1. What is VoIP?
VOIP stands for Voice over Internet Protocol. It is a technology that allows voice data to be transmitted across the Internet using a system called Internet Protocol. Fundamentally, VoIP uses packet switching instead of switches to send data from one person to another. However, special equipment is needed at both the receiver’s and sender’s end to complete the process.

2. Why use IP for voice communications?
IP is a common protocol and every computer understands this technology so it makes it easy to use for voice transmissions across computer networks.

3. What are the advantages and disadvantages of VoIP?
VoIP calls are cheap, whether it is an international or local call, the rates are pretty much the same. You only pay for the time spent on the internet and these are the fees paid to your ISP. There are no special charges for using VoIP. The main disadvantages of VoIP is that the voice quality is not as good as compared to traditional phone and there can be occasional breaks. In addition you need to have an internet connection in order to make a call and 911 identification is very difficult.

4. How is VoIP voice rated?
Voice quality is rated by a system called Mean Opinion Score (MOS) and standardized by ITU-T. The MOS is graduated on a 5 point scale with 5 representing highest quality.

5. How do I make a VoIP call?
The procedure for placing a VoIP call will depend on the type of equipment you are using. If you are using the PC to Phone/ PC to PC/Phone to PC system, you only need a PC, headset and internet connection to place the call. You simply use the dialing features available in Windows to click on the numbers you want to make the call. If you are using an IP phone, then the device comes with a regular telephone handset alphanumeric arrangement. You plug the Ethernet plug at the end of the cord of the phone to your PC and then press the appropriate buttons to make the call. If you have the ATA equipment, then you need to power it up, then place the phone jack at the end of the device into your regular phone, then dial the number you want.
