VOIP technology – Some Arguments

Voice over Internet Protocols (VOIP) is a widely popular Internet telephony system. Lot of companies have been using this technology to offer cheap services, especially for ISD calls. Most of the leading service providers use open systems. Apart from this open system some providers use DSL services.

Top providers of VOIP are listed as:

  • BroadVoice
  • EarthLink
  • Lingo
  • Vonage
  • VoxFlow
  • AOL

Arguments in favour of VOIP

VOIP has recently introduced an enhancement in its technology. It is nothing but Analogue Telephone Adapters (ATA). These adapters are essential for the conversion of VOIP signal when you use it as a normal telephone. These adapters are marketed in 2 distinct forms. One type of adapters performs with the connectivity of high speed USB ports. Here your PC has to be switched on when you make a call. Therefore it is possible to plug into your PC with USB port. Another type of adapter functions with the support of DSL modem or cable.

  • Cost advantage

Cost advantage is a widely popular benefit of VOIP phones. The cost of making a call to a distance place is very cheap when compared to normal telephone call rates. The only requirement to enjoy this benefit is the high speed Internet access. With this feature you can make calls all around the world. If you get a virtual phone number for making calls within an area, you can make calls by subsidized rates.

  • Portability

Portability is a vital advantage of this VOIP technology. It is very simple to use this technology wherever you are for which you have to have an Internet access.

Arguments against VOIP

Even though, there are several advantages, this digital technology has been criticized on certain grounds. Some of the common criticisms of this VOIP technology are listed as:

  1. Lack of continuous service: There is no guarantee that you can enjoy this technology continuously due to the power fluctuations or slow access of Internet etc. It is possible to use the traditional telephone lines though there is no power supply. In case of VOIP, power supply is essential. Without power you can’t do anything.
  2. When you make an emergency call through traditional call, the call origin can be determined easily like the phone number, address etc. But if you make an emergency call through VOIP, it is impossible to find out the origin properly.
  3. You may not the quality of sound and reliability as traditional phones.
