Most Commonly Asked Questions About Business VoIP

Looking for an affordable yet reliable business VoIP provider? Look no further. We have you covered. In addition to our comprehensive reviews, we've compiled answers to some of the most commonly asked questions to help you get started.


What is VoIP?

VoIP, Voice Over Internet Protocol, enables you to make and receive calls through your internet connection as opposed to a traditional phone carrier. For many businesses this is a cost-effective and highly efficient solution. However some businesses choose to use VoIP to supplement their phone service as some VoIP providers don’t offer common phone services like emergency calls and phone directory listings.


What is an IP phone?

An IP phone, also known as a VoIP phone, is a phone which relies on internet technology to make and receive calls. With VoIP phones, voice calls are converted into data and transferred in a similar way to email. The useful thing about these phones is that they can be used to call landlines, mobile phones and can even be used for computer-to-computer calls. Such a phone can improve the daily running of your business and save you money in the long run.


How does the voice clarity of VoIP service compare with traditional phone carriers?

Voice clarity varies from provider to provider. This is also dependent on the quality of internet connection. The faster and more reliable your internet connection, the better your VoIP experience will be. But the good news is that many businesses around the world make regular use of a VoIP service and enjoy a quality, hassle-free experience.


Does your computer need to be turned on to use VoIP?

One of the best things about VoIP is that your computer doesn’t need to be on to use it. Of course, your internet connection does need to be working. All you need to do is plug your VoIP phone into your internet connection and you’re good to go.
