What is SIP?
The meaning of the SIP acronym is Session Initiation Protocol. SIP is a signaling protocol that allows the Voice Over Internet Protocol (VoIP) by sending a command to the softphone or VoIP phone with the SIP account credentials allowing the “initiation” of the VoIP phone call “session” on the phone device.
SIP is the protocol used to deploy a VoIP call on a particular device. It is used to connect local telephone systems like virtual PBX’s, softphones and mobile apps to the public telephone network to connect users without a traditional telephone line.
Example #1 of the SIP protocol components explained: sip:bob@114.5.41.123, in this string “sip” is the protocol we are requesting to open the device that will make the call, “bob” is the SIP account username and “114.5.41.123” is the IP of the SIP server or host of the VoIP provider.
Example #2 This example is more interactive, if you click here sip:15555555555 a message will pop up confirming that the softphone installed on this device will initiate the call to the phone number 15555555555.
Other VoIP deployment protocols are Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), and Session Description Protocol (SDP).
SIP vs VoIP
SIP is a protocol used to deploy applications to send voice messages. VoIP is a technology used for sending and receiving voice packages over the internet.
What is a SIP trunk and how does it works?
A SIP trunk is the VoIP version of a classic wired telephone line. SIP trunking is a method of sending voice messages and other means of communications through the internet by interconnecting the server IP of the caller and the server IP of the SIP Trunking provider, with this interconnection SIP trunking allows the calls to initiate.
