摘要：
Methods of routing a non-IP multimedia subsystem (IMS) message from a first user terminal that has telecommunications service provided by a first carrier to a second user terminal that has telecommunications service provided by a second carrier are provided. Pursuant to these methods, a first telephone number mapping (ENUM) database is queried to identify an address of a second ENUM database that is operated by the second carrier. The identified address is used to query the second ENUM database. Routing information for the non-IMS message is received from the second ENUM database in response to the query to the second ENUM database. The non-IMS message may then be routed to the second user terminal based on the routing information received from the second ENUM database. Related systems and computer program products are also provided.
