Early providers of voice-over-IP services used business models and offered technical solutions that mirrored the architecture of the legacy telephone network. Second-generation providers, such as Skype, built closed networks for private user bases, offering the benefit of free calls and convenience while potentially charging for access to other communication networks, such as the PSTN. This limited the freedom of users to mix-and-match third-party hardware and software. Third-generation providers, such as Google Talk, adopted the concept of federated VoIP.[1] These solutions typically allow dynamic interconnection between users in any two domains of the Internet, when a user wishes to place a call.
Communication on the IP network is perceived as less reliable in contrast to the circuit-switched public telephone network because it does not provide a network-based mechanism to ensure that data packets are not lost, and are delivered in sequential order. It is a best-effort network without fundamental Quality of Service (QoS) guarantees. Voice, and all other data, travels in packets over IP networks with fixed maximum capacity. This system may be more prone to data loss in the presence of congestion[a] than traditional circuit switched systems; a circuit switched system of insufficient capacity will refuse new connections while carrying the remainder without impairment, while the quality of real-time data such as telephone conversations on packet-switched networks degrades dramatically.[16] Therefore, VoIP implementations may face problems with latency, packet loss, and jitter.[16][17]
It's also critical that you consider the impact of mergers and acquisitions on your phone system, both from your own organization's perspective as well as your VoIP provider. Because VoIP systems turn calls into data, the whole process isn't as plug-and-play standards-based as the old-fashioned analog phone system might have been. Should your company merge with or purchase another, VoIP compatibility will become another significant IT issue.
The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 gigabit per second) Local area network (LAN) using existing home wiring (power lines, phone lines and coaxial cables). G.hn provides QoS by means of Contention-Free Transmission Opportunities (CFTXOPs) which are allocated to flows (such as a VoIP call) which require QoS and which have negotiated a contract with the network controllers.

Sometimes things don’t go exactly according to plan and it’s good to have all your bases covered. Check if the company you’re signing with has a money-back guarantee and to what extent they back up their promises. You should also favor one that has multiple avenues for customer service—around the clock if possible—and read online reviews about the customer service the company provides.
If you want to compare pricing for multiple residential service providers you can use our Home Phone Rates Tool. Please note that the pricing does not include additional fees like sales tax, regulatory fees and any other taxes/fees that may be relevant to your location. These tend to be the same for each provider as it is based on location, however, some providers may include additional "recovery" fees for the overhead involved in state and regulatory compliance (e.g. FCC reporting compliance).
RingCentral’s VoIP service isn’t the cheapest option right out of the box, but it does include features that other providers charge extra for (such as generous toll-free minutes and unlimited video conferencing). Plus, RingCentral offers price matching on plans with less than 50 lines, so you can rest easy knowing you’re getting the best possible price for your service.
Figure out how much you’re willing to spend on your VoIP and this will help you better hone in on the company that’s right for you. Your residential VoIP should cost less than your current landline, but it’s still smart to do some price comparison and see which companies offer special deals (for instance, many companies will offer you a better rate if you sign up for a year plan rather than a month-to-month plan). Take a look at your monthly phone bill and the features you’re paying for, and compare that side-by-side with what you’d be signing up for with a VoIP plan. 
Setting up a residential VoIP system can mean big savings on your phone bill, especially if you make a large number of long distance and international calls. In addition, these systems are mobile-optimized, and provide a wealth of features that may just change the way you think of your home phone service. Take a look at the features you need and the budget you can handle, and make the decision that’s right for you.
One of the most exciting and clear differences between a cloud PBX provider and a standard telephone system is software. Your IT staff will find a host of new software tools to help monitor and manage the system. But what catches most business operators' eyes are two key capabilities that software provides: back-end integration and softphones. The latter is exactly what the name implies, a phone that's rendered entirely in software allowing any compatible device to become a phone as long as it has an internet connection, a speaker, and a microphone. More on that below.
