The complexity of the business telephony market is nothing short of staggering. With hundreds of differences—some minor, some major—in technology, features and usability, buying a new VoIP phone system can get very confusing very quickly.
We’ve written this buyer’s guide to make business telephony a little easier to understand, and to make the buying process a little more palatable. Here’s what we’ll cover:
Reviewers' Choice Products
|Vonage Business Solutions|
Our Reviewers’ Choice list shows the five highest user-rated software solutions for VoIP when adjusted for total number of reviews and recency of reviews.
If a software solution has more reviews, and more recent reviews, we value those ratings more highly than a product with fewer, older reviews. This is because is it much harder to get 100 five-star reviews than it is to get 10.
We also know that software vendors continually tweak and update their product, so we believe that more recent reviews tend to be more accurate.
To determine which products made the final cut, we looked at how users rated each solution's:
A solution can make the Reviewers' Choice top five in all three categories, or just one or two. All software solutions in the Reviewers' Choice have at least 10 reviews from real software users. The final products are listed in alphabetical order from left to right.

Traditional business phone systems use the traditional landline telephone system, often called the Plain Old Telephone Service or POTS. VoIP phone systems, discussed below, use the Internet instead of the POTS. Overall, the technology is in a state of transition from traditional to VoIP, and many businesses have phone systems using elements of both.
Private Branch Exchanges (PBX)
In a PBX system, every office phone is connected to a single, centralized router within the office, which then assigns a unique line (called a trunk) to the public telephone network. A PBX allows internal calls to be routed without connecting to the public phone network at all—translating to significant cost savings, particularly in large offices.
The term "PBX" originates from the days when a live operator manually connected lines (exchanging branches) at a company’s internal switchboard. Though today’s technology is wildly different (there aren’t always branches, nothing’s being exchanged and the business phone system is often managed remotely, which means it’s not even private anymore), the term is so widespread in the industry that it is still used to describe any in-house office phone system. Related acronyms you might hear include:
In a key system, the user selects the line manually, with lights indicating which lines are in use. Though this is a useful feature for small office systems, it quickly becomes impractical as the number of users grows. (Imagine a key system with 50 lines.)
As technology has improved, a hybrid model has emerged that routes keyed phones through an electronic system, similar to a PBX. This has allowed for the rapid merging of keyed and PBX features, plus the development of new features such as:
Though this description drastically oversimplifies all that goes into the technology, what’s important to note is that most keyed systems today operate through some form of hybrid model.
Choosing Between a PBX and a Hybrid Key System
Though these technologies have converged over time, their usability and features make them very different at the user level. Since a modern PBX control unit is essentially a specialized computer, it provides automated call distribution and many more features associated with computer telephony integration (CTI, described in more detail below). The behavior of a hybrid key system, however, may be far more preferable (and more cost-effective) for smaller businesses that don’t need those features or more than a dozen or so lines.
|Line selection||User selects the line, or the system defaults to the first available line.||User dials an “escape number” (usually 9, in the U.S.) to access an outside line. (Note that modern systems can often bypass this step through software that recognizes how calls should be routed based on the first number or numbers.)|
|Inbound calls||Can be answered by multiple people. Often, the phone will ring simultaneously at multiple endpoints, and whomever answers first gets it.||Calls are routed to a specific user, often automatically to the first available user of a specified type.|
|Ideal for||>50 employees and/or call centers|
Voice over Internet Protocol, or VoIP, sends communication data through the Internet rather than through a traditional phone line. The biggest benefit of VoIP telephone syste
