Cisco Unified Communication Manager (Unified CM) 8.0(1) now includes a new Routing Rules interface, which enables an adjunct route server to make call-routing decisions. Once enabled, Cisco Unified CM issues a route request that contains the calling and called party information to the route server. The route server receives the request, applies appropriate business logic, and returns a route response that instructs Cisco Unified CM how the call should be routed, along with any additional call treatment that should be applied.

The route server can instruct Cisco Unified CM to allow, divert, or deny the call, modify calling and called party information, play announcements to callers, reset call history so voicemail and IVR servers can properly interpret calling/called party information, and log reason codes that indicate why calls were diverted or denied.
