RTPSend (RTP packet send tool)

RTPSend is a Windows-based application that enables precise control over RTP (Real-time Transport Protocol) packet transmission and reception. It supports audio codecs and video codecs, allowing users to send media from files, microphones, or generated signals, and receive streams for playback, analysis, or saving.

Designed to work seamlessly with SIP tools like SubstSIP, RTPSend provides a modular testing environment where SIP signaling and RTP media handling are clearly separated—ideal for developers and network engineers working on VoIP systems.
