摘要

A system and method of providing ringback video are disclosed. In one embodiment, the method includes receiving a connection request at an originating serving call session control function (S-CSCF) network element. The connection request indicates that a caller device has placed a call to a destination device associated with a ringback video service subscriber. The method also includes receiving a plurality of naming authority pointer (NAPTR) records at the originating S-CSCF network element from a telephone number mapping (ENUM) server. The NAPTR records include a plurality of ringback video uniform resource indicators (URIs) associated with the destination device. The method also includes modifying the connection request to include the plurality of ringback video URIs and sending the modified connection request to a terminating S-CSCF that communicates with the destination device.
