Q: What Are Some Advantages of VoIP?
A: Some VoIP services offer features and services that are not available with a traditional phone, or are available but only for an additional fee. You may also be able to avoid paying for both a broadband connection and a traditional telephone line.

Q: What Are Some Disadvantages of VoIP?
A: If you’re considering replacing your traditional telephone service with VoIP, there are some possible differences:
• Some VoIP services don’t work during power outages and the service provider may not offer backup power.
• Not all VoIP services connect directly to emergency services through 9-1-1. For additional information, see VoIP & 911 Advisory.
• VoIP providers may or may not offer directory assistance/white page listings.

Aspects of these considerations may change with new developments in internet technology. You should always check with the VoIP service provider you choose to confirm any advantages and limitations to their service.

Depending upon your service, you might be limited only to other subscribers to the service, or you may be able to call anyone who has a telephone number – including local, long distance, mobile, and international numbers. If you are calling someone who has a regular analog phone, that person does not need any special equipment to talk to you. Some VoIP services may allow you to speak with more than one person at a time.

A broadband (high speed Internet) connection is required. This can be through a cable modem, or high speed services such as DSL or a local area network. A computer, adaptor, or specialized phone is required. Some VoIP services only work over your computer or a special VoIP phone, while other services allow you to use a traditional phone connected to a VoIP adapter. If you use your computer, you will need some software and an inexpensive microphone. Special VoIP phones plug directly into your broadband connection and operate largely like a traditional telephone. If you use a telephone with a VoIP adapter, you’ll be able to dial just as you always have, and the service provider may also provide a dial tone.

VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. In addition, wireless “hot spots” in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.
