The 10 Best VoIP Business Phone Systems for Under $25/Month

Samir Sampat

A mere three or four decades ago, we had but one way to make a call: pick up the phone. Today, technology has evolved so much so that the regular old telephone is becoming one of the least common ways to make or take a call. 

Think about it—the smartphones we carry in our pockets offer more than just the phone (which, by the way, is an “app” on the device already). You can video call, call via Facebook messenger, use FaceTime, and so much more. These services are plentiful and although we may have never dreamed them up before, they’re all possible thanks to one simple technology: VoIP. 

Voice over Internet Protocol, or VoIP, uses data lines to turn communication into “packets” of information that are sent over the network to the other end of the connection. Some IP networks are directly connected to a service provider while others go through the Internet service provider. What matters is that there is a certain Quality of Service (QoS) required to ensure the best quality of communications for your audience. 

There are several benefits to VoIP and as it continues to become a more common method of communication. SMBs and other businesses are finding monthly plans that are a lot more affordable than they might anticipate. In this guide specifically, we’ll take a look at 10 of the best VoIP systems that will cost you less than $25 per month. 

As a bonus, we’ll also take a minute to look at the benefits of Voice over Internet Protocol plans, both in general and as compared to traditional phone services. By the time you’re done reading, you’ll have a better idea of the options and a better idea of what’s in it for your business. (spoiler alert: plenty!)


The perks of using VoIP


There is a lot that your business can gain from upgrading to a VoIP service from traditional phone networks. The benefits are seemingly endless and a simple Internet search will point out the best reasons to switch now. When considering VoIP for your business, look at benefits like:

  • Service mobility that allows you to take calls, chats, and other communications anywhere. 
  • Low cost-per-call so that you spend less on communications and can make more calls with a smaller budget. 
  • Versatile features, including customizable auto attendants, intelligent call routing, and AI galore that will help streamline productivity. 
  • Cloud-based storage for unlimited data and plenty of backup support.
  • Video, voice, text, and other communication methods in an omnichannel platform that makes it easy for your audience to stay in contact. 
  • Scalable, reliable plans that suit the needs of any growing SMB. 
  • Impressive reliability, with most VoIP servers reporting more than 99.99% uptime so that you never have to worry about dropping a call. 

These are just a few of the biggest perks to keep in mind. Now, let’s look at how you can get all that for less than $25 per month with the best VoIP systems below.

Phone.com offers basic access for less than $15 per month, but minutes are limited and you won’t have access to as many features as you might find with other platforms on this list. It also doesn’t offer compatibility with IP desk phones and it may lack customization in some areas. 

Check out key features like:

  • Price: $12.99 per user, per month to start
  • Vanity numbers available
  • Up to 300 participants on audio
  • Ability to mix and match plans

Dialpad is another affordable solution for VoIP when you want custom mobility solutions or integrations. It offers AI-based voice intelligence that collects actionable content from calls, along with syncing with platforms like G Suite and Outlook. The customer service functions are impressive, but the limited reporting may leave something to be desired for certain users. 

You will have to pay for certain add-ons and upgrades, but if you just need a basic call center tool that gets the job done, Dialpad will get you started with VoIP quite easily. Video conferencing for groups will cost extra, but the affordable pricing is worth it.

While this one barely skirts under the budget for $25 or less plans, it’s worth mentioning because it’s worth the money regardless. 

RingCentral includes AI and intelligent call routing, along with a full-service PBX that gives you the VoIP that you need. This platform is best for those who have a little more to invest because the higher plans offer better packages for the money, but it’s still great for anyone who needs a dedicated VoIP platform.
