Disclosed herein are methods and systems for link-based enforcement of routing of communication sessions via authorized media relays. In an embodiment, a media relay receives encrypted first payloads from a first endpoint and encrypted second payloads from a second endpoint as part of a session. The encrypted first payloads require a first key for decryption and the encrypted second payloads requite a second key for decryption. The media relay is preconfigured prior to the session with secrets useable for identifying the first and second keys. The media relay decrypts the first payloads using the first key and decrypts the second payloads using the second key, and transmits the first payloads to the second endpoint and the second payloads to the first endpoint as part of the session.
