An originating user equipment may generate a request to utilize a service that links over-the-top content with a voice call, and may provide the request to an entitlement server of a core network associated with the originating user equipment. The originating user equipment may receive, from the entitlement server, information verifying entitlement of the originating user equipment for the service. The information may include a tag identifying the service. The originating user equipment may provide an invite message, with the tag, to a terminating user equipment and may establish the voice call with the terminating user equipment based on providing the invite message and via an Internet protocol multimedia subsystem (IMS) network and the core network. The originating user equipment may establish, concurrently with the voice call, a connection for the over-the-top content with the terminating user equipment via a data network and the core network.
