Disadvantages and Advantages of VOIP

March 15th, 2010



VOIP (voice over internet protocol) has been making a lot of noise in the market today. It is getting its share of popularity and some say that VOIP may even replace traditional phone services in the future. Like any other form of technology, it is valuable to know the present advantages disadvantages of VOIP.

One of the advantages of VOIP use is its low cost. One who owns a computer and has fast internet connection can make unlimited PC-to-PC calls to anybody anywhere in the world, most for a cheap price and some for free. They are usually very helpful when making overseas calls as such calls can be quite pricey if you use traditional phone lines.

Another advantage of VOIP is that it is portable, as the connection isn’t limited to the conventional baseband links. Wi-Fi hotspots have increasingly increased nowadays and they enable portable computers to receive and make calls. With that, a person then just needs to sign-in to his/her VOIP account. This is very efficient if one wants to connect with business partners or a family member while traveling.

There are however, a few disadvantages to using voice over internet protocol at the moment, though they are being addressed. One is that VOIP services, unlike regular phone lines, go down when there is no hint of electricity. So when blackouts occur, VOIP is offline as well. Backup batteries can help, but only for a limited time. Another concern is that most VOIP services cannot be used for emergency calls because internet phones do not have locations. Traditional phones are available on these occasions, as locations for each telephone are fixed, and they do great help when they are needed the most.

Advantages and Disadvantages of VoIP

February 22nd, 2010



VoIP technology has resulted in serious changes in the way we communicate with each other. It has succeeded in integrating both voice and data and utilizing the Internet for communication as well. Telecommunication is continually evolving and as people we can only continue to benefit from this evolution. Internet based phones will be the telephony service of the future but are its advantages being overemphasized? All things may not be as they seem.

VoIP has a great number of benefits and advantages. The only requirement that VoIP has is that you use a broadband DSL or cable connection. Provided you have this sort of connection, you can easily use Voice over IP. If you use yours through a PC-to-PC connection calls are usually free just as long as the person you are calling has VoIP as well, other than this most VoIP providers tend to offer unlimited calling plans for calls made outside a certain geographical area for a flat monthly fee. Traditional telephone services are much costlier than internet phones. This technology also offers additional services such as call forwarding and caller id, free of charge.

One other benefit of the integration of voice and data is that the person needs only a single system. It makes it easy to install and save money as well. Each phone is identified by a single IP address regardless of wherever it is plugged into. This makes it easy to move from one place to another or to add it to other networks as well.

These VoIP phones may also be utilized anywhere just as long as they have been connected to an IP network. This assists a lot with telecommuting and international offices as well, saving companies and individuals a lot of money. These devices also tend to be light and very easy to carry.

Regardless of these numerous benefits, there are disadvantages. The biggest disadvantage would be that VoIP is run by a lot of power. If a power outage occurs all voice communications cease, unlike the traditional telephone service which can still be made use of if there is no electricity.

Problems also exist with the calling of 911 emergency numbers. When you usually make a 911 call it is traced back to the sender and sent to the nearest 911 communication center in the area. However with VoIP these calls cannot be traced back to a particular location and cannot lead rescuers to find you.

Voice quality with internet telephony is generally efficient but the use of cable broadband could mean poorer qualities. This is because the data is broken down in order to be transmitted and the delay or a packet of data will sometimes mean that it needs to be dropped. This then results in silent periods.

Phone equipment may also need to be updated since voice over IP only tends to work with newer phone versions. Depending on the number of phones that need to be replaced, this could a substantial expense.

VoIP also has some minor annoyances that have to be sorted out but the benefits far outweigh the disadvantages. From all evident aspects this alternative telephone technology is the phone of the future but the future may already have arrived for all we know.

VOIP Technology – the Next Step in Phone Industry

November 11th, 2009



Most likely, voip will replace telephone service in the near future. VOIP is becoming very reliable and thus, receiving acceptance. Phone companies are already taking advantage of the technology to provide inexpensive long distance rates.

Voip generally has low costs, which is one big indicator of its growing popularity. You can sign up with a voip service provider for a monthly fee and get unlimited calls within a specified geographic area. There are some voip services in the United States that allow connections for no extra charge.

There is another benefit of having voip as opposed to a regular form, and this comes in the form of portability. You can make and receive phone calls wherever there is a broadband connection by simply signing in to your voip account.

When you are traveling, you simply pack a headset or Internet phone. Internet phones are small and light enough to take anywhere. When you sign up with a voip service provider, the Internet phone or adaptor used by that service is assigned a unique number. This ‘phone number’ remains valid, even if your voip service is in San Diego and you are connected to the Internet in Spain. When plugged into a broadband connection, anywhere in the world, you can make and receive calls as though you were at home.

Call forwarding, call waiting, voicemail, caller ID and 3way-calling, are included with Internet telephone at no extra charge. While you are talking on the phone, you can send pictures and documents at the same time.

Although there are many attributes to a voip phone, there are also some things to consider that could fall on the negative spectrum. For one, services are not useful in emergencies. Traditional phone equipment can trace the locations of calls. Emergency calls are diverted to the nearest call center where the operator can identify your location, in the event you can’t talk. With voip, there is no way currently to determine where Internet calls are originating.

Standard phone service continues by the current supplied through the phone line during a blackout. This isn’t possible with Internet phones. When the power goes, there goes voip service. Battery backups and power generators that provide electricity are solutions to the problem.

In addition, you should keep in mind that voip has sound quality and reliability problems. Data sent across the Internet usually arrives at its destination scrambled. E-mail and documents can be reassembled in the correct order when it arrives. Voice data also arrives scrambled, but it’s more complicated because of the real-time nature of VOIP. Some data packets may have to be dropped when they don’t arrive in time, in order to make voice connections with the least delay. Distance and speed of the connection determine the amount of data lost. Some networks receive more traffic and thus are more likely to cause audio dropouts.
