1. An apparatus, comprising: an information collection component of an interoperability server that receives, from an endpoint, an advertisement of information associated with the endpoint; an analysis component of the interoperability server that dynamically determines if the endpoint should be connected to a virtual talk group (VTG) based in part on an analysis of at least one of the advertisement or information determined based on the adherence of the endpoint with a predefined floor control mechanism; and a dynamic proxy component of the interoperability server that makes a determination to dynamically insert a proxy that adheres to the predefined floor control mechanism when the determination by the analysis component concludes that the endpoint is not in adherence with capabilities of the predefined floor control mechanism, the capabilities comprising quality of service, rules of transmission, and trusted endpoint identity; when the endpoint is conforming with the capabilities, connecting the endpoint directly to the VTG without the proxy, and connects the endpoint to the VTG in response to the determination.
