The Best Premium VoIP Services for Enterprise
Using an effective VoIP system can mean huge savings for a company on phone expenses, and most top VoIP systems include a host of features that can make your company run smoother.

With enterprise VoIP, we’re talking about VoIP solutions that are tailor-made for large organizations with major telecommunications needs. Enterprises need VoIP solutions that can be easily scaled as the company grows (or shrinks) without any of the red tape of the old phone services. Such companies can specifically benefit from features like video conferencing, call analytics, routing, and international call rates. Also, companies on this scale can benefit a great deal from the fact that most VoIP services offer free communication within a company’s network.

Here are 5 of the best VoIP systems for enterprise that deliver savings, loads of features, and high-quality sound and security:

Even at its most basic plan, RingCentral offers full call management including advanced call forwarding, call screening, unlimited video conferencing with screen sharing, multi-level auto attendant, and the ability to send and receive texts from your company’s business number.

The service is also fully mobile-ready, meaning you can access it remotely and work from anywhere.

When it comes to integrations, RingCentral works with Outlook, Oracle, Zendesk, Box, Google, Salesforce, Okta, and more, though some integrations may require paying for an add-on.

While the enterprise package is the best plan for an enterprise level business, if your company isn’t especially large, then RingCentral’s premium package may be enough.

The premium package costs $34.99/month per user, while the enterprise package is $44.99/month per user. With the enterprise package you get 10,000 toll free minutes as opposed to only 2,500 with premium, as well as the ability to host 75 people in video meetings, as opposed to a maximum of 50 with the premium package. Other than that, the only other feature that enterprise provides which is lacking in premium is voicemail to text.

“A full range of Fortune 500 features” is a hell of a claim, but 8x8 provides a long list of features in a top-of-the-line enterprise VoIP package that can back it up. The “Virtual Office X8” package is what 8x8 refers to as “truly unified.” It’s a unified communication package that combines a cloud-based phone system, conference meetings, and a contact center, suited for large businesses.

8x8’s Virtual Office Analytics Suite provides businesses with an overview of their phone usage, to let you know when quality is best, when they are using the most lines, how many calls are lost and how many returned. The 8x8 virtual office mobile app makes the service accessible to you on mobile devices, and whatever platform your company is using, you can rest a little easier knowing that 8x8 has 99.9983% uptime.

That said, 8x8’s customer service does not include a 24/7 live chat or help line, and there are limited call queuing options.

OnSip VoIP offers enterprise solutions that can save big companies money and improve efficiency. In recent years the company has racked up a number of big name clients like Tumblr and Mozilla, proving that it can handle major enterprise clients.

OnSip comes with many of the standard features you’d expect from a VoIP system, like auto attendant, free on network calling, and a mobile app, but there are dozens of other features available, including third-party softphone integration, SIP domain hosting, and developer API, among others.

It also has extensive integration potential, including Zendesk, Slack, Outlook and Google Analytics.

The pricing system for OnSip is rather unique. It doesn’t require a contract and you basically pay as you go based on which features you want. For one thing, internal calling is free, so you only pay for external calls made and cloud phone system apps used. For another, since no contracts are required, you can change plans or opt out whenever you want without consequences.

Features to look for in enterprise VoIP providers

  • VoIP must be scalable so that it can be fit to any size business from small to large
  • Flexible pricing
  • Video conferencing w/screen sharing
  • Ease of operation
  • Affordable international call rates
  • Pricing plans that include free calls within network
  • High quality audio and no dropped calls
  • Simultaneous, no-delay calling between phone lines in far apart locales

The VoIP industry includes a wide variety of providers for all types of customers. VoIP initially started out as a service solely for residential customers looking to slash their phone costs. In time, VoIP providers realized how lucrative it could be to sell their services en masse to big companies who have far more to gain from cutting their phone costs. Some of the options listed below include major industry leaders like Vonage and RingCentral, and lesser-known companies like Lightspeed and Jive that offer solid VoIP service in their own rights. While most of these companies still offer VoIP service for residential customers, they’re focused more heavily on enterprise business customers who are in the market for much bigger purchases.


Like with residential VoIP or small business VoIP, there’s no single solution or product that will work for every enterprise business. When considering which enterprise VoIP system to purchase, first consider your company’s needs and budget. Every option will be scalable with some sort of mobile access. If the cost is the deal maker, then take some time to crunch the numbers and figure out the return on investment after paying for hardware and monthly service - only then will you know if the monthly savings on your phone bill are worth it.

Otherwise, there are some services which offer more integrations, or include advanced features which require an extra charge with other providers. Take some time to look at some of the best VoIP providers on the market and see what they have to offer.
