VoIP Cost: 2023 Phone Systems & Provider Price Comparison


VoIP stands for Voice over Internet Protocol and refers to the technology that allows routing of voice and multimedia data across the internet. You might already know VoIP phone systems as Voice over IP, Voice over Network (VoN), Voice over Broadband (VoB), or Internet Telephony. Whichever name you use, they are all the same.

But why would you want to use a phone system such as this?

VoIP allows users to make low-cost or even free cloud phone calls using their broadband connection to any phone in almost any country. Therefore, providing a communication method to help businesses save money and work more efficiently.

How Do VoIP Phones Work?

Most people know that computers and internet technology use digital data packets to communicate with each other. These same people also know that the human voice and, therefore, the telephone is analog data.

So how can we send analog data through the digital internet?

This is where VoIP comes in. The technology converts analog voice data into digital data.

Now, that’s clever.

Therefore, it’s now possible for you to speak into a VoIP phone and have the tech convert it to digital data. Then, send the data packets along a phone line or across the internet to be decoded at the other end.

How Much Does a VoIP Phone System Cost?

VoIP pricing depends on various up-front and running costs for hardware and software. If you’re looking for a VoIP system, you should inspect all the packages on offer to ensure they’re suitable for your business.

Firstly, VoIP phone systems prices vary depending on the number of users and, therefore, the size of your business. You also have to take into account the price of the equipment and the subscription to the software.

KSU-less systems

If you own a small business, you can use a KSU-less system providing decentralized phones. This system communicates without having a central switchboard or cabinet. Furthermore, many plans offer as few as two lines, costing as little as $30.

KTS systems

If yours is a mid-sized company with up to 40 users, you can choose a Key Telephone System (KTS). A KTS is a phone system that converts a public switched telephone network (PSTN), the single line that physically enters your building, into many internal business lines. This system also allows users to communicate with other phones connected to the internal network from their single desktop telephone. Usually, KTS phones are sophisticated enough to allow internal conference calls, access contact lists from a PC, and many more tasks that a basic telephone couldn’t do. These cost between $300 and $1000 per extension.

PBX systems

If your company is a large corporate with more than 40 users, a PBX system will probably be the best choice. A PBX, or Private Branch Exchange System, is a fully private network used within the company.

Users with PBX access communicate internally with other employees and the outside world. Furthermore, PBX phones can use different communication methods such as VoIP, ISDN, or analog. The typical cost of a PBX VoIP phone ranges from $1000 to $4000. Furthermore, services range from $9.99 to $100. This system is a lot more expensive than other phone systems, but the extra features available on each device will probably make it worthwhile.

VoIP Phone System Cost Factors

For the average person to understand how much VoIP systems cost to install, maintain and use, they need to consider a few factors:

Operational costs

These are the costs of managing and maintaining the VoIP network.

Typically, this includes:

  • Staff compensation for internal employees (usually your IT team) who oversee the VoIP system.
  • The cost of a managed service provider (MSP) to manage your VoIP system.
  • Additional running costs for power and cooling.

VoIP Hosting

If you want to host your own VoIP, you have to pay from $500 to $1000 per user. However, if you buy a hosted plan, it can cost as little as $20 per user.

VoIP Installation costs

Many VoIP providers charge customers for setting up a system and training their employees on using it. Although the costs vary between the providers, they can be $1000 to $5000 per IT employee. Usually, it’s these employees who then pass on the training to the end-user. However, many providers do this free of charge. Make sure you know whether your provider charges a fee or not.

VoIP costs per user

Most providers set their charges depending on the number of users. Therefore, consider how many employees you want connecting to the system.


You will need VoIP compatible handsets, headphones, softphones. These sell at different prices, so choose wisely.

Subscription costs

Usually, VoIP providers offer several subscription tiers with different features and cost varying prices. The cheaper VoIP rates tend to be the most basic and usually have the core features such as:

  • Unlimited VoIP calls
  • Limited landline calls.
  • Call holding and forwarding.
  • Voicemail.
  • Customer support during limited hours, usually daytime, and during a five-day working week.

In comparison, the more expensive plans offer the core features already mentioned plus:

  • CRM Integration.
  • Unlimited international and landline calls.
  • Voicemail-to-SMS message.
  • Voicemail to email.
  • Data analytics of each call.
  • Automatic call back.
  • More comprehensive customer support, such as 24/7.

Consider which of these features you need before signing on the dotted line. Otherwise, you might pay for unnecessary gimmicks.

Broadband connection

It makes sense to ensure you have a good broadband connection if you intend spending money on a VoIP communications system. The condition of your internet connection determines the clarity and reliability of your calls. Therefore, if you have poor internet in your building, consider an upgrade.

Length of agreement

Most VoIP providers offer contracts lasting 12 or 24 months. However, many VoIP providers can work out a personalized deal if you want one. Generally, a long contract will be cheaper than a short deal, and your monthly payments will be correspondingly less. However, if this is the first time you’ve used VoIP, it might be better to choose a short contract until you’ve found your feet and know which features you use the most.

VoIP System Features

We’ve already mentioned basic features such as voicemail, toll-free numbers, call waiting, and forwarding. But, there are many other features that many small businesses might not be aware of. There are, in fact, many other features that can help to run your business more efficiently.

Voicemail to email or SMS

This feature transcribes your voicemail message and sends it as an email or text to your chosen inbox. Usually, extracting information from a voicemail involves frantically scribbling contact and message details before the message times out. However, with this option, the software sends the transcript to you, formatted as an email or SMS text message to study in your own time.

Find me/follow me call routing

For mobile employees who might be in one of many different places, this feature is ideal. You program a list of numbers into the phone. Then, when you receive a call, the system tries each number in turn before sending the call to voicemail. Moreover, you can include mobile numbers as well, if your employee is away from the premises. Probably, one of the best functions of this feature is that if you want to work remotely from home, you can divert calls directly to your mobile, without the customer being aware.

Music on hold

Although most companies don’t like to put callers on-hold, sometimes it’s a necessity. If you’ve been put on-hold, you’ve probably had to put up with appalling “elevator music,” or maybe complete silence. The “music-on-hold” feature allows you to choose what your customers listen to while they wait for the call to be answered.

Call screening

Call screening is a valuable feature that users often overlook. When the phone rings, you can look at the display and see who is on the other end. Then, you can choose whether to answer the call there and then (if it’s a customer), divert it to your mobile (if it’s a private call) or refuse the call (if it’s a spam caller).

Training tools

Suppose you have a new employee who needs advice on how to deal with a customer. You can either wait until the call has ended. Or, better still, use the “barge and whisper” features to advise during the call.

Using “barge” allows you to listen in on a conversation without interrupting. You can either alert the employee to this or not, as you prefer. Then, use the “whisper” feature to advise your employee on the best way to handle the customer while they’re on the phone. But, without the customer being aware of it.

Conference calls

Most of your employees probably know about conferencing when many people interact on the same call. But, how many of them know the full range of tools they have available? Many conference call features allow you to set up a call monitor.

This allows you to:

  • Manage invitations.
  • Watch “hand raises.”
  • Mute conference phones.
  • And many more tools.

Although these tools can be handy when conferencing, they can also be challenging to use correctly and efficiently. So, ensure your employees know how to use this feature and train them accordingly.

Virtual receptionist

This feature is often part of many premium VoIP packages. But, few people use it properly. The tool allows customers to listen to a recorded message and use a menu to choose a particular extension. This electronic receptionist immediately makes your business seem professional and guarantees to impress your callers.

Do not disturb

Many people don’t realize that VoIP systems allow you to choose whether to prevent calls from interrupting you temporarily. This might be very useful if you’re in the middle of an important meeting, at a conference, or even more important, having lunch.  However, this isn’t the same as just turning off your phone. Instead, you can program the phone to divert the customer to your voicemail or send the caller to another phone.

Business vs. personal phone numbers

It’s always a good idea to keep business, and personal phone numbers separate. That way, you can divert business calls to voicemail outside working hours while still using your smartphone for personal calls.

How To Compare VoIP Plans & Costs

Suppose you’ve decided to take the plunge and choose a VoIP system for your business. You now have the problem of searching through the available information and choosing the best VoIP plans to suit your company. However, sometimes it’s tough to compare the various plans and costs because providers offer features that aren’t like-for-like, or this month’s special offer doesn’t include every feature you want for your company. Moreover, some providers give quotes based on the number of users, while others quote depending on the features you choose.

The biggest mistake that many customers make is to concentrate on the monthly package price. Just because one provider charges $10 per month while another charges $20 doesn’t mean that $10 is the cheapest. This is when you must look at what the price offers. For example, suppose that the $10 provider doesn’t offer voicemail transcription or call recording, and these are essential in your business. In that case, it makes sense to choose the provider who does offer those.

Therefore, when choosing your provider and the most suitable plan, look at all the features and the costs.

For example:

  • Single costs, such as setup and training. Also, buying hardware such as VoIP phones, headsets, or softphone apps.
  • Recurring costs, for example, monthly plan subscriptions. Also, take into account call costs (per minute) and costs per user.
  • Long-term costs, such as hardware maintenance and replacement. Also, as your company grows, you might consider a different plan that’s probably more expensive. You will also need additional lines and phone numbers.
  • What features will your company use and which aren’t needed?
  • Cost of upgrading your internet.
  • Cost of upgrading network equipment.

Questions To Ask Your VoIP Provider

Here is a list of questions to ask a potential VoIP supplier:

  • What are the startup and recurring costs? We’ve already covered these in this article. But, they are essential things to know.
  • Have you a money-back guarantee if the system doesn’t operate as promised?
  • We already have our company phone number. Can we port it to the new system, and how much does this cost?
  • I assume there’s a contract. But, are there cancellation fees, and how difficult is it to cancel?
  • Are there any hidden fees that I should know about?
  • Which features does my plan include? And, can I add extra features? How much are they?
  • Are we able to call internationally? Is this included in the package, or is it extra?
  • What customer support do you offer?
  • Does your system offer E911? If so, does this cost extra, or is it included?
  • Do you have a mobile app, or are we tied to the landline system?

Next Steps

Changing your company’s communication system over to VoIP is cost-effective. It makes your business run efficiently and gives a professional appearance to prospective customers. But, comparing the VoIP costs and available plans can be very difficult.
