7 Best Business VoIP Phone Systems that Will Work with Your Desk Phone

Sean Lund-Brown

While many people are looking for a modern VoIP provider that can turn their smartphone or computer into a dedicated phone system, there are still several companies and individuals that like the idea of having a handset that they can use to make and take calls, transfer to others, and so forth. 

Technology has come a long way, but there are some parts of business that will remain even as they evolve. For some businesses, the desk phone is one of those items. Having a dedicated phone system is a big investment and when you’ve already spent a fortune on the hardware, the last thing that you want to hear is, “Hey, you don’t need those anymore!”

Not only that, but some things are just better done the old-fashioned way. Computers and smartphones are great, but the routing capabilities and tech features of the modern desk phone are rather impressive, too. If you’ve decided that your VoIP upgrade is going to be for the desk phone, we’ve got the providers that should be on your list. 

As you would with anything, you’ll need to compare the features that are offered based on your budget, as well as the plans offered. Budget-minded shoppers will also love that some of these providers offer discounts on their service when you pay annually instead of monthly. It’s all about finding what works for you. In the list below, we’ll look at seven of the best companies to consider when you want to keep the desk phones. 

When you’re choosing a VoIP provider, there are a lot of different features that you’ll find. Make sure that you focus primarily on things like:

  • Customer service and reputation
  • Unlimited calling and texting (are these included or extra?)
  • Included features for the price
  • Upgrade and scalability features
  • Customization options 

There are a lot of different elements you could consider, but these should be first on your list. After all, it doesn’t matter how affordable a service is if it is of poor quality or doesn’t meet your needs. Before we get ahead of ourselves, though, let’s stop and talk a little more about what VoIP is, why it is becoming the preferred method of business communication, and more. 


The case for VoIP


VoIP stands for Voice over Internet Protocol. It’s the process of sending audio in data packets over data lines instead of transmitting calls via traditional telephone lines. It might sound complicated, but essentially, you’re calling over the Internet instead of the phone. That provides a number of different benefits, starting with a much lower cost-per-call, giving more businesses the chance to upgrade to real business phone solutions without breaking the bank. 

Other perks of VoIP that you need to consider include:

  • More call flexibility—take calls from anywhere, on any device, thanks to VoIP providers with mobile apps and other tools to keep you connected on the go. These providers are all about improving your communications and helping you make things better, and they do this with the services that they offer. 
  • More comprehensive calling plans and solutions. You no longer have to pick and choose between overpriced plans that have features you’ll never even use. Most VoIP providers will allow you to customize the plans that you choose with the features that you need so that you’re never paying for anything that you don’t need. 
  • Enhanced security features and more call tracking support. You’ll be able to use information and intelligence gathered from your calls in a whole new way. Calls are made across secure lines and give people the chance to connect with you in several ways. 
  • Better options for solopreneurs and SMBs. While major VoIP providers and traditional phone companies focus a lot on enterprise organizations, there are several solutions geared toward the small businesses out there today. That includes several in the list below, and many that are free to start or for basic access, too. 
  • A chance to improve your phone system without a huge hardware investment. When you choose VoIP providers that are compatible with the desk phones that you have, you’ll save a small fortune and be able to get a lot more for your money. You can even choose a VoIP system that has its own desk phones, and you’ll still find that they’re much more affordable than traditional phone systems. 
  • VoIP also supports flexible communications and multitasking, helping you improve your business operations in several different ways. You’ll have flexible solutions to take care of communications in a whole new way and you’ll be able to deliver better services to your audience. Plus, you’ll do it all for a fraction of the cost, as we mentioned above. 

These are just a few perks to consider when you’re looking to upgrade to VoIP. Once you see just how much you can get for your money, you’ll be quick to make the transition. And when you’re ready, the brands in the list below will be there to help.
