Communication Server 1000
The Avaya Communication Server 1000, which enables a simple evolutionary path to the award-winning Avaya Aura ™ unified communications solution, is a full-featured, highly-scalable IP communications system that meets the needs of enterprises from small to large.
The Communication Server 1000 offers a comprehensive array of reliability and survivability mechanisms to ensure the integrity of your network, while enabling communications security through a full suite of security features and capabilities. The Communication Server 1000 supports a comprehensive array of business-critical telephony features and multimedia applications to any user that needs them — anywhere on the network.

Which Communication Server?
Communication Server 1000M — Well suited for Meridian 1 customers that are TDM-centric and want to maintain investment in their existing infrastructure while evolving to enjoy the benefits of IP applications and services.
Communication Server 1000E — Ideal for new customers that are IP-centric and want a flexible, reliable and secure IP Telephony solution with a broad portfolio of productivity-enhancing applications and services.
Resilient to ensure business continuity
Ensuring the integrity of your telephony infrastructure is critical to business success, which is why the Avaya Communication Server 1000 was specially designed with no single point of failure. The platform can also be deployed with an array of reliability and redundancy mechanism to ensure that even in adverse conditions, business continues as usual.
Campus redundancy — The Avaya Communication Server 1000's fault tolerance and operational resilience enable active and inactive call servers to be physically separated on different floors or in different buildings across a campus environment. With redundant call servers that can be separated from each other over a high-speed, reliable data link, if a disaster such as a fire or flood causes one call server to fail, the redundant call server will automatically take over.
Geographic redundancy — Since system failures are not always localized, enterprises must have broad-reaching failover mechanisms that provide continuity of service in the event of disasters or network failures. Implementing geographic redundancy enables networks to 'self-heal' in the event that the main call server is isolated from the rest of the network — allowing users to stay connected and business operations to continue.
Branch survivability — Connectivity between remote sites and their network can be impacted without warning. To minimize exposure in the event of these unforeseen circumstances, it's critical that offices be able to support their telephony infrastructure in isolation. A full suite of survivable branch office solutions are available to address the needs and requirements of branch offices from small to large.
Unified Communications Management — The Avaya Unified Communications Management (UCM) solution offers comprehensive management capabilities across voice, data and multimedia applications, utilizing a set of common services that serve as building blocks of a Service Oriented Architecture (SOA) for unifying management applications. Subscriber Manager is a fully-integrated component of UCM and can be launched as a network management application from the centralized console, securely and from anywhere in the network.
Voice quality management — Equipment reliability doesn't mean a thing if the network can't provide high-quality service. The Avaya Communication Server 1000 supports real-time monitoring and reporting of network conditions during calls — enabling quicker resolution to network problems and ensuring continued high-quality service. Proactive Voice Quality Management (PVQM) enables network managers to ensure the overall quality of their IP Telephony deployments. PVQM continuously and passively measures the user quality of experience (QoE) for IP Telephony communications, conducts system health checks for IP Telephony servers, and provides troubleshooting and resolution for any performance degradation or fault conditions to ensure the quality of VoIP communications.
Security — Increased user mobility combined with growing threats from legitimate and illegitimate users and devices represent a daunting challenge for companies who are trying to secure their networks. Fundamental to our architecture is a comprehensive layered defense approach that ensures the integrity and security of the network and its users. This offers numerous security capabilities that include firewall protection to secure against denial of service (DoS) attacks. The Avaya Communication Server 1000 supports a number of capabilities to ensure the security of its users, including the encryption of media and signaling traffic.
Location-based emergency services — The Avaya Communication Server 1000 employs intelligent emergency services globally (e.g., 911, 999, 112) that track the location of IP clients and direct calls to the appropriate emergency contact, even if that client is halfway around the world. Location-based emergency services are a core built-in capability of the Communication Server 1000, designed to ensure simple, effective and reliable service you can count on when you need it the most.
