VoIP phones are becoming increasingly common in use, especially in businesses. But what exactly are they?

VoIP stands for Voice over Internet Protocol, which means that it allows you to make free or very low cost, telephone calls over the internet. You can call any telephone in the world and any telephone can call you, regardless of what equipment or network the person you are calling uses.

With the emergence of the internet and its incredible boom in popularity, particularly in the late 1990s, more companies began to explore VoIP as a serious alternative to regular landline calls.

How does it work?

With VoIP, analog voice calls are converted into packets of data. The packets travel like any other type of data, such as e-mail, over the internet and/or any private Internet Protocol (IP) network.

You are able to call landline or mobile phones, as well as being able to call computer-to-computer, with both parties speaking into a computer microphone and listening through computer speakers or headsets. It’s worth noting that you can make or receive calls using landline telephones; all you need is an analog telephone adapter connected to your network.

VoIP calls can be totally free and that all sorts of new services become possible with them, like video calls.

How VoIP Works for Your Business

You’ll save money by having one network to manage instead of two. You can easily add, move, or change phone extensions and locations, which saves money and gives you more flexibility. However, calls made in this manner are generally much cheaper than making landline-landline or mobile-mobile phone calls. This especially applies to the international rates offered by companies such as Skype.

If a business operates over several sites, VoIP can make good financial sense as it avoids expensive internal calls – and even if a business operates at just one site, using VoIP can be beneficial when contacting customers.

VoIP services take a variety of forms; from PC to PC (like Skype for Business), PC to telephone network, telephone network to telephone network and IP phone to telephone network.
