1992: InSoft Inc. announces and launches its desktop conferencing product Communique, which included VoIP and video.[85] The company is credited with developing the first generation of commercial, US-based VoIP, Internet media streaming and real-time Internet telephony/collaborative software and standards that would provide the basis for the Real Time Streaming Protocol (RTSP) standard.[86][87]
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.
To get a better picture of the savings of VoIP for home use, here's a real life example: Long distance calls with a VoIP provider can be as little as $10 per month, if not less. Major telecommunications corporations typically charge more for such packages, even 2 or 3 times as much. If you look at this over the course of a year, that’s no small change.  
E911 (Enhanced 911) is a little different to traditional 911 services and is something that you should be aware of. With E911 you need to provide your home address, and this information gets passed to the emergency services if you dial 911. The concerns are that if you have a power outage or an Internet outage then you will not be able to dial 911. If you have a cell phone then you can dial 911 from your device. If you are ONLY reliant on VoIP for your phone service you should be aware of this situation.
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.

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/
Like the rest of us, you probably don't like to get hassled with unwanted phone calls when you’re at home. You can also implement “enhanced call forwarding” to reroute and block the numbers that you specify, without the caller having any idea. You also can set up your phone to block international and directory assistance calls, so they don’t bother you at home. 
An important disadvantage of the landline is that you cannot easily scale it up or down. This is why many companies with rapidly expanding or contracting business sizes prefer VoIP because it allows enterprise management to easily add, edit or even delete user rights centrally through the control panel. It is not necessary to follow the tedious processes involved if you are using a regular landline. This makes internet phone technology significantly more suitable for large business organizations.

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.
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).
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]
Our real estate investment company has 14 phone lines altogether. For a phone service, we needed a local number, good call quality, uninterrupted service, calling apps for our laptops and cell phones, and an internal messaging platform for team communication. We started out with a niche company called Sound Communications, but their call quality and app were not very good. So once we made a bit more income, we decided to switch to RingCentral. RingCentral provides great call quality and is highly recommended in the real estate investment community. They are on the pricier side—$419.88 per line per year—but I’m OK with the price because their service is worth it and the high-quality phone calls are very important to our business.

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.
Phone Power is another home VoIP provider that runs its service using an on-premises device. This is called the Home Adapter and like other services, it sits between your phones and your Internet connection, though no other network is required. It can even function as a router on its own. While it's not the cheapest home VoIP solution we found, it's certainly well-regarded and mature with a wide variety of options and capabilities.

On the early ARPANET, real-time voice communication was not possible with uncompressed pulse-code modulation (PCM) digital speech packets, which had a bit rate of 64 kbps, much greater than the 2.4 kbps bandwidth of early modems. The solution to this problem was linear predictive coding (LPC), a speech coding data compression algorithm that was first proposed by Fumitada Itakura of Nagoya University and Shuzo Saito of Nippon Telegraph and Telephone (NTT) in 1966. LPC was capable of speech compression down to 2.4 kbps, leading to the first successful real-time conversation over ARPANET in 1974, between Culler-Harrison Incorporated in Goleta, California, and MIT Lincoln Laboratory in Lexington, Massachusetts.[71] LPC has since been the most widely used speech coding method.[72] Code-excited linear prediction (CELP), a type of LPC algorithm, was developed by Manfred R. Schroeder and Bishnu S. Atal in 1985.[73] LPC algorithms remain an audio coding standard in modern VoIP technology.[71]
Let’s face it: the office environment isn’t for everyone.

Back-end integration with custom and third-party apps, like CRM systems, also open a whole new world for your calling data because now it can extend the phone system beyond just basic voice communication. Such integrations allows users to transfer calls to and from their mobile phone, place and receive calls from their personal phone (that appear to be coming from the business), and interact with colleagues and customers via voice and text -- all from a variety of devices. But it also allows recording and analysis of call data to measure things like customer satisfaction, understand your sales audience at a new level, and even handle customer requests and problems automatically without the customer ever being aware they never spoke to a human.

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.
In general, the provision of VoIP telephony systems to organisational or individual users can be divided into two primary delivery methods: private or on-premises solutions, or externally hosted solutions delivered by third-party providers. On-premises delivery methods are more akin to the classic PBX deployment model for connecting an office to local PSTN networks.

VoIP service simply enables your phone calls to be transmitted and received over your home Internet connection instead of your telephone landline. This is perhaps why some people refer to the service as being an Internet phone service or broadband phone service. This does mean though that you need a high speed Internet service to be able to use VoIP for your phone service.
