Abstract: In one embodiment, an endpoint in a network sends a Session Initiation Protocol (SIP) registration request to a device. The device generates a first key using information included in the SIP registration request. The device also writes the first key to a storage location accessible by a Traversal Using Relays around Network address translators (TURN) server. The endpoint generates a second key based on the information included in the SIP registration request. The endpoint sends an allocate request to the TURN server that includes the second key. The TURN server authenticates the endpoint based in part by comparing the second key to the first key. The endpoint receives an allocate response from the TURN server, after the TURN server authenticates the endpoint.
