VoIP comes in two basic forms: hardware-based services that use a converter box between your broadband Internet router and a regular touchtone phone, and software-based services that require a computer. Major hardware VoIP services such as those from Vonage (News – Alert) and EarthLink fall into the first category. The software-based services, like GloPhone and GoogleTalk, are user-friendly descendants of the original hacker-level VoIP packages. These PC-based systems handle call-processing duties on your internet-connected computer instead of on a separate dedicated box or phone, and most lack complete call-and-receive interconnect services to public phone networks. You can use your computer’s built-in speakers and microphone, or inexpensive USB headsets and handsets.
Skype is in a category all its own, offering both free PC-based software and dedicated VoIP handsets with the software built in so you don’t need a PC to make calls. With Skype, calling to other Skype users is free, while the ability to receive calls from and make calls to outside phone numbers (Skype In/Skype Out) is available for a fee.
Software-Based VoIP
PC-based packages have greatly improved in sound quality over the years (especially if you have broadband access and a fast PC), but some are still not at the same level of quality or ease of use as the hardware services, so you will want to try before you buy. Some (such as the new GoogleTalk and Yahoo Messenger betas) only let you talk to other people using the same software, while others, such as Skype and GloPhone, also let you make and receive calls from regular phone users at extra cost. In addition, your PC must be on with the software open unless you use a dedicated handset, such as those available from Skype.
Many software-based VoIP packages are free or very affordable, however, and there are usually no call charges unless you want to be able to talk to regular landlines or cell phones. Calls to other VoIP users are usually free. The leader by far is Skype, with its SkypeIn and SkypeOut services bridging the gap to landlines. SkypeIn and GloPhone provide you with actual phone numbers you can give to anyone.
Hardware-Based VoIP
While PC-based VoIP software will continue to play a major role due to its near-free quality, most big cable and phone carriers offer hardware-based VoIP services in attractive package deals with their other services, on one monthly bill. Hardware-based systems usually offer higher voice quality, better reliability, and more features, especially those that relate to landline usage, such as white-page listings and 911 access. These systems allow you to plug a standard phone into a converter box, which in turn connects to your broadband modem or home router. Anyone can receive a call placed this way; no special software or converter box is required at the recipient end.
