Abstract
System(s) and method(s) are provided for enabling routing and call completion among hybrid communication services. A client component receives a request to establish a call session, the request includes a service identifier tag that uniquely discloses a requested communication service. Client component validates the tag, and generates a query that is conveyed to a server, which supplies a set of Naming Authority Pointer (NAPTR) resource records (RRs) in response to query. The client component receives the set of NAPTR RRs; validates received Telephone Number Mapping (ENUM) embedded service and protocol identifiers associated with the NAPTR RRs; and associates the received tag with a matching NAPTR RR to route the call session and complete the call. Configurable logic that dictates association of the service identifier tag with a NAPTR RR also can enable routing and call completion when the tag is unavailable. A device that exploits service identifier tag is provided.
