Internet phones have come a long way since the early days. A few years ago, you had to use software and a PC microphone to initiate a call from your PC to a regular phone. And you probably encountered some of the most garbled, inaudible conversations since tin can met string.
Thanks to advanced technology, the call quality of Internet phones has improved dramatically. The upsurge in affordable broadband service, combined with a new breed of hardware adapters, has led to a slew of Internet phone (aka Voice-over-Internet-Protocol, or VoIP) services eager to woo you away from your phone company. The Internet phone market includes telecommunications titans such as AT&T and Time Warner Cable, Net phone veterans like Dialpad and Net2Phone, and upstarts like VoicePulse and Vonage.
So is the Internet phone a viable alternative to your trusty landline? To find out, we tested eight broadband-phone services (see the chart "Internet-Phone Calling Plans: Choose Your Provider Carefully"). For one month we made a series of local, long-distance, and international calls, morning, noon, and night, and rated each service on its ease of use, audio clarity, and value for the money. Our verdict: Net phones vary considerably in price and performance, but the best--VoicePulse and Vonage--offer near-landline dependability, as well as a host of advanced features (voice mail, call forwarding, and so on) for much less money. (And as of press time, Net-phone customers pay minimal taxes and surcharges, in part because of the ongoing regulatory debate.) Still, we did encounter some setup problems and choppy calls.
Choice of Net Phones
Both hardware- and software-based Net phones are available. The hardware-based services give you two options: adapters (to which you connect your own standard phone) and all-in-one phone units (which include a built-in adapter). To use the hardware-based services, you must have a broadband connection. To get set up, you connect either hardware type to the router on your home network (via ethernet) or to your PC (via USB). Unlike the USB devices, the ethernet devices don't require that your computer be turned on before you can make a call. The purely software services, such as Skype and MediaRing, rely on a software program to handle the call.
The latest breed of hardware adapters delivers better audio quality than the software-based services do. That's because they're dedicated devices and don't share processing time with PC programs. Since the quality of some of the software services can be poor, we decided not to test them.
In our tests, getting set up was occasionally problematic. Some providers' sites make setup seem as though it will be a simple plug-and-play scenario. But when we tested the services with the Speedstream 5100 modem/router supplied with our SBC Yahoo Standard Plus DSL Service, none of the Internet phones worked. We learned that the Speedstream 5100 will not support the DHCP (Dynamic Host Configuration Protocol), which automatically assigns different IP addresses to the devices on our home network.
We then upgraded to the 2Wire HomePortal, a four-port router that supports DHCP, and had no further installation or firewall problems. (Note: If your network is running a firewall, you may need to grant the phone adapter access to certain Internet ports. Your Net-phone vendor should provide details on how to do this.) Bottom Line: If you're thinking about using an Internet-phone service, first confirm with your router manufacturer that your hardware is up to the task.
When you're ready to make a call, most services let you simply dial your number, and off you go. Some units, however, require you to press one or more keys before dialing. With the InternetTalker, for instance, you press the # key to activate the dial tone. The most laborious dialing sequence belongs to Earthphone, which forces you to complete a 17-key sequence before dialing a landline or cell number. For example, when we used the Earthphone 502 to call the PC World offices, we had to dial *799 001 124*2345*914152430500. Try memorizing that!
Clear Calls, Some Snags
Once our equipment was up and running, we were pleasantly surprised by the audio clarity overall. The quality was quite good in most instances, despite an occasional clipped syllable, echo, or muffled voice. Only a few people complained about the audio quality, which often was better than that of cell phones.
The glitches? In some Dialpad conversations, we couldn't hear the person we called. For unknown reasons, some Earthphone and TalkPro calls didn't connect. In fact, a handful of Earthphone calls were very choppy. Sy Richardson, Earthphone's president and founder, told us that we could address the problem by updating the Earthphone's firmware. But after we installed the update, the audio quality of our calls didn't noticeably improve.
Since Internet phones, unlike their landline cousins, aren't bound by geographical constraints, you can choose any area code. A homesick New Yorker living in Omaha, say, may opt for a 212 prefix.
Power outages are the bane of the Net-phone customer. Traditional phone networks provide their own power and deliver service during blackouts. But with Net phones, you're out of luck. One option is an auxiliary power source, such as a UPS, to run the phone adapter during an emergency; but that arrangement doesn't address broadband outages, which twice disrupted service in the midst of our tests.
Plans and Taxes
Net-phone providers generally offer service plans at about half the price of the Baby Bells. VoicePulse provides unlimited local and long-distance calls, with voice mail, for $25 per month. By comparison, SBC Communications charges nearly twice as much for a comparable landline-based plan. VoIP subscribers must pay federal and state taxes, but far less than the average landline customer, who faces a monthly barrage of nickel-and-dime fees and surcharges (see the chart "The Price Is Right: Cut Your Phone Bill in Half"). Most Net-phone companies do charge you for the required phone adapter; Vonage, however, provides its adapters for free.
Internet taxation is a hot topic in Congress, which is debating whether to continue its moratorium on taxing online commerce. For Internet-phone users, this translates into lower taxes than those paid by traditional-phone customers--at least for now. Will the party last? "[For] the next couple of years, [Congress] will take a hands-off approach" and allow the IP telephony industry to develop, predicts Daryl Schoolar, In-Stat/MDR senior analyst.
"The FCC is supportive of continuing the moratorium," says Jeff Carlisle, codirector of the Federal Communications Commission's Internet policy working group. At press time, the FCC had approved a proceeding inviting comments on how to regulate VoIP.
Net telephony isn't flawless, but the future looks bright. According to Charles Golvin, Forrester Research senior analyst, fewer than 150,000 of 106 million U.S. homes currently use Net phones. "By 2006 we'll have about 5 million VoIP lines in households," he predicts.
Someday Internet phones may deliver crystal-clear phone conversations that far exceed the standard set by today's regular phones. "On a network with [a speed of] 100 megabits per second [roughly 20 times that of a DSL connection], you can have voice calls that are better than CD quality," says Brian Willingham, a consultant with Long & Associates, a telecommunications consulting firm.
Take that, Alexander Graham Bell.
