A request to establish an encrypted media stream is received, by an edge server, for a Web Real-Time Communication (WebRTC) communication session between a first browser, and a second browser or gateway. The edge server is a boundary device between a first network and a second network. The edge server retrieves a tenant identifier for the encrypted media stream. The tenant identifier can identify a specific company or enterprise. In response to receiving the tenant identifier for the encrypted media stream for the WebRTC communication session, a list of one or more Quality-of-Service (QoS) parameters associated with the tenant is retrieved. For example, the list of QoS parameters may be based on a Service Level Agreement (SLA). The edge server dynamically sends a message to configure the second network to support the list of one or more QoS parameters associated with the tenant.
