Join Greg Sowell for an in-depth discussion in this video Transfer VOIP: SIP, MGCP, RTP, and H.323, part of Foundations of Networking: Protocols and CLI Tools.
- [Voiceover] Voice over Internet Protocol…is a method to carry voice traffic digitally over a network.…Initial providers release services…that emulate the traditional phone systems,…changing out analog lines for digital.…More recently, call services like Skype…have started offering new alternatives.…Session Initiation Protocol…is a signaling and control protocol for communications.…It is most commonly used…for voice and video delivery over an IP network…but can also carry instant messaging.…
SIP is primarily responsible for establishing…and terminating these communications…but not carrying actual voice traffic.…SIP uses TCP and UDP port 5060 for plain text traffic…and uses TCP and UDP port 5061 for TLS encrypted traffic.…SIP packets employ a structure very similar to HTTP,…including header fields and encoding rules.…SIP resources are marked with a Uniform Resource Identifier,…much like web resources.…The URI scheme employed is usually in the form…of sip:username:password@host:port.…
SIP will often be employed on a digital office phone,…
