Resilient routing management approaches are provided based on primary/backup and failover/failback relationships in a clustered network environment, where each user and/or resource is assigned to a primary cluster and at least one backup cluster. A distributed handover mechanism enables global knowledge of primary/backup relationships between clusters and their assigned users or resources.

Resilient routing for session initiation protocol based communication systems

Call policy enforcement and routing is based on user location. A plurality of endpoints is provided for receiving and making calls. Each of the plurality of endpoints are assigned a default policy for controlling call authorization and providing call routing rules. A mapping of policies for a plurality of locations is stored. A location of a client associated with one of the plurality of endpoints is identified. A location-based policy is obtained from the stored mapping of policies of the plurality of locations based on the identified location of the client. The obtained location-based policy is applied instead of the default policy assigned to the client associated with one of the plurality of endpoints.

System, method and device for call policy enforcement and routing based on user location

A hybrid Unified Communications (UC) telephony deployment includes users of a tenant that are hosted between a UC cloud deployment and a UC on-premise deployment that offers PSTN connectivity for the users. An identity of a tenant and its' users are maintained consistently between the on-premise and cloud based UC deployment (e.g. telephone numbers, dialing preferences, voice mail . . . ). Each user of the tenant can register with the UC service from one or more locations (e.g. on-premise, off-premise . . . ) whether or not they are hosted by the on-premise deployment or the cloud based UC deployment. Functionality of the UC deployment may also be maintained at one or more locations within the hybrid UC deployment. For example, some services (e.g. voicemail, or other services) can be hosted in the cloud while the remaining services are hosted on-premise. Different Telco providers may be chosen by the tenant to provide PSTN services for one or more users of the tenant.

Hybrid unified communications deployment between cloud and on-premise

Service invocation information including call routing, reasons for redirections, and similar information are provided to party requesting a communication session and recipients of an enhanced communication system along the call routing path as the request is routed. Some of the information is filtered based on system and/or user defined rules, user permission levels, and comparable aspects.
