The Complete Guide To


The award-winning experts at Amvia have compiled the complete business guide to VoIP. This guide covers how the VoIP phone systems work, how much they cost, what factors impact cost, the best business VoIP provider, which providers have the shortest and longest lead times, the most reliable networks, coverage, and much, much, more.



What is a VoIP service provider?

VoIP service providers enable your business to use voice over IP. They deliver your phones, your switch, and if you require, even your data link, for a monthly rental charge.

A VoIP provider will assess the needs of your business and help you understand the type of VoIP system you need. Part of the service is helping you spec the number of calls and bandwidth you'll require to make high-quality voice calls. They will check your internet access to make sure you are VoIP ready too. The provider will wrap all of their services up into a monthly fee. This fee usually covers phones, the VoIP system and an allocated number of call minutes per month.

What is a VoIP phone system?

A VoIP phone system allows your business to make and receive calls over the internet using voice over IP. Voice communication is converted into data packets transmitted over your data connection instead of the public switched telephone network (PSTN). 


A traditional phone system private branch exchange (PBX) uses the PSTN to initiate and terminate voice calls. Telecoms providers charge per minute for the use of this PSTN.

A VOIP phone system does not use the PSTN. The VoIP system sends voice calls over the data network. The use of the data network is why call costs between phones on the same VoIP system are free.

What are the advantages of VoIP?

A VoIP phone system is cheaper to run yet provides you with far more functionality. These advantages are expanded on below. The five main advantages of VoIP are:


It's easy to set up. It's simple to add and remove users. Creating hunt groups is quick. You wire a phone system separately, program changes using a consultant, and add hardware cards and ISDN lines to expand. Managing a phone system is simplified with VOIP.


Your staff are reachable wherever they are on landline, desktop, tablet or mobile. Connect your VOIP system with email, CRM and your support desk. You make your business more responsive by enabling your employees to remain responsive and available.


All of the latest technology is available, as standard: voicemail, conference calling, messenger, video chat and, auto-attendant. Advanced features such as Office 365 integration, file sharing, HD video, content suggestion, virtual meetings and whiteboards are available too.


VoIP providers can offer lower call costs than traditional phone system providers. The savings don't stop there, though. Buying a PBX used to be expensive; most providers charge a monthly rental. Management used to mean consultants, but now you can manage your system through a web portal.

Is VoIP cheaper than a landline?

There are three main elements of cost in a phone system: the calling hardware or software, the call costs, and the management costs.

VOIP phones are now the same price as PSTN phones. Calling is cheaper over VOIP as some calls are free, and call bundles are comparable.

Managing VoIP in an office is cheaper than a PBX phone system. If you have one or two phones, the management cost is comparable.

Overall, VoIP is marginally cheaper than a landline if you have five or more handsets. For 5-200 handsets, VOIP is much more affordable.

How much does VoIP cost?

A business VoIP system costs around £10/user/month. In addition, you will pay around £100/user for VOIP hardware. Therefore, a 15-user VOIP phone system will cost about £1500 to set up and around £150/month. The phone system will include 5000 minutes per user per month to UK landline, UK mobile, and 03 numbers.

The four main components which determine how much VoIP costs are explained below.


What type of handsets or desk phones do you require? The better and more feature-rich the handset, the higher the cost. Handsets range from £25-£500+


How many users will be using the system? More users cost more money. Budget for £10/user/month.


How much usage will there be? If you call internationally or premium-rate numbers, you may need a tailored call package.


What functionality do you need? A call centre solution will cost far more than a basic SME VoIP system.
