Which transport layer protocol is recommended for carrying voice?

UDP/IP
Due to the time-sensitive nature of voice traffic, UDP/IP was the logical choice to carry voice. More information was needed on a packet-by-packet basis than UDP offered, however. So, for real-time or delay-sensitive traffic, the Internet Engineering Task Force (IETF) adopted RTP.

Which transport layer protocol would be used for VoIP applications?

For VoIP, the transport layer uses UDP, user datagram protocol. (UDP is used also for real-time videoconferencing networks.)

Is voice traffic UDP or TCP?

Because a real-time communications service such as Voice over IP does not require a completely reliable transport protocol, UDP is the ideal protocol for voice calls in VoIP.

Which transport protocol carries voice and video?

Real-time Transport Protocol (RTP)
Real-time Transport Protocol (RTP) – RTP carries the actual media streams, whether voice, video or both.

Which protocols are used to carry voice traffic?

Voice over Internet protocol (VoIP) carries voice via data networks, a fundamental change from analog POTS, or plain old telephone service, which remains in use after over 100 years. VoIP brings the advantages of packet-switched networks, such as lower cost and resiliency, to the telephone.

What are the protocols of VoIP?

VoIP protocols include:

  • Session Initiation Protocol (SIP), connection management protocol developed by the IETF.
  • H.
  • Media Gateway Control Protocol (MGCP), connection management for media gateways.
  • H.
  • Real-time Transport Protocol (RTP), transport protocol for real-time audio and video data.

What are the voice protocols?

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.

Which applications use UDP at the transport layer?

Following implementations uses UDP as a transport layer protocol:

  • NTP (Network Time Protocol)
  • DNS (Domain Name Service)
  • BOOTP, DHCP.
  • NNP (Network News Protocol)
  • Quote of the day protocol.
  • TFTP, RTSP, RIP.
