It is a new technology based communication or way of talking over the phone just round the corner. The main advantage of this technology is that it minimizes the costs that come with a customary phone line, as a minimum at this point of the game. Additionally, this is new communication technology framework that offers the savings of hundreds, or yet thousands of dollars for a number of people. In addition, someone who has utilized voice chat software would be aware of the latency concerns that propagate through some kind of data transfer comprising the internet. However, VoIP technology addresses the latency concerns through RTP, or real time communication protocol. This communication protocol guarantees that data packets are sent and received in a timely way (Garden, 2011), (Swale, 2011) and (Karapantazis & Pavlidou, 2009). In addition, customary communication telephone network service providers are taking interest in presenting VoIP services also, with similar national businesses as AT&T and Verizon get high business revenue through the VoIP bandwagon. In this scenario, Vonage was one of the initial extensively recognized corporations to present VoIP communication based services, and is priced competitively by beginners to the marketplace (Garden, 2011), (Swale, 2011) and (Karapantazis & Pavlidou, 2009). This paper discusses some of the important aspects of VoIP. This paper will discuss technical areas and important features of VoIP technology based framework. This paper will also analyze the basic implications of VoIP technology and its possible evolution in future. TECHNOLOGY EVOLUTION The VoIP framework is based on the broadband technology and makes use of the World Wide Web (WWW) to route its communication calls. In this scenario, the most excellent thing is that the person who is being called through web phone needs not essentially have it as well to accept our call. So the technology that has brought modernism in our business and educational worlds as a minimum we need to look at its history (Rose India, 2009). Historically, this technology emerged in 1990 when internet phone was utilized using H.323 protocol in place of currently available common SIP protocol. Additionally, this communication software was extremely well known in the marketplace and through 1996. In this scenario Vocaltec had a success through IPO establishment. The place that SKYPE takes up in the marketplace was then occupied by Vocaltec. The weakness due to which this software got issues was the non-accessibility of high speed internet facility or broadband capability and a resulting reduced voice quality due to modems. The lower voice quality was inferior as compared to the usual phone calls (Rose India, 2009) and (Karapantazis & Pavlidou, 2009). In addition, the networking producers like that Cisco and Lucent soon became popular due to software applications that are able to route and switch the VoIP communication based packets traffic and consequently in the year 2000 VoIP technology based communication traffic accounted for 3 percent of the whole voice traffic in US. After that the year 2005 has seen all the important matters regarding VoIP traffic and thus clients are guaranteed of outstanding voice quality as well as continuous phone calls. Additionally, the benefit that was attained through this revolution that has been formulated out of sale of VoIP tools and equipment only in the year has been approximately $3 billion that reached up to $8.5 billion in 2008. The cause at the back of this amazing figure is small cost limitless calling plans and above all plenty of a variety of communication services and characteristics in telephone communication connected to VoIP technology (Rose India, 2009) and (Karapantazis & Pavlidou, 2009). Moreover, the need for video over this technology is increasing gradually and the speed through which this communication technology is going forward, its expansion is terribly thrilling. In this scenario, video phones have already been launched by a corporation named as Packet8. And it is marketing it by means of good-looking characteristics (Rose India, 2009) and (Karapantazis & Pavlidou, 2009). HOW VOIP TECHNOLOGY IS BETTER? There are a lot of reasons people prefer to choose VoIP technology for telephone service. However, the major reason is its less cost. VoIP communication technology has turned out to be well-known mostly for the reason that it is cost effective to the customers over customary telephone and communication networks. Additionally, VoIP reduces monthly phone bill by 50%. In addition, it also permits less costly worldwide or long distance calling rates that could be one-tenth of what is accused through customary phone businesses. On the other hand, its portability makes it an extremely high-quality option and one would like to keep away from costly hotel phone costs as well as cell phone roaming costs. However, it requires a high speed internet broadband link where one could be able to plug the communication set adapter into and people could contact them at their local number regardless of their location (ProgrammerWorld, 2009). Moreover, the majority of web sites charge a flat monthly communication fee arrangement from the customers. On the other hand, VoIP strategies do not charge per-minute charges for long distance calls. In addition, through VoIP calls using internet supported cell phones one could keep away from wireless roaming costs and long distance rates that normally touch north. However, the majority of the occasions in-network calls to additional VoIP service subscribers are free yet if the calling groups are situated in diverse areas of the world (ProgrammerWorld, 2009). MAJOR FEATURES OF VOIP The major benefit of VoIP is that it allows the users to make calls from anyplace in the world where a broadband internet link exists. In this scenario, people take their IP telephones or ATA's with them on nationwide as well as worldwide trips and yet are able to access what is fundamentally an individual's household phone line (Tech-FAQ, 2011). Additionally, most of the VoIP services come with call waiting, caller id, repeat dialing, call transfer and three-way dialing characteristics. However, for extra features or services like that forwarding a call, call filtering or transferring calls straight to the voice mail, the communication service provider can charge an extra fee. In addition, some of the VoIP facilities and services as well permit users to verify their voicemail on the web or attach messages to an e-mail that is transmitted to their PC or PDA. Normally, the services and parts offered by VoIP phone system service operators and suppliers can differ in different scenarios. Thus, people should evaluate the advantages and disadvantages before adopting these services. Furthermore, people should make sure that they have accessible technical support for the probable compatibility problems that could happen between the existing and new hardware components (Tech-FAQ, 2011). THE USES OF VIOP VOIP has turned into to be an evolving technique of communication in the contemporary world, particularly in sales-oriented professions. Additionally, most of the corporations are making use of this innovative technology to perform their business operations. However, its uses can be categorized into three main groups: (WhatIsMyIPAddress, 2011) For communication and to connect VOIP phones services inside single premises with the building's LAN (Local Area Network) To communicate and connect VOIP phones services between numerous locations of the similar business with a backbone communication network To communicate and connect VOIP communication phones to normal telephones in dissimilar associations or for sale purposes THE ECONOMICS OF VOIP VoIP communication technology has turned out to be well-known mostly due to its cost effectiveness as compared to customary telephone networks. In addition, the majority of Americans spend a flat monthly expenditures for local telephone calls and a for the per-minute costs of for long-distance phone calls. In this scenario, VoIP calls can be done all through the internet and all through the world. However, the most of the internet sites charge a flat monthly cost. Additionally, with internet connection both voice calls and data traffic allow the people to get rid of monthly bills of communication. In addition, VoIP plans do not force the customer to pay per minute for a call. Thus, people can save a lot of money by switching to VoIP technology (Tech-FAQ2, 2011). HOW DOES VOIP TECHNOLOGY WORK? The most common method of VoIP working is that the end user establishes a set up using high-speed broadband communication connection, a router and a VoIP communication gateway. Additionally, in place of a standard telephone communication link, here a router is used to transmit the telephone calls on a web based link. In this scenario, the VoIP communication gateway, located anywhere in closest location of the linked internet transforms the analog signals into digital format, those are more smashed into little chunks acknowledged as 'packets', previous to transmitting it over the internet. This process is similar to the way data is sent to and received from the computer. In this scenario, these data and information packets are transmitted to their last target as well as orders for carrying back into a comprehensible format are implanted in them. It then passes through a VoIP gateway, which decodes these data packets into the unique analog arrangement by making use of a Public Switched Telephone Network (PSTN), thus routing the illustrated to the number the caller has inserted for connecting. After that combining old school technology and hi-tech deliverance in a flawless as well as immediate method (Tech-FAQ, 2011) and (ProgrammerWorld, 2009). However, different types of VoIP tools and services are available to make communication simple and effective. In this scenario, the voice chat facilities offered by Google-Talk, MSN or Yahoo messenger could be considered as a VoIP. In addition, the extremely publicized communication through Skype; however these are proprietary arrangements. For instance, in order to communicate to somebody using MSN, an individual at the other end must also have MSN. The same condition also applies to the Yahoo as well as other communication tools as they make use of their own particular system for the communication and this system is not open as well as would not connect to other systems simply. In fact, VoIP should actually be based on SIP system that is a standard. In addition, SIP well-suited systems or devices can communicate with others even though people do not make use of PC. Additionally, some of the SIP telephones can make calls to the different sides over the web without requiring some extra equipment or even a phone supplier. People only have to plug their SIP phone into the web connection, organize it and then dial the further person right over the web (Tech-FAQ, 2011) and (ProgrammerWorld, 2009). However, in this communication process, our voice is transformed into data packets, similar to small files, and then sent to the receiver over the internet as well as re-interpreted back into our voice at the further end. In addition, to make this communication faster, these data and information packets are compressed previous to sending, a bit similar to zipping a data file (Tech-FAQ, 2011) and (ProgrammerWorld, 2009). DISADVANTAGES OF VOIP This section discusses some of the issues and problems associated with VoIP technology. In fact, VoIP technology is speedy, suitable and less costly. It has, though its own issues and problems. These problems are fundamentally because of the present dependence of on-hand systems on telephone based communication technology; and the inadequacy that plague computer communication technology (Cantor, 2008) and (ProgrammerWorld2, 2011). I have outlined below some of the major issues associated with this technology: Telephone Connections: In case of VoIP based technology services for instance security and cable yet depend on telephone links. Thus, unless the entire nation or world consents to move to VoIP, these communication services are probable to stick to their old techniques (Cantor, 2008) and (ProgrammerWorld2, 2011). This is not the major fear although: As VoIP depends on web based technology, it is as well vulnerable to the issues that engage in the internet and computers. Thus, in this scenario, people can expect similar issues such as crashes, viral attacks and stolen packets (Cantor, 2008) and (ProgrammerWorld2, 2011). At the present we are familiar with the fundamental answer to how does VoIP work. Actually, this portion of technology does grasp numerous potentials. Similar to everything else, the old methods of communication above long distances have to be modified. In this scenario, VoIP communication services could be initial logical move that can be taken. However, it can take a long time, previous to VoIP turns into a completely integrated and snag free system (Cantor, 2008) and (ProgrammerWorld2, 2011). Emergency calls: Another important issue with VOIP is regarding emergency calls. Customary phone equipment can be used to trace caller’s location. In this scenario, the emergency calls are changed to the adjacent call center where the communication operators are able to observe caller’s place in conditions caller is not able to talk. Though, for the reason that a voice-over-IP call is fundamentally a move of data among two IP addresses, not communication based physical addresses, with VoIP there is at present no method to decide where the phone call is initiated (Cantor, 2008) and (ProgrammerWorld2, 2011). Thus, it is very difficult to access the location of caller. No communication service during a power outage: In the course of the total blackout a usual phone is kept in service through the present supplied all through the phone line. However, this is not possible in case of IP phones, consequently when the electric power goes, there is no way that people could use VOIP phone service (Cantor, 2008) and (ProgrammerWorld2, 2011). FUTURE OF VOIP Mobility is a main competitive benefit for today's small corporate workforce. As most of the people work-at-home and tele-working workers augments, in this situation wireless VoIP could be a very useful future trend and necessity. The main advantage of wireless VoIP for small companies is offering staff one phone number where they could be accessed no matter where they are sitting (Kopf, 2011) and (Hallock, 2004). It would also be very useful for individuals, who want to communicate with their friends and colleagues at the lowest price.
