What is the Difference Between VoIP and SIP?

The distinction between VoIP (Voice over IP) and SIP (Session Initiation Protocol) is essential to understanding how modern internet communication works. VoIP refers to the technology that allows telephony to take place over the internet rather than over traditional telephone networks. This technology converts your voice signals into digital data and sends it over the internet.

SIP, on the other hand, is a signaling protocol used specifically for starting, managing, and ending communication sessions over the Internet. This includes not only phone calls, but also video conferencing and messaging services. In simple terms, SIP can be understood as a communications director that handles the logistics and control of VoIP phone calls.

A key aspect of understanding this is that VoIP is the umbrella term for any type of voice transmission over the internet, while SIP is one of the possible methods that can be used within this broadband telephony. SIP defines how data transmission is initiated, performed and terminated and is therefore a set of rules that ensures structured and efficient communication management.

It is also important to note that SIP is not limited to VoIP. As it is a flexible protocol, it is used in various communication applications far beyond VoIP. The combination of VoIP and SIP provides a powerful platform for companies like Virtual-Call to offer comprehensive and flexible communication solutions to their customers.
