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).

There are some solutions to this issue if you have concerns. The most obvious is to utilize Uninterruptable Power Supplies (UPS) for those short outages, or a generator if you live somewhere where outages are more common (and for your fridge!). With so many people having cell phones these days most people will not be too concerned with this issue, especially when they consider the money they are saving. Most services include a call forwarding feature so you can always set that up to go to your cell phone so you do not miss important calls.
Your IT staff will understand the basics of what needs to be done before a VoIP system can be selected and installed. That will include capacity testing on your current pipes and a thorough audit of your organization's network management capabilities to make sure they can support and secure the new flow of VoIP data. But for business-level users, selecting a phone system that will help them keep their various processes moving forward, especially the customer-facing ones, starts with understanding what VoIP really is.
For larger systems, and for systems where security is critical, the old internet connection is no longer adequate. The internet doesn't do quality of service (QoS), and bandwidth can be unpredictable. Network congestion can ruin a business phone call, and activities such as DNS hijacking can put your business at risk. While we all love the internet, it's not necessarily the safe place for your business voice communications. If you fall into this category, remember that while the internet runs using the IP protocol and VoIP runs over the IP protocol, that doesn't mean that VoIP must run over the internet. You can get the same software benefits of VoIP by running your voice network over dedicated lines. Sure, it will cost more, but it will also ensure crystal clear voice quality as well as the ability to implement much-improved data security.
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.
IP communication provides for device mobility. For example, a residential broadband connection may be used as a link to a virtual private network of a corporate entity, in which case the IP address being used for customer communications may belong to the enterprise, not being the IP address of the residential ISP. Such off-premises extensions may appear as part of an upstream IP PBX. On mobile devices, e.g., a 3G handset or USB wireless broadband adapter, the IP address has no relationship with any physical location known to the telephony service provider, since a mobile user could be anywhere in a region with network coverage, even roaming via another cellular company.
Voicemail routing can take multiple forms, but they're basically rules you can apply to incoming calls that will automatically route them to voicemail without even causing a ring. For example, if calls come in with Caller ID blocked, those can be routed directly to voicemail. Or if you're simply not into talking to anyone, you can hang out a digital Do Not Disturb sign and route all calls to voicemail, perhaps until you're feeling more social or every day between the hours of 9 PM and 7 AM. 
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.
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.

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.

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.

Mass-market VoIP services use existing broadband Internet access, by which subscribers place and receive telephone calls in much the same manner as they would via the public switched telephone network (PSTN). Full-service VoIP phone companies provide inbound and outbound service with direct inbound dialing. Many offer unlimited domestic calling and sometimes international calls for a flat monthly subscription fee. Phone calls between subscribers of the same provider are usually free when flat-fee service is not available.[citation needed]

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.
VoIP transforms outgoing or incoming calls into a digital signal and sends it through the internet, converting it to a standard telephone signal to reach a non-VoIP number. This allows you to receive business calls on your personal mobile device. You can even make calls through your VoIP provider’s app on your smartphone—and you won’t have to worry about clients ignoring your call since their caller ID will register your business number instead of your personal number.

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.
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.
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]

The technical details of many VoIP protocols create challenges in routing VoIP traffic through firewalls and network address translators, used to interconnect to transit networks or the Internet. Private session border controllers are often employed to enable VoIP calls to and from protected networks. Other methods to traverse NAT devices involve assistive protocols such as STUN and Interactive Connectivity Establishment (ICE).
In the European Union, the treatment of VoIP service providers is a decision for each national telecommunications regulator, which must use competition law to define relevant national markets and then determine whether any service provider on those national markets has "significant market power" (and so should be subject to certain obligations). A general distinction is usually made between VoIP services that function over managed networks (via broadband connections) and VoIP services that function over unmanaged networks (essentially, the Internet).[citation needed]
(e) In India no Separate Numbering Scheme is provided to the Internet Telephony. Presently the 10 digit Numbering allocation based on E.164 is permitted to the Fixed Telephony, GSM, CDMA wireless service. For Internet Telephony the numbering scheme shall only conform to IP addressing Scheme of Internet Assigned Numbers Authority (IANA). Translation of E.164 number / private number to IP address allotted to any device and vice versa, by ISP to show compliance with IANA numbering scheme is not permitted.
Unlike traditional telephone lines, VoIP numbers can’t be traced by 911 operators. This doesn’t mean you’d be helpless in case of a natural disaster or Sasquatch attack, however. Upon initial setup at a location, you simply need to enter your info manually through the system’s E911 (Enhanced 911) feature, which will attach a physical address to your VoIP number.
A high speed Internet connection is required to "carry" your calls so if you have an Internet outage (or your ISP has an outage) then your phone service will not work. Internet services have improved significantly in the last few years and outages tend to be much less common than they use to be. Again, if you have a cell phone then this may not be an issue for you.
