Edit PJSIP Endpoint
Use this page to tune the PJSIP endpoint behavior behind a PJSIP extension. The settings here control media negotiation, NAT behavior, DTLS certificate handling, and transport-related media addressing. The screenshots use the Canistracci Oil demo PJSIP extension 101 Bella Stone.
