Avaya Session Manager (SM) Redundancy

To support redundancy in Avaya SM deployments, the Oracle® Enterprise Session Border Controller can use the mechanisms for maintaining multiple connections defined in RFC 5626. In an Avaya SM deployment, this scenario is referred to as Dual Registration.

RFC 5626 specifies a method of maintaining connections between UAs and proxies, and outlines a general means for UAs to establish connection redundancy. The Oracle® Enterprise Session Border Controller can use RFC 5626 specifically for redundancy in Avaya SM Dual Registration deployments. Such a deployment allows the network to continue to provide service by way of a redundant Avaya SM, when the primary Avaya SM stops responding.

Oracle® Enterprise Session Border Controller configuration requires adding the rfc 5626 SPL option. In addition to adding the SPL option, the Oracle® Enterprise Session Border Controller configuration design separates Avaya SMs and UA traffic by way of using realms.
