ABSTRACT:
Systems, methods and apparatus are disclosed to prioritize communications in Internet protocol Multimedia Subsystem (IMS) networks. An example method disclosed herein includes receiving a telephone number (TN), locating an ENUM database record for the TN specifying at least one non-IMS destination, receiving a plurality of current call parameters, and accessing a prioritization profile comprising a plurality of selection parameters. The example method further discloses evaluating at least one of the plurality of current call parameters based on the prioritization profile to select at least one of a plurality of non-SIP and non-TN URIs as a destination for the TN, and routing a communication session between the calling device and the selected URI. The plurality of non-SIP and non-TN URIs including at least one of an e-mail URI, an instant message URI, a fax URI, or a web URI.
