A mobile device pass through for signaling messages procedure allows smart devices to participate in and control multimedia communications by providing the ability to control multimedia communications to the smart device by the mobile device. A mobile device and a smart device establish a channel of communications between the mobile device and a web browser executing on the smart device, e.g. when both are connected to the same Wi-Fi access point. When the web browser accesses a web application that utilizes signaling messages to control multimedia content, the web browser will send signaling message requests to the mobile device. The mobile device, in turn, generates and forwards the signaling message. Media content is delivered directly to the smart device without passing through the mobile device or the established channel of communications.
