Frequently Asked Questions

What is a VoIP phone system?

VoIP is an abbreviation for ‘Voice over Internet Protocol.’ Traditional phones use the Public Switched Telephone Network (PSTN), which routes calls across copper cables linked by telephone exchanges.

VoIP technology, on the other hand, turns your voice into a digital signal that allows you to make internet calls. This is how a VoIP phone system lets you make and receive calls over an IP telephony network without restriction.

How does a VoIP phone work, and what is it?

A VoIP phone looks and works just like a regular desk phone and usually does the same things. The main difference is how your phone calls travel through the network. With VoIP, this is done through an Internet connection instead of the traditional Public Switched Telephone Network (PSTN). Most VoIP phones will be able to do more things than their traditional counterparts.

Can you use my old phones with a new VoIP system?

You would need a special adapter to connect your regular phone to a VoIP network. We don’t recommend this because we find purpose-made VoIP phones are much more useful than older ones. They are designed specifically to make it easy for you to use VoIP phone functionality.

Can you supply cordless VoIP phones?

Yes, we can provide many brands of cordless phones that work with VoIP services, like those made by Yealink and Samsung.

Can I keep my old business phone number?

Switching to VoIP phones does not mean you have to give up your current business phone number. We will take care of the coordination between your current and new phone service providers.

How would a VoIP phone system in the cloud work with my cell phone?

You can use your cell phone in a number of ways with a VoIP system. You can set your cell phone to ring when your office phone does, which is helpful if you’re not at your desk or in the office.

Most systems let you flip calls from one phone to another. So, if you answer the office phone when you need to leave the building, you can switch the call to your cell phone without any trouble.

With a VoIP mobile app for Android and iOS devices, you can turn your smart phone into an extension of your VoIP phone system, letting you set up call routing, transfer calls, and do much more.

How do you make a VoIP phone call?

It’s just as easy to make a VoIP call as it is to use a regular phone line. Just dial a number as you normally would on your VoIP device, and the call will go through your internet connection.

What is the difference between VoIP phones and landlines for business?

Cloud-based VoIP phone systems can do more than your old phone system can. You can use call forwarding, call transfer, three-way calling, and automatic call routing very easily as well as recording calls, embedding requirements that meet your compliance needs, and integrating with other systems including CRM, call centre or ticketing systems.

With traditional landlines, you have to buy and take care of expensive equipment. With a VoIP phone system, you don’t have to do that, so you can keep your budget in check.

It also makes sure that you’re ready for the future, since all businesses will have to switch to digital phone lines by 2025.

How reliable are VoIP phone systems that run in the cloud?

Most VoIP phone systems will work 99.99 percent of the time if you have good internet. Plus, you have the support of our UK-based helpdesk 24 hours a day if anything does go wrong.

How secure are VoIP phone calls?

The data centres that reputable VoIP providers use to offer digital voice services go through regular audits. They use the latest firewalls and intrusion detection systems, and all the data they handle is encrypted.

VoIP technology includes several features to keep your people, systems and data safe, including Secure Voice and SIP over TCP.

What are some disadvantages of using a VoIP phone system?

There aren’t many bad things about VoIP phone systems, but some businesses may have trouble with call quality and reliability. This is usually caused by a poor internet connection or less than optimal network within your business premises.

We make sure our customers will get great performance by advising them if upgrades are needed. We also only provide quotes from VoIP companies that have been around for a while and have a history of being reliable.

How much does an average VoIP phone system cost in the UK?

How much you’ll pay depends on several factors. It depends on which system is best for your business and how it’s configured.

The best thing is to ask for our ‘Total Cost of Ownership’ analysis of your current system, which will be formatted in our standard layout that matches all the bids and price quotes we’ll get from VoIP phone system providers for your during procurement. This makes it easy to compare VoIP providers and pricing structures.

What is SIP trunking?

The acronym “SIP” stands for “session initiation protocol,” and SIP trunking is the technology that enables phones to talk to each other over the internet instead of physical phone lines.

As SIP initiates the procedure that enables voice and data to be sent between devices, it opens up the channel for VoIP calls to begin.
