RTP
Short definition
RTP (Real-time Transport Protocol) transports real-time media, including voice audio, across IP networks.
Meaning and how it works
After call setup, packets containing audio and timing information flow over RTP. The receiver uses the packet sequence and timestamps to support playback.
Business applications
- Business scenario:
During a typical IP phone conversation, SIP manages call setup while RTP carries the actual voice packets.
What to check before implementation
RTP does not encrypt its content by default. SRTP provides media protection. Packet loss, jitter and latency can affect call quality.
