The 10 Best VoIP Phone Providers for Law Firms


Nothing is more important for law firms than communicating with clients and leads. You’ll need to answer questions, schedule consultations, communicate progress on cases, and more. Of course, your law firm also has many other communications needs, ranging from collaborating with peers to contacting expert witnesses and everything in between.  

Traditional landlines can help you accomplish these goals, but they’re expensive, call quality is often low, and they’re slow. VoIP (voice-over Internet protocol) is a better option. Scalable, flexible, and fast, it also provides clearer calls and ensures that you have connectivity whether you’re in the office, on the road, or in the field.

The challenge, of course, is choosing between the various VoIP phone providers for law firms. Solo attorneys, small firms, and even growing legal offices must strike the right balance between features and affordability. And if you’ve never used a VoIP provider before, you probably have quite a few questions.

In this guide, we’ll look at 10 of the best VoIP providers for law firms specifically, and we’ll talk a little more about how to choose the best provider for your legal practice, no matter what you have in mind. 

The benefits of VoIP

Before we dive too far into the comparison of the best VoIP phone providers for law firms, let’s consider the benefits the technology offers in the first place. With a VoIP phone provider, your law firm can enjoy:

  • Cost savings when compared to costly landlines
  • Accessibility from any Internet-connected device, anywhere, at any time
  • Add or remove modules and features to suit your needs as your practice grows
  • Access powerful capabilities, including conference calling, voicemail transcription, and more
  • Integration with your legal technology stack for seamless operation and communication
  • Time tracking baked right into the VoIP platform’s software to capture more billable hours

However, all of the VoIP services out there have their own features and pros and cons to consider. Making an informed decision here is critical, which is why we’ve broken down our VoIP comparison to make it easier for you to make an informed choice.

Podium is technically a lead management platform, but the company does offer a robust VoIP solution that promises to help you “stop wasting time managing outdated phone systems. ”Podium Phones (the VoIP offering) is designed specifically for small businesses, which makes it a great choice for solo attorneys and small but growing firms. You can route all calls to the same inbox where you get social media messages, text and MMS messages, and other communications, so you keep messaging cohesive.

There are plenty of other services and features to love. Clear customer messaging history, consolidated calls and messages, and at-a-glance details make this a must-have for most law firms. However, there are more robust options out there, and because Podium is designed for small businesses, it’s not as scaleable as some, meaning that you may outgrow it at some point.

Features to consider with Podium Phones include:

Ooma is changing the way that you think about VoIP services. They have made several of the “best” lists over the past few years for their plans and solutions, for which there is a lot to offer. They start with basic plans that offer simple features for an affordable price, and mobile and desktop apps are available. 

We like that this platform integrates with Amazon Echo and Google Nest. Perhaps the best feature about this VoIP provider, though, is that they offer a 30-day money-back guarantee. You can choose an Ooma subscription, or you can buy an Ooma device and get basic access for free, but most law firms find subscription plans with their own devices more useful.

There’s more to love about OpenPhone, too. You can have additional numbers if necessary for $5 per number per month, for instance. You can also store all your contacts and their associated information in one place.
