Abstract
According to one embodiment of the present invention, a system for providing call signaling services to client devices transmits a start channel message on a service topic from a first client device to a service instance. The system publishes from the service instance to the client devices a channel message including a channel topic. The service instance subscribes to the service topic and an associated channel topic. Each client device subscribes to a corresponding client topic. The system transfers signaling information between the client devices and the service instance by publishing signaling information to a channel topic and client topics to establish a communication Channel between the client devices. The system communicates between the client devices by publishing information over the communication channel. Embodiments of the present invention further include a method and computer program product for providing call signaling services in substantially the same manners described above.
