Abstract
Exemplary method and apparatuses for routing messaging traffic from a calling party in an Internet Protocol Multimedia Subsystem (IMS) network to a server in a destination network that serves a called party via the most direct route are provided. A telephone number mapping (ENUM)/Domain Name System (DNS) database, pre-provisioned to receive and respond to query messages based on an identifier of the called party and an application specific service type, e.g., short message service (SMS) or instant messaging (IM), may be accessed by a node in the calling party's IMS network to determine an address of the server in the destination network. Messaging traffic may be routed to the destination network or server based on content type or destination digits when ENUM/DNS database based routing mechanisms fail. Furthermore, routing of messaging traffic originating in an enterprise network and routing through the public switched telephone network (PSTN) is enabled.
