VoIp (Voice over Internet Protocol) - An summary

You've probably at least heard of the word "VoIp", even if you didn't quite understand what all the excitement is about. VoIp stands for "Voice over Internet Protocol" and is going to change the way you think about production long length phone calls. Basically, VoIp technology turns analog audio signals (i.e. The sounds you hear when talking on your quarterly telephone) into a digital signal (which is then transmitted over the Internet.)

So why is VoIp revolutionizing the industry?

Cell Phone Backup

Because it means that by getting your hands on some of the free software that's ready right now, you can totally bypass your telephone company, and start production long length phone calls for free! This revolutionary technology has the ability to totally change the phone theory of the whole world! maybe you've seen television commercials for one of the pioneers of VoIp - Vonage. Vonage brands itself as the "broadband telephone company" and offers enticing perks to customers who switch to it's VoIp service such as low-cost 800 numbers and very cheap international rates (fees are waived from the U.S. To Canada, and international calls are as low as .03 cents a petite to overseas locations such as Paris). But Vonage isn't the only business who is concerned in harnessing the power of VoIp. At&T is setting up VoIp calling in several areas of the U.S. And there are other major VoIp players on the scene as well, such as Skype, who is relying on viral advertising to get the word out. Even some regional cable television associates are now gift VoIp telephone service at deep discounts to their customers.

One of the keen components about VoIp is that there's not just one way to make a VoIp call. There are as a matter of fact three ways to make a VoIp call:

1) VoIp via Ata: is the most ordinarily used VoIp method right now. Using the Ata (analog telephone adaptor), you join together your quarterly telephone to your computer or Internet connection. The Ata is an analog-to-digital converter and it takes the analog signal from your phone and converts it into digital data and transmits it over the Internet so you are able to make VoIp calls. This is how Vonage and At&T's CallVantage handle VoIp calls. The Ata is free with their services. And using an Ata for VoIp is so simple that anything can do it. Open the box, plug the cable from your phone into the Ata instead of the wall socket, and you're ready to begin production VoIp calls. Depending on your computer, where you live, and what type of Internet connection you have, you may need to also install VoIp software onto your computer, but this shouldn't be too difficult for most people.

2) VoIp via Ip Phones:VoIp phones look just like a proper telephone. They have a handset, cradles and buttons. But an VoIp phone uses an Rj-45 Ethernet connector instead of the proper Rj-11 phone connectors. VoIp phones join together directly to your router and all the hardware and software is already built inside to handle your VoIp calls. Look for Wi-Fi Ip phones to be ready in the near future, which will allow you to make VoIp calls from any Wi-Fi hotspot. This will allow you to take your VoIp phone with you when you travel, and stop in at any Internet café, hotel or other location where you can use your Wi-Fi laptop, and you can use VoIp technology to "phone home" from anyplace in the world.

3) VoIp via Computer-to-Computer:This is arguably the easiest way to use VoIp. There are no fees for long length calls and there are several associates gift free or low-cost software right now for you to make use of VoIp technology. All you need is the software, a microphone, speakers, a sound card and a broadband or cable Dsl Internet connection, and you can start using VoIp service right away. Except for your normal monthly Isp fee, there is no fee for any computer-to-computer VoIp call, no matter how far away they are. Http://www.skype.com is one such VoIp service. Chances are, you've already been using the VoIp technology without even being aware of it, any time you've made a long length telephone call recently. Many of the major phone associates are already using VoIp technology to cut their own bandwidth. It's a simple matter of routing thousands of phone calls straight through a circuit switch and into an Ip gateway. Once received on the other side of the gateway, the VoIp calls are decompressed, reassembled and routed back to a local circuit switch.

VoIp telephony is the wave of the future.

VoIp technology makes sense in terms of Roi, from both an economic and infrastructure point of view. It may take some time, but eventually all of the current circuit-switched networks that are in use today will be replaced by packet-switching VoIp technology. More and more businesses are already installing VoIp systems, and as VoIp technology makes its way into our daily language, our lives, and our homes, it will continue to grow in popularity. According to Forrester Research, nearly 5 million U.S. Households will have VoIp phone service by the end of 2006. The two biggest advantages of VoIp for home users are price and flexibility. Currently, most VoIp providers offer calling plans similar to that of cell-phone companies, which are ordinarily called "minute-rate" plans, for as petite as a month. And as with cell-phone plans, you can also get unlimited plans for nearby a month.

With the elimination of long-distances charges, unregulated charges, and all the freebies that come proper with VoIp service, it can as a matter of fact number to a critical savings for you. For example, you may be paying extra for features like:

· Call waiting

· Three way calling

· Call forwarding

· Caller I.D.

· Repeat dial

· Last call return with VoIp

These services come standard. Plus there are some industrialized features that make VoIp something worth finding into. With some VoIp carriers, you can set up call-filtering options and as a matter of fact have some operate over how calls from inevitable numbers are handled. For example, you can:

· transmit the call to a singular number

· Send the call directly to voicemail

· Give the caller a busy signal

(By the way, if you're concerned in any of these features, not all VoIp associates are created equal, so do a petite shopping nearby first, because VoIp prices and services do vary).

The second advantage that makes VoIp so keen for home and small business users is flexibility. With VoIp you can make a call anywhere you can get broadband connectivity. Since the VoIp phones or Atas broadcast facts over the Internet, they can be administered by any provider.
