Unveiling VoIP Protocols

VoIP protocols serve as a set of rules and specifications guiding software systems in connecting, establishing, and maintaining VoIP calls. SE Telecom sheds light on the crucial role these protocols play in orchestrating the coordination of user identification, codecs, channels, and media types for a flawless calling experience.

The Role of VoIP Protocols

Understand how VoIP protocols dictate the formatting and transmission of data, enabling the establishment and streaming of VoIP connections. SE Telecom explores the various functions of VoIP protocols, including transport, connection management, signaling, media description, media transmission, and security.

Most Common VoIP Protocols

Discover the powerhouse of VoIP protocols commonly implemented in today's platforms. SE Telecom highlights the importance of these protocols in ensuring the reliability and efficiency of VoIP calls.

Common VoIP Protocols:

  • Session Initiation Protocol (SIP): The backbone of VoIP, SIP establishes, maintains, and terminates connections, defining the format and order of messages between call participants.
  • Real-Time Transport Protocol (RTP): Responsible for delivering real-time audio and video media between endpoints during a VoIP call.
  • RTP Control Protocol (RTCP): Works alongside RTP, providing quality of service (QoS) and packet-delivery statistics for multimedia data.
  • Secure Real-Time Transport Protocol (SRTP): Ensures security by encrypting data, authenticating messages, and providing replay attack protection in collaboration with RTP.
  • Session Description Protocol (SDP): Collaborates with SIP, conveying basic information about the call, including session details, media types, and endpoint information.
  • Media Gateway Control Protocol (MGCP): Controls media gateways between the Internet and the public-switched telephone network (PSTN).
  • H.323: A system specification with multiple protocols that establish sessions for data-packet transmission over an IP network.

Supplementary or Less Popular Protocols

SE Telecom explores supplementary protocols that play specialized roles in VoIP calling, providing insights into their functions and use cases.

Supplementary Protocols:

  • XMPP and Jingle: Application-layer protocols integrated into VoIP and video calls for structured data transmission.
  • Inter-Asterisk Exchange (IAX): A SIP alternative providing VoIP telephony over the Asterisk private branch exchange (PBX) software.
  • H.248 (Megaco): Part of MGCP, enabling communication between media gateway controllers and gateways.
  • H.320: Facilitates narrow-band visual telephone systems for video-conferencing over the PSTN.
  • H.324: Provides standards for low-bitrate multimedia communication over traditional analog phone lines.
  • Skinny Client Control Protocol (SCCP): A proprietary protocol developed by Cisco for media conversion and signaling in Cisco VoIP phones.
