When converting from traditional telephone service to VoIP, many people choose to use their old analog phones and convert the signal using an adaptor or router. This may not, however, be possible for all service providers. For state-of-the art installations or installations where VoIP phone hardware is required, the choice is to upgrade your handsets to VoIP phones. These special VoIP phones may look just like a traditional telephone handsets but instead of having the standard RJ-11 phone connection you are accustomed to, they will have an Ethernet connector (RJ-45). VoIP phones connect directly to your network, probably through your router. True VoIP phones have all the hardware and software you need to take advantage of all the features VoIP telephony.
VoIP phone communication requires a broadband (high speed Internet) connection which you can access through a cable modem or other high speed service. This service will be purchased from a third party provider. If you want to access VoIP phone services using your traditional hand sets, you will need your computer, a router or ATA adaptor. If you have a true VoIP phone, your connection will be directly through your broadband connection and you will dial just as you normally would. You can also access VoIP phone service directly through your computer. This will require software and a headset/microphone. USB VoIP phone sets are also available and very convenient.
There are different types of VoIP phones. An Ethernet hard VoIP phone will look to the naked eye much like a traditional handset. Its connection is through an Ethernet port and it will communicate directly through your VoIP connection. It does not require a computer and it operates essentially the same way that your old landline did. In many cases you will actually have a dial tone.
One of the more popular VoIP phone options is a cordless phone with base station. These convenient VoIP phones contain the Internet interface in the base station. Another less prevalent type of VoIP phone is a dialup hard phone with a built-in modem. We don’t see this type of phone too often in North America, but there are places in the world where this type of phone is necessary due to limited access to broadband connections. These phones connect to a VoIP server via a dial-up Internet connection.
Another VoIP phone option to consider is a WiFi phone. A WiFi VoIP phone generally has a built in transmitter which connects to a WiFi base station. From the base station the signal is transmitted to a remote VoIP server. WiFi VoIP phones do not require a computer.
As you research your options for VoIP phones you may see references to hard phones and soft phones. We have discussed several hard phone options above. These are actual handsets that work with VoIP technology. When we receive our telephone service through your computer using software and a headset/microphone it is referred to as a soft phone. A key advantage of soft phones is that they can be considerably cheaper than hard phones. In fact, there are many soft phone options that are available for very little cost or free.
Voice over Internet Protocol (VoIP) allows you to make basic communications functions, such as voice calls, voice messaging and facsimile over the internet instead of the traditional telephone network.
You can use your existing broadband internet connection so there is no need for a second line to be installed. You simply sign up to a VoIP service provider who will charge you a subscription charge, and/or your call charges. When you sign up to a VoIP provider you are given a VoIP number which is the same as a traditional phone number, and what you give to other people so that they can contact you.
VoIP Costs
With VoIP you can still call any number that you want whether it be another VoIP user, a landline or a mobile. You are not limited to other VoIP service users only. The charges for all calls depends on the VoIP service provider that you sign up with. You may find that some calls using VoIP are cheaper than a traditional telephone network, whilst others may work out more expensive. Depending on your VoIP service provider you may also get a number of free calls, particularly to other VoIP users with the same provider.
The cost of VoIP varies depending on which VoIP service provider you use. Some will charge a monthly subscription fee which may include a number of calls, whilst others may simply charge only for the calls you make. You may also have to pay an one-off set-up fee or for any equipment you need to use VoIP.
Many VoIP service providers offer a pay-as-you-talk option similar to that which is offered with mobile phones. You simply purchase credit from your VoIP service provider and make calls until that credit runs out, before purchasing more credit to use again. Some VoIP service providers may require you to top up your account by a minimum amount for a fixed period.
VoIP Technical Issues
VoIP uses broadband connection so your use of it will be as reliable as your existing broadband internet connection. Therefore, if your connection often drops then you may find it will do the same with your VoIP usage. Broadband technology is relatively dependable but you may suffer problems if your internet service provider has technical issues or there is a high amount of internet traffic.
If you use VoIP via your computer then it will have to be turned on in order for you to make or receive calls. To put it simply, if your computer is not on then people will not be able to contact you on your VoIP number. Some VoIP service providers may offer a voicemail option in order to pick up messages from any calls you can not take but you may be charged for this service.
It should also be noted that some VoIP service providers do not allow you to make emergency calls so you should also ensure that you have another way of getting hold of the emergency services if required.
VoIP, voice over Internet protocol, is most commonly called Internet phone service. VoIP services allow you to use your broadband Internet connection to make and receive telephone calls. This technology is fast becoming the standard means of communication for many people and with good reason – VoIP services are fast, reliable and typically much less expensive than a standard voice land line.

Moreover, it is very functional as many call centers and networks come to your aid. Then there are other advantages such as three way calling, call waiting, caller ID and call forwarding. These facilities are not available on a traditional landline.
The emerging IEEE 802.16 standard, commonly known as WiMAX, promises to deliver last mile wireless broadband internet access capable of carrying data intensive applications, such as VoIP and streaming video, to Metropolitan Area Networks, as well as sub-urban and rural communities. WiMAX is considered a disruptive technology, designed as an alternative to fixed line DSL and coaxial technologies, and with its 802.16e revision, the cell phone networks as well.
Worldwide Interoperability for Microwave AXcess will operate over licensed and non licensed frequencies using non line of sight (NLOS) and line of sight technologies, extending broadband coverage to cities and towns wirelessly via a metro area network. Additionaly, because of its far reaching capabilities and ease of implementation, wimax is the one technology likey to bridge the Digital Divide, connecting underdeveloped regions and sparsely populated rural areas much more cost effectively than deploying a wireline infrastructure.
WiMAX and WiFi Compared
The widespread adoption of the wireless LAN in the business community, as well as the emergence of WiFi hotspots in public areas, airports, hotels and cafes, has been of tremendous significance in providing mobility to business people and consumers alike. Thanks to the open standards guided by the 802.11 committee and the WiFi Alliance, WiFi technology is becoming ingrained in our society. WiMAX plans to take WiFi a step further.
While the two technologies may sound the same, they are from their conception designed for totally different applications. WiFi is a short range standard that was designed primarily as an extension of the local area network (LAN) to provide mobility for the end user. It operates over unlicensed frequencies and has a range of about 100 meters, depending on obstructions. Typically one access point will be connected to a fixed line network, either a wired LAN or a DSL/cable broadband connection, and the range can be extended by adding more access points at appropriate distances.
WiMAX, on the other hand, is designed to function as a carrier network, or a wireless Internet service provider (WISP), blanketing whole cities and regions with broadband Internet access comparable to DSL. Coverage in optimal conditions could reach 50 kilometers, but in reality are more like 5 km for users with NLOS customer premise equipment (CPE), or up to 15 km with a CPE connected to an external line of sight antenna.
As the older more established technology, the 802.11 WiFi has been used in a mesh topology to cover larger areas such as college campuses and municipalities, for example to connect the terminals in police vehicles to their database. The emerging 802.16 WiMAX will be better suited for larger deployments, and will in fact compliment the private WiFi networks by offering a cheaper and more secure Internet access for data and voice applications.
The WiMAX Standards: Fixed, Nomadic, and Mobile
The 802.16 standard developed by the IEEE envisions a fixed wireless broadband network operating in the spectrum range of 10 GHz to 66 GHz. Originally, only the licensed spectrum was addressed in this range, and line-of-sight multipath technology was dealt with by adopting OFDM as the standard. Subsequent revisions added the 2 GHz to 11 GHz band to the spectrum, and incorporated support for non-line-of-sight technologies and Quality of Service (QoS) techniques, a prerequisite for such time sensitive applications as voice and video.
The revision known as 802.16-2004(d) rolled up all the previous revisions and then added some. Most of these original issues dealt with the Physical and Media Access Control layers, and resulted in a standards list of optional and mandatory elements by which vendors could design their products.
The resulting fixed WiMAX standard has a data rate of up to 40 Mbps, support for half and full duplex transmission, improved QoS, and the incorporation of multiple polling techniques, ultimately reducing packet collisions and overhead.
Base stations are to support several different topologies, such as wireline backhauling, microwave point to point connections, and the ability for the WiMAX base station to backhaul itself by reserving a part of the bandwidth for that purpose.
By design, 802.16d would cater to the residential and small business markets offering wireless broadband access with speeds comparable to DSL. Enterprise markets could be served at T1/E1 data rates.
While this version of WiMax is called fixed, it is in all actuality nomadic. Users on a private WiFi network indoors could be passed off seamlessly to the publicWiMAX network when moving outdoors, their hardware determining the best network available. Devices on the WiMAX data network would include laptops, PDAs, and smart phones equipped with an on board WiMAX capable chip or PC card, utilizing the spectrum for voice, data, video, and music transfers.
Nomadic WiMAX provides for limited mobility in that the range of coverage is handled by the same base station.
WiMAX Goes Mobile
With the adoption of the 802.16e revision in late 2005, all the hype has been on Mobile WiMAX, a technology designed to compete with the cellular networks.
With major support from manufacturers like Intel, Motorola, Siemens, and Nokia among others, mobile WiMAX is built on open standards and is purported to be 4 times faster than the cellular 3G technologies (EVDO, HSDPA). Significant cost savings can be achieved for voice applications by placing calls over the Internet through VoIP.
802.16e provides for fast and seamless handoffs between base stations, with a cell radius of about 3 miles, similar to cellular networks. The standard was ratified in late 2005, and real world applications are beginning to show up in 2007, with more robust development expected throughout 2008.
Because this technology is such a threat to the legacy telecommunications industry, it is no surprise that Sprint Nextel will be deploying WiMAX as opposed to EVDO in its 4G network. Sprint has been buying up much of the WiMAX spectrum, and has recently announced a partnership with Nokia to deploy WiMAX to four Texas cities by mid 2008. This is not their first WiMAX network, and telcos around the globe have been doing the same.
The 802.16 standards are a work in progress, and as such, are subject to changes and revisions. As the standards committee works on the technology, the WiMAX Forum hopes to do what the WiFi Alliance did for the 802.11 standards, by promoting interoperability between components through testing, and offering WiMAX certification to vendors that conform to the 802.16 standards.
It should be noted that many of the WiMAX implementations at the time of this writing are proprietary, and thus do not necessarily follow the recommendations of the IEEE or the WiMAX Forum. The broadband wireless ISP Clearwire Communications has over 200,000 subscribers in 375 cites, and calls its service a WiMAX-class solution, utilizing next-generation, non-line-of-sight wireless technology. Other early adopters of pre-WiMAX technology are forging ahead, providing wireless broadband access to residential consumers and the small business market, with many companies climbing aboard the evolving standards bandwagon to assure interoperability and backwards compatibility of devices and applications.
VoIP (Voice over Internet Protocol) is fast becoming a preferred method of communication in the home. It allows broadband users to make telephone calls over the internet.
The attraction of VoIP is not hard to fathom: it offers the potential to make ultra-cheap or even free calls anywhere in the world, to use local telephone number codes even if you are not physically based in that location and even to take or make calls without the need to keep your computer switched on.
So how does it work? Basically, VoIP converts voice signals from your telephone into a digital signal that travels over the internet, then converts it back at the other end, therefore allowing you to speak to anyone with a regular phone number, as well as other broadband users.
VoIP is still at its developmental stage, but the number of VoIP providers is increasing, giving you more choice and better calling plans. VoIP services are available for both commercial and residential users, ranging from services that operate PC-to-PC through to a handset plugged into your router-to-phone. Many broadband providers now offer a VoIP service in their bundled deals.
As long as you have broadband VoIP can be used in several ways, from using software on your computer to integrate with your microphone, to VoIP phones that look like regular phones.
Due to calls being made over a broadband connection, VoIP calls are significantly cheaper than your regular phone calls, especially international calls. The other advantage of VoIP calls is that as long as there is an internet connection you can make phone calls. Even if you’re getting your broadband via mobile broadband without plugging into a wall socket you can still make calls.
The major disadvantage of VoIP is call quality; many users with slow broadband connections suffer from a variety of problems that makes it hard to hear what someone is saying. Another major disadvantage is that a VoIP line can never be a true replacement for a normal phone line because it’s not possible to call emergency services, and if you try to make calls to countries that have an analogue phone service it won’t work.
However, with broadband technology improving and millions being invested in wireless technology and networking, even mobile phones are vastly improving their internet capabilities and some manufacturers looking at allowing VoIP calls straight from your mobile perhaps one day we won’t need our phone lines anymore.
If you are interested in taking advantage of current broadband internet technology then you should compare many cheap broadband providers available in your area.
Did you know that you don’t have pay outrageous phone bills anymore? In actuality, you can abandon your phone company altogether while still enjoying all the normal telephone services you want with one low-monthly charge. It’s called VoIP (Voice Over Internet Protocol) and Comcast Cable has it. Comcast Cable VoIP is emerging in 2007 because so many customers have acquired a aversion for the phone companies and would like a viable alternative to paying per-minute fees. By utilizing your broadband internet connection you can have LIMITLESS domestic calling – no more long-distance charges! Comcast Cable VoIP is prepared for prime time and you can finally keep big money by eliminating per-minute phone bills.
Comcast VoIP is the Future of Telecom
VoIP is everywhere because it operates by transmitting voice over the Internet. VoIP actually isn’t a new technology. VoIP telephone service made its broadcast unveiling in 1995. But only lately have cable companies been able to take the technology to residential homes. VoIP works as good as your cable connection and allows users to tap into the complete capacity of the Internet. VOIP services are effective because you don’t have to buy any new gear. Comcast technicians transparently plug your existing telephone system into a cable broadband modem. The only thing you have to do is enjoy cheaper monthly bills. Comcast VoIP is both the most reliable and best value for the money among all the existing cable companies offering telephone services.
How Comcast Saves You Even More Money – Three Great Services and One Low Bill
But Comcast doesn’t just offer phone service. You can save even more money by bundling digital cable TV, broadband internet, and VoIP into one monthly charge. Bundled services from Comcast Cable TV are plainly a winning idea for customers. With Comcast bundled services, you can choose digital cable, home telephone service and high speed broadband Internet together. The advantage of having Comcast bundled services is that it is greatly easier to keep track of your utility expenses when the bundled services are charged on one monthly amount. It is cheaper to buy multiple services through Comcast than it is to buy one service from several providers. While it’s true that these bundled services will save money over subscribing to the same services through different companies, not all bundled packages are the same. The bundled services provided by Comcast are among the best for a number of reasons. Comcast’s bundled services are better than other bundles you can get through other companies because many companies have the tendency to outsource some of their services. Comcast offers and maintains they’re own products and give legendary reliability to customers. Don’t make the error of using poor, unreliable third-party providers.

Solution Voip, to day from residential users to big corporate offices use to cut off their telephone bills. With emergence of VoIP phone service, long distance or international calls have become cheaper, especially when we use for peer to peer. The calling services through the Internet connection work out much cheaper than traditional PSTN phone line connections. The advanced feature of telecommunication allows users to make local calls, long distance or international calls at cheaper rates.
VoIP, sometimes called Internet Telephony, IP telephony, or Internet phone, uses your computer’s broadband connection – not traditional phones lines – to make long distance, inter-state or local calls. VoIP works by converting your voice into data, transmitting it over the Internet, and then converting it back into a voice stream so that it can be played on any telephone in the world – almost in the same way your computer transmits email over the Internet.
The most attractive thing in getting these values added services from them is that they are free of cost. These broadband phone service providers also provide a service of virtual phone number. The use of this virtual phone number is that it possesses an area code from where you generally receive the maximum number of calls, and the rates will be very cheap for the people who are calling you.
The most significant factor that affects the functioning of the VOIP phones is the Broadband Internet Connection, which is a high-speed internet connection and will be used for making and receiving phone calls. As there is a use of broadband internet connection in VOIP phones, they are also known as, “Broadband phones.”
Bandwidth Required For VOIP Phones
The functioning of VOIP phones depend upon broadband internet connection and the quantity of data transfer by broadband internet connection is directly proportional to the bandwidth speed. In other words, bandwidth is the capability to transfer data in a given span of time.
There are two different types of bandwidth. One is the upload bandwidth, which is the quantity of data sent to the internet, and the other is download bandwidth, which is the quantity of data received from the internet.
It is always recommended to use the broadband bandwidth of 90 Kbps as VOIP telephone calls utilize 90 Kbps of bandwidth for high sound quality. But if broadband net service provider is unable to provide this much of bandwidth then most of the VOIP service providers provide an option of lowering down the voice quality by lowering down the bandwidth to approximately 60 Kbps or 30 Kbps.
Voice over Internet Protocol or VoIP has broadened up the perspective of Internet and traditional communication services. Businesses, large or small, are one of potential users who are availing benefits of the efficiencies associated with IP based communication and services. But services are not the same for everyone! VoIP services depend upon the size, operation and requirement of the business and corporate houses including the residential users.
VoIP is a technology one that allows the users to make voice calls using a broadband Internet connection instead of a regular phone line. The VoIP phone service enable the users to send data, images, voice and video over the single IP network. Therefore, it can be said that user enjoys visual and verbal communication together in a more effective way. This increases the cost efficiency and call productivity of voice over IP services. While using the IP services, the user enjoys calling over longer distance or international calls at significantly lower rates compared to Public Switched Telephone Network or PSTN.
There are many advantages of using Voice over IP services like:
1.It lowers Phone Bills up to 50%
2.Offers mobility i.e. you can carry phone line along with you
3.Reduces longer distance or international bills
4.Extenuate surcharges
5.Many providers, avoids monopoly
There are many VoIP service providers in the market. Some may provide their services onto the same telephone service, while others offer their services on the other telephone lines or numbers – including local, long distance, mobile and international numbers. Moreover, while selecting the best service provider, the potential user must check the hardware essentials. To bring into notice, some VoIP services work over computer or a special IP phone whereas other services allow you to use a traditional phone connected to an adopter. Lastly, branded VoIP ineternet phone service providers offer a lot of features along with their services like three way calling, call waiting, caller ID and call forwarding.
Keeping in touch with friends and family can be a frustrating and costly business – especially if they live abroad. Letters are notorious for going astray and, if you need to speak to someone to deliver important news, international phone call charges can seem a little extortionate, especially in the current economic climate, making regular contact perhaps not as regular as we’d like it to be. The dawn of email and broadband has made the world a little smaller and certainly less expensive, but there are some occasions for which only the sound of a voice will do.
Thanks to broadband technology, VoIP phone calls are becoming more and more commonplace. This technology utilises your existing high speed Internet connection to send and receive telephone calls at a much less expensive rate that traditional telephones. Cheap international calls or even free international calls are now a reality, thanks to VoIP. Free international calls do offer some restrictions but, if you’re prepared to sign up with a VoIP service provider for cheap international calls, you gain flexibility alongside some low cost options.
In order to make free international calls, the cheapest option is to use the ‘PC to PC’ method. As its name suggests, phone users use their computers as telephones to speak to each other, using headsets, microphones and speakers. While this does mean you don’t have to pay for the call, it also means that you do not have the freedom of a telephone: you are tied to the computer and the other party must be using the same or a compatible system to receive the call. This method does not allow you to make free calls to mobile phones and landlines; you will be charged for these by the minute. In addition, the sound quality is not as good as traditional phones and the signals involved can often break up and disconnect the call.
Using a ‘landline to landline’ VoIP provider gives you the flexibility of a traditional phone, but offers you cheap local and cheap international calls. Using an adapter sent to you by your provider, which your telephone and broadband modem or router plugs into, you can then begin to make and receive phone calls. The beauty of this lies in the fact that, unlike the PC to PC method, the other party does not have to have a computer and your regular digital telephone will work, regardless of whether your computer is switched on or not – its connection to your modem allows it to access the correct bandwidth at any time. In addition, you don’t have to worry about calls breaking up and the sound quality is indistinguishable from that of traditional call. Using a VoIP provider to benefit from cheap international calls, you pay only a monthly subscription fee for the countries you want to call, so you’ll know in advance exactly what the cost is.
As telephone companies continue to increase the costs of international calls, it is small wonder that many consumers are changing their providers and either signing up with VoIP providers or using their personal computers to make free international calls.
