Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number – including local, long distance, mobile, and international numbers. Also, while some VoIP services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter.
Its advantages over traditional telephony include:
- lower costs per call, especially for long-distance calls
- cost free branch to branch internal calls
- lower infrastructure costs: once IP infrastructure is installed, no or little additional telephony infrastructure is needed.
- new advanced features
