VoIP phones, such as the VTech IP8100 (pictured), have the look and feel of traditional phones, but they send and receive data through the Internet.
The number of companies providing broadband phone service—also called Voice over Internet Protocol, VoIP, Digital Phone Service and Internet Phone Service—has been growing steadily over recent years. The number of subscribers is also on the rise. There were an estimated 5 million VoIP subscribers in 2004 and some studies predict that number will reach closer to 60 million by 2010. Given the prevalence of broadband service to homes across the world, it is not a far stretch to imagine a day when the standard phone line goes the way of the telegram.
How VoIP Works
VoIP calling uses a broadband connection to send voice data from caller to caller. When a caller speaks into the phone or computer, an analog audio signal is converted into digital data and sent across the Internet to a receiving person on other end. The technology essentially treats a spoken conversation like an email. With VoIP, anywhere one can access the internet, one can make a call. Placing a call over broadband is accomplished in a few ways:
VoIP Consumer Questions
What should you be looking for in a VoIP service? Start by assessing service plan costs, which will look like a traditional phone service or cell phone plan. Plans might offer so many minutes per month, unlimited local and long distance, international calling, etc. Additional costs, like activation fees, shipping fees for equipment, taxes and surcharges, and cancellation fees should be considered as well.
Promotions are popular and varied with VoIP companies. Look for one or more free months upon sign-up, free equipment (like an adapter kit, VoIP phone, or cordless phone), or waived set-up fees. Like cell phone service providers, some VoIP providers will insist on a one-year commitment to their service. Additional features like voice-mail, caller ID, and the usual complement of phone service options may or may not be included in service plans. Customers might also want to keep their existing phone number, and will want to assess this possibility.
Some VoIP service providers offer some pretty neat features, like one-click calling, call-logs, and phone and address books that can be accessed and managed through the computer.
“Vonage’s Voicemail Plus feature allows the customers to receive their voicemails via email ... and all account activity is available online,” says Meghan Shaw, public relations specialist with Vonage. It might also be possible to choose a new phone number with any area code—handy for callers who dial a certain area code frequently and only want a local calling plan. Bundled services from companies like Verizon (broadband Internet and VoIP phone) and Comcast (Internet, cable television, VoIP) might offer additional incentives and consolidated bill-paying.
VoIP Providers At a Glance
With more than 1,000 VoIP service providers, we’d be here all day if we listed them all. Instead, we selected a handful from some of the better-known companies—as well as a few lesser-known—to compare their unlimited local and long distance service plans, as well as some of their included features ... or included costs. Like any phone service plan, companies will adjust rates and alter plan options to keep up with the competition. When shopping for a service provider, take the time to compare features and costs.
VoIP Caveat: 911 and Interrupted Service
Before signing up for VoIP service, consumers should be aware of the 911 limitations of these services. These limitations should be made very clear by the VoIP companies—the Federal Communications Commission has mandated that such information be provided.
Because VoIP service is dependent upon an active broadband connection and a power supply, loss of either of these can result in an inability to place a call. This becomes an issue in the case of an emergency. Consumers will therefore want an additional means of reaching 911 services (cell phone or landline) in the case of interrupted power or Internet connections. Furthermore, although some VoIP services allow costumers to select a phone number with an area code different from the one in which they live, providing an accurate home address is vital (and required) for emergency service purposes. Consumers will want to evaluate if and how a potential VoIP service provider will handle emergency 911 calls.
Some companies have found creative solutions to the interrupted service issue. Vonage, for example, will automatically forward incoming calls to a designated number if the broadband connection is down.
