An IP phone or VoIP Adapter (ATA) – You’ll see a wide range of prices between the different providers when it comes to equipment. Some providers have expensive equipment and “freemium” service; others will lease you equipment for free and charge more per month. Between those two, you have a lot of in-between. An IP phone plugs directly into your modem or router, and an ATA lets you use a legacy phone over the VoIP network. You need an IP phone to truly enjoy all the benefits of VoIP calling, which is why VoIP phones are becoming more popular.

That's the basics of UCaaS, but the concept is constantly evolving to include more communication and collaboration technologies. Those capabilities also get tweaked to provide new benefits, sometimes general, sometimes aimed at specific business use cases, like call centers or help desk operations, for example. The key is integration. Voice is becoming integrated with other back-end apps.
A voice call originating in the VoIP environment also faces challenges to reach its destination if the number is routed to a mobile phone number on a traditional mobile carrier. VoIP has been identified in the past as a Least Cost Routing (LCR) system, which is based on checking the destination of each telephone call as it is made, and then sending the call via the network that will cost the customer the least. This rating is subject to some debate given the complexity of call routing created by number portability. With GSM number portability now in place, LCR providers can no longer rely on using the network root prefix to determine how to route a call. Instead, they must now determine the actual network of every number before routing the call.[citation needed]

In the case of a private VoIP system, the primary telephony system itself is located within the private infrastructure of the end user organisation. Usually, the system will be deployed on-premises at a site within the direct control of the organisation. This can provide numerous benefits in terms of QoS control (see below), cost scalability, and ensuring privacy and security of communications traffic. However, the responsibility for ensuring that the VoIP system remains performant and resilient is predominantly vested in the end user organisation. This is not the case with a Hosted VoIP solution.


On 24 March 2020, the United Arab Emirates loosened restriction on VoIP services earlier prohibited in the country, to ease communication during the COVID-19 pandemic. However, popular instant messaging applications like WhatsApp, Skype, and FaceTime remained blocked from being used for voice and video calls, constricting residents to use paid services from the country’s state-owned telecom providers.[60]
While there are still a few other legacy protocols around, and a few non-SIP standards, such as H.232, SIP is what's used for the vast majority of modern VoIP phone systems. The most common use I've seen for H.232 has been in dedicated video conferencing systems. SIP, meanwhile, handles phone service, video conferencing, and several other tasks just fine, which is why its use is so widespread. Where it has trouble is with data security, but more on that in a bit.

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.
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]
However, VoIP traffic to and from the on-premises systems can often also be sent over secure private links. Examples include personal VPN, site-to-site VPN, private networks such as MPLS and SD-WAN, or via private SBCs (Session Border Controllers). While exceptions and private peering options do exist, it is generally uncommon for those private connectivity methods to be provided by Hosted or Cloud VoIP providers.
When you're considering a new VoIP phone system for your business, it's important to include stakeholders from all of the key parts of your business in the planning and decision making process. Yes, this especially includes the IT staff and the data security folks since your voice communications will now be data. But it also needs to include folks who will be using the system to get work done, especially the work that drives revenue and engages customers. These people have invaluable insights into what's really needed versus what's simply cool and new. Plus, you'll need their input to select a phone system that will actually move your business forward as well as fit into your IT environment.
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.
Similar to Ooma's residential service (below), AXvoice deploys its home VoIP with the help of an appliance, appropriately called the AXvoice Device, which sits between your home's phones and your Internet router. This device not only serves as a bridge between your old phones and the new VoIP service it also enables many of the advanced features that straight POTS bridges often don't address.
In the United States, the Federal Communications Commission requires all interconnected VoIP service providers to comply with requirements comparable to those for traditional telecommunications service providers.[64] VoIP operators in the US are required to support local number portability; make service accessible to people with disabilities; pay regulatory fees, universal service contributions, and other mandated payments; and enable law enforcement authorities to conduct surveillance pursuant to the Communications Assistance for Law Enforcement Act (CALEA).

Signaling – Performing registration (advertising one's presence and contact information) and discovery (locating someone and obtaining their contact information), dialing (including reporting call progress), negotiating capabilities, and call control (such as hold, mute, transfer/forwarding, dialing DTMF keys during a call [e.g. to interact with an automated attendant or IVR], etc.).
Typically, price is one of the most important reasons people opt for residential VoIP. One of the most attractive is the "triple play" sales pitch we mentioned above made by almost every regional residential cable company and internet provider: Get your Internet, TV, and phone service all rolled into one monthly charge. Not only is that usually an attractive number, it also means a technician will hook everything up for you including your phone, and you'll probably be able to use the same phone you're using now instead of having to migrate to a VoIP phone.

On the customer service front, RingCentral receives mostly positive reviews, offering phone assistance during standard work hours, 24/7 online chat service, and ticket service, in addition to weekly webinars and an extensive online knowledge base. Businesses of 20 users or fewer should note, however, that RingCentral favors larger enterprises for US-based support and outsources smaller-office support overseas.
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).

VoIP or Voice over Internet Protocol, is a phone service that operates over the Internet. It creates a digital signal from an incoming or outgoing call. After this, it converts that signal to reach members who are not using VoIP. This cloud-based solution allows you to receive calls from a VoIP phone, any phone with a VoIP adaptor, mobile hotspot, or computer.

Choose the service that is appropriate for your calling needs. Residential VoIP plans are cheaper than business VoIP plans because: (1) they have fewer features and (2) residential phones are used less frequently than business phones. Don’t use a residential VoIP service for a home-based business unless you’re willing to pay overage fees or to have your VoIP service canceled. VoIP providers are serious about enforcing their Fair Use guidelines.

If that all is starting to sound more complex than it's worth, remember that turning your PBX into a software solution means significant opportunity for flexibility and integration that you simply can't get any other way. After all, programmers can now treat your phone like an app. Where that's taken us is to the fast-changing UCaaS paradigm (more on that below). Here, traditional VoIP providers, like the ones we review as part of this review roundup, provide additional software capabilities that are all implemented and managed from a single, unified console.
