Caller-controlled routing to non-SIP/non-TEL URI destinations for an IMS-based ENUM query

摘要

A telephone number of the callee is received from a caller device. An Internet protocol Multimedia Subsystem (IMS)-based telephone number mapping (ENUM) query is constructed based on the telephone number of the callee. An ENUM database is queried based on the ENUM query. If a response to the ENUM query is absent a Session Initiation Protocol (SIP) Uniform Resource Indicator (URI) or a telephone (TEL) URI, the telephone number is resolved into one or more non-SIP/non-TEL URIs usable to communicate with the callee. The caller is enabled to use the caller device or other devices to select which of the one or more non-SIP/non-TEL URIs to use to communicate with the callee. For each caller-selected non-SIP/non-TEL URI, communication in a protocol associated with the URI is initiated between the caller and the callee using the caller device or other devices.
