Avaya Communication Manager is renamed as Avaya Aura Communication Manager from Release 5.2.

This release focuses on reducing total cost of ownership, realized in several areas of the network architecture, designed particularly for enterprises considering a Flatten/Consolidate/Extend project to reduce costs and simplify management. Release 5.2 also brings improvements to the SIP-based solution by increasing trunk and endpoint capacities and adding support for Session Manager.

  • Processor Ethernet for duplex servers: Extension of Processor Ethernet capability for S8720 and S8730 duplicated critical reliability servers. Allows H.248 media gateways, H.323 endpoints and SIP endpoints to connect directly to the server's Ethernet interface. Eliminates need for an expensive G650 gateway and allows a cost-effective H.248 gateway to be used instead, providing up to 50% hardware cost savings.
  • S8510 Embedded Voice Messaging: Integrated voice messaging (previously supported on S8300 and S8400) is now available on the S85x0 media server providing a cost-effective messaging solution for medium-size customers.
  • S8400 Enterprise Survivable Server: It is now possible to configure S8400 as an Enterprise Survivable Server (ESS) to provide enterprise-wide disaster recovery.
  • Increased endpoint and trunk capacity: On S87x0-series servers IP (H.323) endpoint capacity is increased from 12,000 to 18,000. SIP capacities are increased from 12,000 to 18,000 endpoints and from 5,000 to 7,000 trunks.
  • G430 Gateway: The G430 is a new H.248 media gateway intended for branches and sites with 2 to 150 users. The G430 has the same features as G250, G350 and G450 gateways, including SLS (standard local survivability) integrated in the gateway.
  • Survivable SIP Gateways: Solution support for small, low-cost third-party and customer-installed SIP gateways and Avaya 9600 series phones enables remote branches to stay connected during WAN outages.
  • New telephony features: supports new telephony user features.
