When creating an external trunk, which of the following protocol(s) can be selected? (Choose three.)
When creating an external trunk, the protocols that can typically be selected are TCP (Transmission Control Protocol), TLS (Transport Layer Security), and SIP (Session Initiation Protocol). RTP (Real-time Transport Protocol) is generally used to carry media streams and not for trunking, and UDP (User Datagram Protocol) is often used for media transport but not necessarily for creating an external trunk setup.
