VoIP 101 or How VoIP Works

Get ready to change the way you think about long distance phone calls. VoIP, or Voice over Internet Protocol has arrived. VoIP is a method for taking analog audio signals ( like the kind you hear when you talk on the phone ) and turning them into digital data that can be transmitted over the Internet.

The technology has already been around for a while and is growing steadily. Major carriers like Telus, Bell Canada & US companies like AT&T are already using VoIP to facilitate long distance calls.

Above all else, VoIP is basically a clever "reinvention of the wheel." The principles behind VoIP, its applications and the potential it has will more than likely replace the traditional phone system entirely. This will brings major changes to everyone’s lives offering more options for phone service at cheaper rates.

How current analog telephone systems work.

To understand how VoIP works you’ll need to understand the basic concept behind regular analog audio communication as well, since this is the precursor for VoIP. Analog phone calls are actually made via fiber optic networks by digitizing your voice communications for sending the signal across thousands of miles, but once it gets to the final destination (a home or office phone for instance) the signal is once again converted to analog.

During these calls the switches remain open even while there is dead air and no conversation is taking place. The circuit is also open in both directions even when only one party is talking and the other is listening. This method isn’t very efficient and slows down the communication of information considerably.

Switched Packet technology, the power behind VoIP.

VoIP works on a different premise -- rather than circuit switching, data packet switching sends and receives information only when you need it instead of in a constant stream. It also sends the information packets along whatever open channels are available rather than a dedicated line which is much more efficient. The information is simply reassembled at the destination.

The use of multiple routes in order to send digital information makes packet switching quicker, much less expensive and more efficient. The savings in long distance charges can be in the hundreds or even thousands of dollars per year.

Use your existing telephone with the Dolphin Adapter.

Dolphin Global Tel offers a VoIP product that uses Analog Telephone Adaptors (ATA's) which we call the Dolphin Adapter. This adaptor enables you to connect a standard telephone to your highspeed Internet connection in order to take advantage of VoIP options. The ATA converts analog signals to digital so that it can be transmitted properly via the Internet. This is a simple small preconfigured device that takes only a few moments and little or no computer skills to connect and start making calls.

The upshot of Dolphin Global Tel’s VoIP packages is that standard long distance charges have become a thing of the past. As more and more consumers connect with Dolphin Global Tel’s VoIP service by using their broadband connections, they will find it easy and inexpensive (as well as practical) to make phone calls over the Internet.
