Message Routing

The Oracle Communications Unified Session Manager performs routing in two ways depending on the routing precedence parameter in the sip registrar. Routing precedence can be set to either registrar (ENUM) or local policy. Routing precedence is set to registrar by default.

Registrar routing uses the configured SIP registrar/ENUM server for destination address queries. Local policy routing lets you configure routing decisions within the Oracle Communications Unified Session Manager’s local policy routing functionality.

If the Oracle Communications Unified Session Manager is performing any services for the call it performs those services prior to routing.

If, for any reason, the Oracle Communications Unified Session Manager is unable to proceed with routing a request, it replies to the station that sent the request with a 4xx response.
