What’s the Difference Between VoIP and SIP?

7th April 2021

If you’re new to the world of data voice communications through VoIP, you’ll be forgiven for feeling overwhelmed by some of the terminology! However, VoIP’s aim is to make your life easier not more difficult. Therefore, when considering your VoIP choices, it’s important to reach out to an expert who can help you make appropriate decisions. Today, we’re going to consider: what is the difference between VoIP and SIP?

VoIP and SIP are two very different terms used to describe much of the same technology. Crucially, the main distinctions are that SIP depends on VoIP – and that SIP trunking is a method of implementing VoIP into your workplace and your communications strategy. However, let’s take a close look at both terms in a bit more detail.voip vs sip

What is VoIP?

VoIP is Voice Over Internet Protocol. This means that you run voice communications over an internet connection, rather than through traditional telephone lines. Therefore, you are immediately benefitting from a more stable connection, a clearer line, and from more flexibility. Instead of depending on an old fashioned copper wire or perhaps outdated wiring setup in your office, you have one simple connection directly through your data provider.

VoIP works through data packets as opposed to through PSTN, and many companies are picking up the technology as the main standard for communicating with customers, clients and other businesses. Crucially, it is important to note that by the middle of the New 20s, even BT will be turning its back on PSTN, meaning a shift over to VoIP cannot come soon enough if you have not considered it already.

What is SIP?

To be able to run VoIP effectively, you are going to need to have some form of system in place so that you can run multiple applications through one unified operation. SIP, in its most basic definition, is a protocol. This protocol effectively allows you to make and manipulate calls through VoIP, and to use a variety of different services and programs.

For example, you may wish to use SIP trunking if you want to set up a video conferencing suite as well as a direct voice to voice connection. Ultimately, you’re likely to use SIP if you want to scale VoIP across your business. However, you don’t always need to use the SIP protocol if you just want to make use of VoIP in its raw form.

Using VoIP Without SIP

SIP isn’t the be-all and end-all when it comes to connecting via VoIP. In fact, it’s perfectly reasonable to have a simple VoIP solution in place if you are simply connecting a handful of different phones or devices. However, the need for a protocol such as SIP will likely come into play if you find that you want or need to take on more applications, or to increase the flexibility and versatility of your communications rig.

It’s worth remembering that SIP isn’t the only protocol you can use to harness VoIP. However, it tends to be the most widely available and the most popular. Crucially, despite the technical know-how required to scale SIP across a business, it is refreshingly easy to get up and running. That, likely, is what helps to make it so popular with engineers and users alike.

What Does This All Mean for My Business?

For your business, this discussion simply highlights how you can effectively enhance your communications for the better. VoIP may seem confusing at first, however, just as it is marvellously easy to use and adapt to, it shouldn’t take long for you to get to grips with. SIP, too, aims to make things much easier on you if you are just getting started with this comms standard.

If you are considering moving over to VoIP, doing so sooner rather than later is a fantastic idea. BT will be shutting down PSTN gradually, meaning now really is the time to take full advantage of the scalable technology that’s out there.
