Session Manager Controls Calls
The Avaya Aura Session Manager is the core of Avaya’s SIP-based architecture, unifying all Avaya UC services. Aura Session Manager integrates with Avaya’s Aura Communication Manager, media gateways, messaging services, session border controller, conferencing, contact center and more, creating a centralized infrastructure that helps lower the total cost of ownership and administration costs.
Avaya’s Aura Session Manager has the unique ability to allow enterprise-wide dial plans across multiple vendor PBX environments. It can create system wide network routing rules to route calls in a cost-efficient manner using least-cost routing methods, alternative routing, time-of-day routing, toll avoidance and more.
Session Manager is truly an enterprise product, as it can support up to 250,000 SIP users, 350,000 SIP devices, 300,000 dial patterns, 1,000 SIP domains and many more. It supports connectivity to Cisco, Siemens, Alcatel-Lucent and other third-party PBXs, making it flexible and easy to integrate with existing infrastructure.
With a tolerance of up to 1,000-millisecond (ms) round-trip delay — from the source to the destination and back — it is suitable for almost any network environment, even satellite connections, which typically fluctuate between 600 to 900 ms round-trip delay.
