Technology is a constant partner in our day to day living. Although it is present all the time, however, it is hard to believe that many people really do not know how technology really works and which are the mechanisms associated with it. The truth is that its terminology is full of acronyms and technical terms that could be overwhelming for those who are not experts.

Only in the telecommunications industry alone is there enough material to write several manuals with all the terminology associated with this industry. Although knowing all the technical terms could be overpowering for some users, especially beginners, it is important to have a general idea of those concepts and know which are the most relevant and how they work in order to avoid misunderstandings. Most of them seem to be complicated, but the majority are simple to understand.

One of the best examples that reflects this reality is the confusion that exists between the terms VoIP and SIP. Some people think that they are the same thing, while others think that they are two different services and try to mistakenly compare them. Let’s see what they are and how are they related.

What is VoIP?

VoIP stands for Voice over Internet Protocol: it is a technology that allows users to make calls through an internet connection. This system has become very popular and used between netizens due to its low cost, wide range of features, versatility and flexibility. Everyone is familiar with this technology, maybe not by its name but certainly by the use of it. For example, with a strong internet connection, some VoIP services allow users to call anyone, anywhere in the world, without paying the service provider for the call. Sounds familiar, just like Skype, right?

This technology is predicted to completely replace traditional phone lines in the coming years. VoIP works by converting analog audio signals into digital data packets which are transmitted over the internet to their destination.

What is SIP?

Session Initiation Protocol, commonly known as SIP, is a protocol that is used to initiate, maintain and terminate multimedia communication sessions. SIP can be used to transmit information between two endpoints or many.

Before getting deeper into SIP, it is important to understand that a protocol is a set of rules or procedures for transmitting data between devices. Basically, it is like a universal rule book. For devices to be able to exchange information, there must be a prior agreement of how the information will be structured and which one will send and receive the data. Protocols with the same language make devices to be able to communicate, whereby, they are universal.

In 1996, SIP was developed as a way to improve the form in which IP-based calls were handled, just a year after the first time ever VoIP system was released to the market and it started to support phone calls as a new technology. The growth of SIP has been linked to that of IP communications since they both emerged.


SIP works as a bi-directional communication system. Many different types of data travel across a single network at different times. This protocol is in charge of ensuring that the data does not get lost, by providing the structure of how that data gets from point A to B. That is to say, one device sends a request and the other device receives it, and then responds. Users benefit from SIP as it allows them to connect across different networks quickly and reliably.

VoIP vs SIP

VoIP and SIP cannot be directly compared because they are two completely different things. While VoIP is an internet-based phone service, SIP is the protocol that is used in different types of VoIP deployments. In other words, SIP is one of the protocols that enables VoIP communications, so they work together. SIP makes it possible to enjoy other forms of VoIP communication beyond only voice calls. It supports instant messaging, videoconferencing and other multimedia features, so it works as a complement.
