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. 

The Yealink Touch-sensitive HD IP Conference Phone CP920 is comprised with the Android 5.1 operating system.

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.  
That situation is for fairly pristine network and business conditions, however. Companies with legacy equipment or unique business needs may need a hybrid PBX, in which a portion of the voice network remains in the analog world, while the rest is converted to cloud-based VoIP. This could happen if you occupy an older building without the necessary Ethernet infrastructure to support VoIP or if you had custom software built a long time ago that simply isn't compatible with newer phone technologies.
Companies working from home will appreciate Ooma’s remote features. For starters, Ooma offers a mobile app that lets you make and receive calls from your smartphone using your business number. You can also set up ring groups, which allows you to group extensions together so they all ring simultaneously—then the call gets transferred to whichever remote employee picks up first.
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.

Fortunately, most of the providers reviewed here have engineering staff that will contact you as part of your setup process to help your IT staffers test and optimize your network prior to deploying their solutions. That's definitely something we recommend, but there are steps you can take now to prep your LAN for VoIP and make the deployment process that much easier.


The SIP-T42S IP phone is a dynamic business communications tool for superior voice communications and extended functionality. The SIP-T42S is a 12-line IP phone with multiple programmable keys for enhancing productivity. It is with Yealink Optima HD Voice Technology and wideband codec of Opus for superb sound quality and crystal clear communications. It’s built with Gigabit Ethernet technology and with an all-new USB port, the SIP-T42S boasts unparalleled functionality and expansibility with Bluetooth, Wi-Fi and USB recording features.
Private VoIP systems can be physical hardware PBX appliances, converged with other infrastructure, or they can be deployed as software applications. Generally the latter two options will be in the form of a separate virtualised appliance. However in some scenarios, these systems are deployed on bare metal infrastructure or IoT devices. With some solutions, such as 3CX, companies can attempt to blend the benefits of hosted and private on-premises systems by implementing their own private solution but within an external environment. Examples can include datacentre collocation services, public cloud, or private cloud locations.
While the exact features offered in any particular UCaaS solution can change radically from vendor to vendor, most include options for video conferencing, shared meeting and document collaboration tools, integrated faxing, mobile VoIP integration, and device-independent softphone clients. All of these options let customers look at communications in a whole new way, namely, in an a menu-style manner where they can implement only those features their business needs and then access them any time they want and in any combination. This new approach to business communications has been growing steadily among customers over the past few years as recent research from Statista bears out.  
Voice Over IP (VoIP) service is great for both businesses and homes. Whether you live in a small apartment or a three-story house, you can save money and get telephone services you never knew existed. No matter how much they promise, the landline phone companies are still stuck in the twentieth century. They simply can’t compete with the features and prices offered by residential VoIP providers. The traditional phone companies charge you everything from tax, service charges and sometimes the occasional “hidden” fee. Residential VoIP plans and services can cut your home phone bill by an average of 50% every month. With additional internet searches, coupon sites, sign-up bonuses, and monthly specials, you can save even more. Residential VoIP service is a bargain-hunter’s dream. GetVoIP.com can help you find the best home phone provider for your needs.
On the phone providers' side, since this review roundup was first published, some of the products listed here now belong to other companies and some have merged into new products. If you're planning to depend on your phone system over the course of the next decade, then you should consider a vendor that's stable enough to still be around when it's time to up upgrade.

If you're wondering what you get with a softphone that you won't with a standard phone handset, then that depends on the service. Business-class softphones offer all kinds of features related to online meeting collaboration, call routing, multi-line conference calling, and more. From a residential VoIP perspective, you'll most often find video conferencing (though more and more this is becoming a separate product from most providers), a voicemail-to-text converter, detailed call records, and user controls for users other than yourself. Some services also offer faxing, text chat, and call metering so you can see how much you're spending.
To help businesses work from home, RingCentral provides unlimited internet faxing and audioconferencing on all the plans listed above. Video meetings can include up to 100 participants, and meetings can last up to 24 hours—just in case your group needs to burn the midnight oil. Standard plans and higher also include popular communication integrations like 365, G Suite, and Slack.
While we think Grasshopper is great for small businesses, it misses out on our “Best Small-Business Phone Service” title because, compared to Ooma, Grasshopper is a little expensive. Grasshopper plans start at $26 per month, assuming you sign up for annual billing. And starting plans include only one business phone number with up to three extensions.

What makes SIP so popular is not only that it's deep and flexible, but also because it was purpose-built to engage in multimedia (meaning not just audio but also video and even text) communications over TCP/IP networks. For VoIP calls, SIP can set up calls using a number of IP-related protocols, including the Stream Control Transmission Protocol (SCTP), the Transmission Control Protocol (TCP), and the User Datagram Protocol (UDP), among others. But it can also handle other functions, including session setup (initiating a call at the target endpoint—the phone you're calling), presence management (giving an indicator of whether a user is "available," "away," etc.), location management (target registration), call monitoring, and more. Despite all that capability, SIP is simple compared to other VoIP protocols primarily because it's text-based and built on a simple request/response model that's similar in many ways to both HTTP and SMTP. Yet, it's still capable of handling the most complex operations of business-grade PBXes.  
The receiver must resequence IP packets that arrive out of order and recover gracefully when packets arrive too late or not at all. Packet delay variation results from changes in queuing delay along a given network path due to competition from other users for the same transmission links. VoIP receivers accommodate this variation by storing incoming packets briefly in a playout buffer, deliberately increasing latency to improve the chance that each packet will be on hand when it is time for the voice engine to play it. The added delay is thus a compromise between excessive latency and excessive dropout, i.e. momentary audio interruptions.
Few things in life are set in stone, and the same should be true of your VoIP plan. It’s wise to find a plan that is scalable and which you can easily expand if need be. You’ll want to know if you can break your contract early if you find a better deal elsewhere, or if you can easily switch plans with the same company in order to take advantage of more features, or to get rid of some you don’t need. 
Ooma also offers a lot of customer relationship management (CRM) integration features with its Enterprise plans. In other words, you get complete integration of your phone system into your existing customer relationship management software. This allows you to enjoy extra perks like transferring an entire customer workspace whenever you transfer a customer call within your workspace—that way, you don’t lose all the progress you made on your customer’s account just because you have to transfer them to another station.

It gets even better! Calling internationally using VoIP is far less expensive than using a traditional landline phone company. Every region of the world, from Afghanistan to Zimbabwe, has its own combination of technological development, geographic obstacles, regulations, and taxes. Cell phone carriers, much like VoIP providers, have their own network, which is why it usually costs more to call international cell phones. If a VoIP provider has a significant presence in a country, it’s likely that landline calls will be unlimited with an international package. For example, if you are using Vonage Word, calling from the U.S. to a landline in Germany is included, but it costs US$.0061 per minute to call a cellular phone. If you are using ViaTalk World, you can call both German cell phones and German Landlines for the same rate – free up to 1200 minutes per month. Don’t forget that with every VoIP provider, if you call within their own network, calls are always free no matter where you are in the world. With the development of SIP, you can easily make and receive free international calls from your home using VoIP.

We recognize that not all our readers’ businesses are based in the US. So we took another pass at our content to provide more information on each provider’s international offerings. And because 8x8’s international rates on calls made from the US are so good, we bumped it up to our number five spot. Finally, we added info about Ooma’s new plan (Ooma Office Pro) to the offerings mentioned below.
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.
Because of the bandwidth efficiency and low costs that VoIP technology can provide, businesses are migrating from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs. In 2008, 80% of all new Private branch exchange (PBX) lines installed internationally were VoIP.[9] For example, in the United States, the Social Security Administration is converting its field offices of 63,000 workers from traditional phone installations to a VoIP infrastructure carried over its existing data network.[10][11]
By default, network routers handle traffic on a first-come, first-served basis. Fixed delays cannot be controlled as they are caused by the physical distance the packets travel. They are especially problematic when satellite circuits are involved because of the long distance to a geostationary satellite and back; delays of 400–600 ms are typical. Latency can be minimized by marking voice packets as being delay-sensitive with QoS methods such as DiffServ.[16]

GoToConnect has nearly as many glowing critical reviews as the Radiohead discography, minus the pretentious lyricism. GoToConnect has established a positive industry reputation since its launch as Jive in 2006, thanks mostly to its interface simplicity, focus on small businesses, and large array of telephone features that are available to all pricing tiers.
Since Verizon is a massive company, customer service ratings are in line with what you’d usually read in the comments section—meaning, people are far more motivated to complain than praise. Navigating Verizon’s bundling plans for businesses may be like a choose-your-own-adventure odyssey, but its support lines are segregated well, with separate contacts for small, medium, and larger businesses. Verizon also offers competitive SLAs (service level agreements) for quality and service and 24/7 support via phone, email, and tickets.

The relevant EU Directive is not clearly drafted concerning obligations which can exist independently of market power (e.g., the obligation to offer access to emergency calls), and it is impossible to say definitively whether VoIP service providers of either type are bound by them. A review of the EU Directive is under way and should be complete by 2007.[citation needed]

Therefore, VoIP solutions also need to handle MNP when routing a voice call. In countries without a central database, like the UK, it might be necessary to query the GSM network about which home network a mobile phone number belongs to. As the popularity of VoIP increases in the enterprise markets because of least cost routing options, it needs to provide a certain level of reliability when handling calls.

Businesses need a number of phone features to improve their productivity and efficiency. The investment in achieving this with a fixed landline service is high, while many VoIP providers offer many of these features for free. Even for the more advanced services paid for, a VoIP service costs significantly less than a regular landline phone service. https://www.lascomsolutions.co.uk/
This VoIP phone system for small business focuses primarily on delivering solutions for businesses operating on their mobile devices. Mitel plans start at $20.99 per month per line, which includes unlimited minutes, audioconferencing, videoconferencing, and integrations with Outlook and G Suite. Plus, Mitel is offering free service until 2021 to help businesses deal with the effects of coronavirus.
In Oman, it is illegal to provide or use unauthorized VoIP services, to the extent that web sites of unlicensed VoIP providers have been blocked. Violations may be punished with fines of 50,000 Omani Rial (about 130,317 US dollars), a two year prison sentence or both. In 2009, police raided 121 Internet cafes throughout the country and arrested 212 people for using or providing VoIP services.[53]
For an extremely small business, especially one that’s just starting out, Ooma is a smart choice, as it provides all of the hardware and software you need to be up and running quickly. You don’t need a lot of know-how to start using Ooma, which is nice for a small business, where the owner likely has to wear numerous hats, including network management.

Now that so many people are working from home, keeping your business' voice communications organized and centralized can be tricky. Fortunately, that's where cloud-served voice over IP (VoIP) providers can shine. With cloud VoIP (sometimes called a cloud PBX system), you can move direct extensions to new geographical locations simply by clicking a mouse. Devices can also change with similar ease either with a software download or simply by re-configuring call forwarding. With many of these systems also adding a wide variety of team collaboration features, cloud VoIP is probably the best COVID-19 investment a business can make.
