Many people are doing just that. But keep in mind that there are some disadvantages to using VoIP as your exclusive phone line. These include:

• If your internet connection is down, you lose your phone service also;
• Only some VOIP providers offer 911 emergency calls;
• While voice quality is almost as good as with traditional phone lines, there are occasional glitches such as echoes and slight delays;
• If you can't get a phone number in your local area, your neighbors' calls to you will be long distance for them;
• If your broadband connection is DSL, you will probably still need a traditional phone line into your home;
• Your phone number will not appear in the phone book or directory assistance;
• Downloading a large file off the internet while on the phone can cause significant call degradation, or cut the phone call altogether. Low-cost routers are available that prioritize a VOIP connection to eliminate this problem.
