It is much cheaper than a regular landline - most providers offer unlimited calling plans (including long distance) in the USA and Canada for under $10 per month. There are also some great promotional deals available such as 2 year specials that cost around $6 per month (includes all your calling). Comparing this to a regular PSTN (landline) phone service that can cost in the region of $60 per month can result in savings of over $500 per year for many home phone users. If you also regularly call International numbers you can save even more, with rates typically starting from around 1 to 2 cents per minute to many countries.
Most of these VoIP solutions will require stable and consistent internet connectivity at every location where wired phones are to be used. At the very least, your business phone system must have access to a business class internet link to the cloud. This should be a dedicated link through a dedicated router if you expect your phone calls to sound as if they were coming from a business and not someone's home Skype connection. But it's important to know that you will also need a router that can create a virtual LAN (VLAN), and one that has the ability to encrypt voice traffic, and only your voice traffic. VoIP security from end to end for all calls is now a business necessity.

When shoppers ask which is the best VoIP service or who are the best VoIP providers, no two answers will ever be the same. Keep in mind, that the best service for one individual or business, might not be the most ideal for you. It’s all about finding a VoIP provider that can cater to your specific needs. Users should consider these factors when comparing VoIP providers:
VoIP endpoints usually have to wait for completion of transmission of previous packets before new data may be sent. Although it is possible to preempt (abort) a less important packet in mid-transmission, this is not commonly done, especially on high-speed links where transmission times are short even for maximum-sized packets.[18] An alternative to preemption on slower links, such as dialup and digital subscriber line (DSL), is to reduce the maximum transmission time by reducing the maximum transmission unit. But since every packet must contain protocol headers, this increases relative header overhead on every link traversed.[18]

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]
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.  
If you are seeking a superb pan/tilt/zoom (PTZ) video conferencing camera for medium-size meeting rooms, the Yealink VCC20 is an ideal choice. 2.18M pixels HD CMOS sensor plus 12X optical zoom power the VCC20 HD PTZ, delivering HD images up to 1080p at 30 fps. The Yealink VCC20 camera is an optimal solution for a smaller business environments. It is so detailed and true to life that you feel like you are in the meeting room with everyone else.
The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 gigabit per second) Local area network (LAN) using existing home wiring (power lines, phone lines and coaxial cables). G.hn provides QoS by means of Contention-Free Transmission Opportunities (CFTXOPs) which are allocated to flows (such as a VoIP call) which require QoS and which have negotiated a contract with the network controllers.
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.

You've probably been offered a home VoIP solution several times already if you've got cable TV service or if you're getting your Internet access from one of the larger Internet Service Providers (ISPs). Outfits like those love offering voice as the third leg of a "triple play" sales pitch: Internet, TV, and phone. When you see those offerings, what you'll be buying is a VoIP-based phone service, though generally one with slightly fewer features than you'll get from a dedicated VoIP provider because the provider generally isn't focused on their VoIP product, but one of the other two.


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).
Yealink DECT repeater RT30, designed in accordance with Digital Enhanced Cordless Telecommunication (DECT). The repeater can be deployed to extend the DECT radio coverage of Yealink W60B base station significantly in all directions, and when working with W60B, it supports two RT30 cascaded. Clear LED indicators are used to distinguish different DECT statuses. Its elegant design and easy installation are typically suitable to be used in the ambiance of all business environments.

Other basic features to consider include the phone itself should your provider offer its own handsets. Many residential providers don't since their bridge devices allow them to work with old-style landline phones, but some, especially the larger and more business-oriented players, do offer special VoIP phones. These look and work the same as a regular phone aside from the initial setup process, which will require making sure the phone is connected to your Internet router in some way and then configured to access the VoIP provider's service from there.
Vonage Business is the biggest name in VoIP, and the good news is it’s a leader in residential VoIP too. Vonage has powerful, nationwide infrastructure, ensuring 100% uptime whenever you make or receive a VoIP call through your home IP phone or the Vonage smartphone app. All pricing packages are billed monthly, with no contracts. However, if you agree to be billed annually, Vonage will reward you with close to a 50% discount on your first 6 months.

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]
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. 
VoIP solutions aimed at businesses have evolved into unified communications services that treat all communications—phone calls, faxes, voice mail, e-mail, web conferences, and more—as discrete units that can all be delivered via any means and to any handset, including cellphones. Two kinds of service providers are operating in this space: one set is focused on VoIP for medium to large enterprises, while another is targeting the small-to-medium business (SMB) market.[13]

(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.

E.164 is a global FGFnumbering standard for both the PSTN and PLMN. Most VoIP implementations support E.164 to allow calls to be routed to and from VoIP subscribers and the PSTN/PLMN.[27] VoIP implementations can also allow other identification techniques to be used. For example, Skype allows subscribers to choose "Skype names"[28] (usernames) whereas SIP implementations can use URIs[29] similar to email addresses. Often VoIP implementations employ methods of translating non-E.164 identifiers to E.164 numbers and vice versa, such as the Skype-In service provided by Skype[30] and the ENUM service in IMS and SIP.[31]

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.  

All 8×8 plans include team messaging, HD videoconferencing, and screen sharing, you you can easily keep all your at-home team members engaged and collaborative. And contact centers that have transitioned to remote work can still enjoy features like omnichannel routing, which allows your employees to engage with customers via chat, social media, text, and phone—all in one platform.
VoIP (pronounced “Voyp”) stands for “Voice over Internet Protocol” and to make a long story short—it allows you to make calls through your home internet connection. When you make a call with your VoIP system, your voice is converted into data and transmitted to the caller at the other end in the form of high-quality audio. The sound and connection typically are seamless enough to where you won’t even know the call you’ve received is from a VoIP line. 
He is the co-founder of NP Digital and Subscribers. The Wall Street Journal calls him a top influencer on the web, Forbes says he is one of the top 10 marketers, and Entrepreneur Magazine says he created one of the 100 most brilliant companies. Neil is a New York Times bestselling author and was recognized as a top 100 entrepreneur under the age of 30 by President Obama and a top 100 entrepreneur under the age of 35 by the United Nations.
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.
