Is VOIP Too Good to be True? Weighing the Advantages, Disadvantages of VOIP

If VOIP is such a great thing, why isn’t everybody using it? Well, for starters the bandwagon is crowded—there are lots of VOIP broadband phone providers out there. The other thing is there are some drawbacks to VOIP.

For instance, during power outages, you’ll have no Internet connection, and therefore, no phone service. In other words, no power, no phone.

So if the downsides are so well known, the real question is, what are all these hundreds of VOIP phone companies doing about them?

VOIP Advantages

First, we have an expectation that VOIP has many advantages over regular phone service.

Low cost. If you have a broadband Internet connection (DSL or cable), you can make PC-to-PC phone calls anywhere in the world for free. If you wish to make a PC-to-phone connection, there’s usually a charge for this but probably much cheaper than your regular phone service.

You can pay as you go or you can sign up with a VOIP service provider and pay a monthly fee in return for unlimited calls within a certain geographic area. For example, some VOIP services in the United States allow you to call anywhere in North America at no extra charge. Overseas calls are charged at a relatively small rate.

Portability. You can take your cheap phone service with you and make and receive phone calls wherever there is a broadband connection simply by signing in to your VOIP account. This makes VOIP as convenient as e-mail.

If you are traveling, simply pack a headset and use your laptop plugged into the Internet, or plug a VOIP phone directly into the Internet connection and you can talk to your family or business associates for almost nothing. If you don’t have a VOIP phone, use an analog terminal adaptor (ATA) to connect a regular phone to the Internet. Today you can find ATAs that small, portable and inexpensive. A great idea for frequent travelers.

Phone-to-phone VOIP is also portable. When you sign up with a VoIP service provider the Internet phone or adaptor that is used with that service is assigned a unique number. This ‘phone number’ remains valid even if your VoIP service is in Cleveland and you are connected to the Internet in Bangkok. An Internet phone is small and light enough to take with you anywhere. Simply plug it into a broadband connection anywhere in the world and you can make and receive calls just as though you were in your own home or office.

Features. Unlike regular phone service which usually charges more for extra features, VOIP comes with a host of advanced communication features. For example, call forwarding, call waiting, voicemail, caller ID and three-way calling are some of the many services included with VOIP telephone service at no extra charge. You can also send data such as pictures and documents at the same time you are talking on the phone.

VOIP Disadvantages

If VOIP is starting to sound really good to you, make sure you understand the following downsides as well.

No service during a power outage. During a blackout a regular phone is kept in service by the current supplied through the phone line. This is not possible with IP phones, so when the power goes out, there is no VOIP phone service. One solution to this problem is to use battery backups or power generators to provide electricity.

If you decide to continue subscribing to a regular phone line as an emergency backup, consider that monthly cost cuts into your overall VOIP savings. However, VOIP would still make sense in this case if your home or business made significant long distance calls.

Emergency 911 calls. Another major concern with VOIP involves emergency 911 calls. Traditional phone equipment can trace your location. Emergency calls are diverted to the nearest call center where the operator can see your location in case you can’t talk. However, because a voice-over-IP call is essentially a transfer of data between two IP addresses, not physical addresses, with VOIP there is currently no way to determine where your VOIP phone call is originating from.

To solve this issue, the E911 standard by law mandates that VOIP service providers pass name and address information to the nearest Public Safety Access Point (PSAP) when 911 is dialed. Not all PSAPs in the country support E911 yet, so you should ask when deciding on a VOIP service provider, if E911 is supported in your area.

Reliability. Because VOIP relies on an Internet connection, your VOIP service will be affected by the quality and reliability of your broadband Internet service and sometimes by the limitations of your PC. Poor Internet connections and congestion can result in garbled or distorted voice quality. If you are using your computer at the same time as making a computer VOIP call, you may find that voice quality deteriorates dramatically.

Bad or unreliable internet connections can result in poor voice quality, such as clipping, voice delay, or dropped calls. And emergency 911 service may not work as you expect.

For example, you can expect to save significantly on long distance charges. And, if you are happy to make and receive calls on your computer, you won’t likely have to pay a cent beyond the cost of your regular Internet connection.
