Question

Quizplus · Accepted Answer

Codec data (also called payload) is carried in the RTP portion of VoIP transport frames. RTP (Real-time Transport Protocol) is responsible for the delivery of voice and video data in real-time applications, and includes sequence numbers, timestamps, and the actual codec data. The IP header comes before RTP, but it does not carry codec data. UDP is the transport protocol used by RTP, while Ethernet and TCP are lower layer protocols that are not directly related to VoIP transport frames.
