The caveat there is the proverbial fine print, usually located just below the really attractive dollar figure. This small print generally details exactly how many months that nice number will remain in effect before the bloom comes off the rose and you start getting billed a much higher number that represents the service's actual cost. Many providers don't even print this higher number on their websites, so be sure to ask the sales guy on the phone before you sign up. The nice number that pulled you in can often double or more once the introductory period wears off. Some providers even attach a minimum length of time that you'll need to suffer these higher costs before you can change or modify the service without getting hit with an additional early-termination penalty fee.
However, for many businesses there's a need to route calls to the PSTN and other analog phones that might remain in use, too. This may mean a PSTN gateway, or even a hybrid PBX, where there's at least a small telephone switch located on-site. Note that these days, a PBX looks exactly like the other servers in your data center, except with an attached means of handling local and analog phones. Many small businesses, however, are avoiding on-premises PBXes partially due to cost savings and partially because the capabilities offered by all-cloud systems are more than advanced enough for their needs. Some virtual cloud PBXes can handle PSTN connectivity without on-site hardware requirements.

While understanding the basics of VoIP and SIP is important, setting one of these systems up will require some general network knowledge, too. For the best quality, you will need to meet a minimum upstream and downstream data throughput requirement. In addition, you'll also need to meet a minimum latency number (that is, the time between when a signal leaves a remote computer and when your system receives it), typically measured in milliseconds. It is possible to test your network connection to see if it will support a VoIP service. RingCentral offers this service from their website, other vendors like to have their service engineers do it for you.  
The problem there is that VoIP traffic is much more sensitive to network bumps and potholes than most general office traffic. That translates to conversations breaking up or cutting out entirely, difficulty connecting over Wi-Fi, or (worst case) dropped and lost calls. If your business is small and your network is essentially contained in one or two wireless routers, then your configuration and testing headaches might be fairly small (though still there). But for medium and larger networks, these tasks can not only be complex, but also time consuming, which translates into added cost in terms of man-hours.

Step 3 is all about reviews. However, as this section is about comparison we are introducing our Ratings Comparison Tool in this section. This tool allows the ability to select from a list of service providers and compare user review ratings side by side. You can also select specific rating categories for a seletion of providers and visually compare in a graphical representation.

The service's we detail below, however, aren't triple play providers. Every service detailed here is an independent residential VoIP provider that you can use over any broadband internet connection. But while that means their pricing is probably somewhat more transparent than in a triple play scenario, some of them do still obscure the real number you'll wind up paying. This can happen in several ways.


PhonePower is one of a handful of VoIP providers that actually specialize in residential VoIP rather than business VoIP. Although PhonePower has many plans, it’s best for calling within the US (including Puerto Rico) and Canada. That’s because it has possibly the cheapest prices in residential VoIP, providing you’re calling solely on local numbers. PhonePower also enables calls abroad, although there are cheaper options such as Vonage if you’re planning on making more than an hour’s worth of calls internationally each month.

Because they're working across such a multitude of channels, many of today's phone systems are adopting the moniker of Unified Communications-as-a-Service (UCaaS). These are generally cloud-based, virtual PBXes (private branch exchanges) that include at least one, usually multiple, software clients to enhance their functionality on the web, desktop, and a variety of mobile devices. UCaaS systems have a wide variety of feature sets based on the tried and true VoIP. Even residential VoIP systems come with features that are simply impossible using a conventional telephone system.
Be aware, however, that there are significant security implications regarding the use of mobile softphones on employee-owned devices. While it's possible for your employees to simply download the appropriate software from their respective app store, your IT department should be involved with allowing access while also confirming that necessary security steps are taken. Also be aware that there are important reasons not to allow soft phone installations on private devices of any type because you may not be able to remove that phone client if the employee leaves the company, and because local laws may impact how much control you have over the use of the device.

Similar to its popular small business VoIP solution, Ooma Office, the company touts its on-premises VoIP appliance to power its residential service. You'll find three versions of this device to choose from: the Ooma Telo, Ooma Telo Air or Ooma Telo 4G, but they all sit between your Internet router and your phones, making installation of this low-cost service plug-and-play.  

Most of these VoIP solutions will require stable and consistent internet connectivity at every location where wired phones are to be used. At the very least, your business phone system must have access to a business class internet link to the cloud. This should be a dedicated link through a dedicated router if you expect your phone calls to sound as if they were coming from a business and not someone's home Skype connection. But it's important to know that you will also need a router that can create a virtual LAN (VLAN), and one that has the ability to encrypt voice traffic, and only your voice traffic. VoIP security from end to end for all calls is now a business necessity.
Vonage Business is the biggest name in VoIP, and the good news is it’s a leader in residential VoIP too.

Still the pandemic won't last forever so keeping in mind core VoIP criteria is important, too. That means providing voice communications for employees at their desks. VoIP systems may also need to support a call center for sales, customer service, and support; and they often need to connect with and through a host of other communications channels, such as fax machines, video conferencing, conference calling, mobile communications, wireless handsets, and text messaging. On top of that, they're often expected to provide more advanced functionality through software, like shared meeting collaboration, voicemail to email transcription, and call recording. And lest we forget, many businesses still need a service that will connect to public switched telephone network (PSTN).
