Throughout the developing world, particularly in countries where regulation is weak or captured by the dominant operator, restrictions on the use of VoIP are often imposed, including in Panama where VoIP is taxed, Guyana where VoIP is prohibited.[51] In Ethiopia, where the government is nationalising telecommunication service, it is a criminal offence to offer services using VoIP. The country has installed firewalls to prevent international calls being made using VoIP. These measures were taken after the popularity of VoIP reduced the income generated by the state owned telecommunication company.
The following table provides a high level summary of how residential VoIP service compares to other alternative solutions for home phone service. The table compares this service to a regular landline, a bundled phone service from a cable company such as double or triple play, and a cell phone service. The cell phone is included as some people decide to just get rid of their wired phone and use their cell phone for all calls. Free services such as Skype are not included as they are not effective, like for like, landline replacements in our opinion.
In 1999, a discrete cosine transform (DCT) audio data compression algorithm called the modified discrete cosine transform (MDCT) was adopted for the Siren codec, used in the G.722.1 wideband audio coding standard.[74][75] The same year, the MDCT was adapted into the LD-MDCT speech coding algorithm, used for the AAC-LD format and intended for significantly improved audio quality in VoIP applications.[76] MDCT has since been widely used in VoIP applications, such as the G.729.1 wideband codec introduced in 2006,[77] Apple's Facetime (using AAC-LD) introduced in 2010,[78] the CELT codec introduced in 2011,[79] the Opus codec introduced in 2012,[80] and WhatsApp's voice calling feature introduced in 2015.[81]

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]

Another area of business VoIP support covers the growing number of mobile employees using softphones for sending and receiving calls from a laptop or mobile device. With a cloud-based PBX solution, you can have employees at different physical locations, including multiple time zones. This makes it easier to support longer business hours to cover your entire customer base. Most of the business offerings offer call routing based on the time of day and time zone.
A telephone connected to a land line has a direct relationship between a telephone number and a physical location, which is maintained by the telephone company and available to emergency responders via the national emergency response service centers in form of emergency subscriber lists. When an emergency call is received by a center the location is automatically determined from its databases and displayed on the operator console.
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. 
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.

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.
If you want to compare pricing for multiple residential service providers you can use our Home Phone Rates Tool. Please note that the pricing does not include additional fees like sales tax, regulatory fees and any other taxes/fees that may be relevant to your location. These tend to be the same for each provider as it is based on location, however, some providers may include additional "recovery" fees for the overhead involved in state and regulatory compliance (e.g. FCC reporting compliance).
Early providers of voice-over-IP services used business models and offered technical solutions that mirrored the architecture of the legacy telephone network. Second-generation providers, such as Skype, built closed networks for private user bases, offering the benefit of free calls and convenience while potentially charging for access to other communication networks, such as the PSTN. This limited the freedom of users to mix-and-match third-party hardware and software. Third-generation providers, such as Google Talk, adopted the concept of federated VoIP.[1] These solutions typically allow dynamic interconnection between users in any two domains of the Internet, when a user wishes to place a call.

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.
A VoIP media gateway controller (aka Class 5 Softswitch) works in cooperation with a media gateway (aka IP Business Gateway) and connects the digital media stream, so as to complete the path for voice and data. Gateways include interfaces for connecting to standard PSTN networks. Ethernet interfaces are also included in the modern systems which are specially designed to link calls that are passed via VoIP.[26]

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.
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.

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.

In the following time span of about two decades, various forms of packet telephony were developed and industry interest groups formed to support the new technologies. Following the termination of the ARPANET project, and expansion of the Internet for commercial traffic, IP telephony was tested and deemed infeasible for commercial use until the introduction of VocalChat in the early 1990s and then in Feb 1995 the official release of Internet Phone (or iPhone for short) commercial software by VocalTec , based on the Audio Transceiver patent by Lior Haramaty and Alon Cohen, and followed by other VoIP infrastructure components such as telephony gateways and switching servers. Soon after it became an established area of interest in commercial labs of the major IT concerns. By the late 1990s, the first softswitches became available, and new protocols, such as H.323, MGCP and the Session Initiation Protocol (SIP) gained widespread attention. In the early 2000s, the proliferation of high-bandwidth always-on Internet connections to residential dwellings and businesses, spawned an industry of Internet telephony service providers (ITSPs). The development of open-source telephony software, such as Asterisk PBX, fueled widespread interest and entrepreneurship in voice-over-IP services, applying new Internet technology paradigms, such as cloud services to telephony.
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/

Though many consumer VoIP solutions do not support encryption of the signaling path or the media, securing a VoIP phone is conceptually easier to implement than on traditional telephone circuits. A result of the lack of encryption is that it is relatively easy to eavesdrop on VoIP calls when access to the data network is possible.[38] Free open-source solutions, such as Wireshark, facilitate capturing VoIP conversations.
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]

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.

A telephone connected to a land line has a direct relationship between a telephone number and a physical location, which is maintained by the telephone company and available to emergency responders via the national emergency response service centers in form of emergency subscriber lists. When an emergency call is received by a center the location is automatically determined from its databases and displayed on the operator console.
The majority of plans are loaded with a great selection of features that can come in handy when you are making or receiving calls. Many providers offer over 30 features included in the low monthly fees. These include basic call management features such as call waiting, call forwarding, call blocking, caller ID name, do not disturb, and voicemail. More advanced features such as the voicemail to email feature let's you access your messages at anytime, even when you are away from your home, simply by checking your email inbox. Distinctive ringing, additional virtual numbers, and Smartphone Calling App's are other examples of more advanced features that can be useful.
