Enhancing media characteristics during Web Real-Time Communications (WebRTC) interactive sessions by using Session Initiation Protocol (SIP) endpoints, and related methods, systems, and computer-readable media are disclosed herein. In one embodiment, a method comprises intercepting, by a media redirection agent of a WebRTC client executing on a computing device, a WebRTC initiation token. The method further comprises generating a SIP endpoint WebRTC token based on the WebRTC initiation token, and sending the SIP endpoint WebRTC token to a remote endpoint. The method also comprises establishing a WebRTC interactive session between the remote endpoint and a SIP endpoint based on the SIP endpoint WebRTC token. By leveraging the audio and/or video functionality of the SIP endpoint, the media characteristics of the WebRTC interactive session may be enhanced, resulting in an enhanced user experience.
