VOIP – Talk Easy, Without Worry About Money

March 29th, 2010



Those were still the early days of the entry of VOIP in the market. Still an esoteric term to many of us. Not so much today. Once feared and revered as an elite technology that only the experts could make head or tail of, it has of today, become an organic mass system of means of communication. It would not be an overstatement to say that VOIP is leading the way in digital communication.

To cut through the rhetoric, what we know is that VOIP refers to Voice over Internet Protocol. This technology converts spoken sounds into digital signals. This allows the voice to be transmitted over a network such as the internet. Your voice is transmitted as sound data packets across the internet to the receiver at the other end. The internet should be broadband or high speed connection. Apart from this, you will require a cable modem or other means of wireless services, a phone equipped with this facility or a special software inside it for this purpose.

There are also a few minor problems with these services such as failure to function during a power outage, especially as when your service provider may not offer backup power for these situations.

VOIP technology has revolutionised the way calls are being made and billed around the world.
It has made talking to anyone around the world as easy as surfing the internet. and this means of telephony often costs you nothing more than than the rate of a local phone call.

Certain things to be kept in mind while using this service: Your service provider may charge you for calls outside your area, so make sure to check the terms of service for the same. You may also avail these services at flat rates as offered by some providers to be able to make long-distance calls at the lowest rates you would have ever imagined. These services may be availed with either your traditional handset phone or with a microphone over the Internet.

Accessibility at economic rates is no more an issue with VOIP.

VOIP Broadband Phones – What Should You Know?

December 24th, 2009



The expanded form of VOIP is Voice Over Internet Protocol. 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.”

Principle Of VOIP Technology

The main principle of VOIP technology is to transform the voice into digital signals which will be forwarded to the broadband internet. This net connection will then help in the conversion of the digital signals into voice before reaching to the listener.

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.

Uses Of VOIP Broadband Phone

The broadband phone can be utilized to replace the analog phone line or it can be used as a second phone. The most significant use of VOIP service is to make long distance and internationals calls at very cheap rates.

This feature has proved to be very much attractive for the people and companies that are into businesses at international levels. There are different types of value added services that are offered by VOIP broadband phones like caller ID, call diverting, 3-way calling, call waiting, etc.

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.

Precautions While Using Broadband Phone Services:

Though the use of broadband phone service is very advantageous, you should always consider the below-mentioned precautions while utilizing the broadband phone services.

1 – As it is very clear that broadband phones work by the transmission of digital signals by using broadband internet connection, it is always suggested to go for a high quality broadband connection else it will affect the quality of the phone calls.

2 – You should always be ready with a back up in case of break down of power supply and internet connection as this break down will stop the functioning of broadband phones.

3 – It is the responsibility of the users to update the VOIP service providers regarding your current address so that they can assist you at the time of emergency through their service of 9-1-1.

It is always recommended to search for the functioning of technology, benefits, and limitations of the VOIP phones while planning to have a broadband phone connection so that your investment should not go into drains.
