbound and outbound call routing to PSTN and ISDN services.

Critical environments can also have a second Communication Manager installed, providing high-availability and uninterruptible service in case the primary server is down. Extending this redundancy model further, in the event that both servers are down, users will automatically register to the media gateway — if available — and have access to basic telephony services until the servers are restored.

The Communication Manager is offered as a standalone hardware application server or a virtualized application. It runs on a Red Hat Enterprise Linux operating system, offering increased reliability, speed and smaller hardware requirements, as opposed to other non-Linux-based systems.

The Communication Manager can support up to 36,000 endpoints and 24,000 SIP trunks, making it a scalable solution for small to larger enterprises.
