2. VoIP / SIP / RTP Ports

Voice over IP systems depend on a complex mix of signaling and media protocols. This dataset covers SIP, SIP-TLS, STUN, TURN, RTP, and RTCP, along with dynamic media port ranges used by modern UC platforms. It’s designed for teams deploying VoIP systems, diagnosing call failures, optimizing QoS, or securing VoIP traffic against toll fraud and unauthorized use.

Clear understanding of these ports helps prevent dropped calls, one-way audio, NAT traversal problems, and exposure of VoIP infrastructure to the Internet.
