Systems and methods for communicating media between a client and a media server. Responsive to a communication initiation received by a signaling controller from a client system, the signaling controller invites a media server by providing an invitation to the media server. The media server is bridged with the client system by controlling a media proxy service to establish a media proxy between the client system and the media server by using client media parameters of the first communication initiation and media server media parameters provided by the media server responsive to the invitation. Media is communicated between the external client system and the media server by using the established media proxy.
