VOIP (Voice over Internet Protocol) - allows you to make telephone calls using a computer network in very simple way . It converts the voice signal from your telephone into a digital signal thats why you can speak to anyone with a regular phone number. You can change the way you think about long-distance phone calls. People generally like to use the new technology because its costs are less than traditional phone Below are listed some of the advantages and disadvantages of using VOIP .
VOIP offers you:
Lower costs per call, especially for long-distance calls VOIP can reduce international call tolls by as much as 40%. You can talk with many people at the same time without any additional cost. The call can be made to a local number, a mobile phone, to a long distance number or an international number without any additional cost. You can also use services that are not available with a traditional phone you can send data, like pictures and documents while talking on the phone. As long as you have access to a broadband connection you do not need to pay for roaming or long distance charges wherever you travel. Thats why the VOIP is very important in business. You have also ability to receive internet phone calls anywhere you are, as long as you are accessible to the internet. One of the various advantages is that many services such as caller id, call forwarding, call waiting, three way calling, and voice mail features often come standard with most VOIP plans. Unfortunately I have to report some problem with the integration between VoIP system and Internet. The main problem is as you can imagine voice data communication must be a real time stream (you couldn't speak, wait for many seconds, then hear other side answering) - the risks involved with poor internet connections, lost signals, and dropped data packets. Below are listed of some other problems of using VOIP:
1. Not all VoIP services connect directly to emergency services.
2. The risks involved with poor internet connections, lost signals, and dropped data packets.
3. It only works if your computer is switched on and the VOIP software is running.
4. The other person with whom you are trying to communicate with has to get the same program loaded and running on his computer.
5. Poor quality of the sound- phone calls often have lot of delay with lot of echo.
6. To get lower bandwidth you need additional processing power that makes digital phones more expensive than analog phones.
7. You must have a DSL router or a second computer set up to run a second phone line. With traditional phone services, a phone jack is in almost every room.
