How VOIP Call works

How VoIP Works..this is the first question that will come to your mind if you are new to VoIP technology. I will provide the simplest answer to this question here in this blog.

Calling party picks up the receiver of the phone. The phone sends an electrical signal to the analog telephone adapter, ATA. If the internet connection is up, ATA will send a dial tone to let the calling party know that they can make a call. Then the destination point phone number is dialed. The phone number data is sent in the form of a request to VoIP service provider’s call processor. The phone number is converted into an internet protocol hexadecimal address. Using this IP address, a signal in the form of a packet is sent to the called party’s which make the bell ring. When called party picks up the receiver a session is established. During the conversation, your computer and your friend's computer transmit IP packets back and forth. The ATA converts these IP Packets to the digital signal and then to analog voice signal recognizable by humans.

So do you have any about your daily or monthly calling volume and how many bucks you can save through voice over IP phone.

Recently Google has started its own VoIP messaging service called Google talk. In this you just need to download the software available for free on internet and a broadband internet connection. Just plug in speakers and microphone and you are ready for conversation. Yahoo messenger, AOL, Skype also use Instant Messaging services that have voice options enabled. These VoIP phone systems are perfect for small businesses or for use in the home office.
