What is the purpose of RTP in VoIP?

The Real-time Transport Protocol is a network protocol used to deliver streaming audio and video media over the internet, thereby enabling the Voice Over Internet Protocol (VoIP). RTP is generally used with a signaling protocol, such as SIP, which sets up connections across the network.
