ITG VoIP Primer

What is VoIP?
Voice over Internet Protocol (VoIP) is a technology that allows us to make voice calls through a broadband Internet connection instead of over a regular (or analog) phone line. VoIP calls can be made using a traditional phone connected to a VoIP adapter or a soft phone on a microphone-equipped computer. Because VoIP phone calls are routed through the Internet, rather than through a traditional service provider infrastructure, the routing overheads are virtually eliminated resulting in lower operating costs and hence cost savings that can be passed on to the consumer.

What equipment is required by the consumer to implement VoIP?
To connect a regular phone to the internet, an active broadband (high speed Internet) connection and an adaptor are required. (To connect more than one device at a time to the Internet, such as a phone and a computer, a router is also required.) To use a softphone on a computer, software and an inexpensive microphone are required.

What equipment is required by a business to implement VoIP?
In a business setting, through an IP enabled PBX (Private Branch Exchange), IP phones that can plug directly into a broadband connection are required. IP enabled PBXs are phone systems that provide advanced telephony features and services between VoIP and PSTN networks. Common features and services include: call transfer, conference, voicemail, music-on-hold, auto-attendant, and auto call routing. These services are also available, usually more economically, through a Virtual PBX (VPBX), a software version of an IP enabled PBX.

Who can receive a VoIP call?
VoIP consumers can call anyone who has a telephone number; this includes local, long distance, mobile, and international numbers. No special equipment is required to receive the call.

Is VoIP mobile?

1. Can Phone Adapters go wherever the user goes?
Yes, the adaptor can be used wherever a high speed Internet connection is available.

2. Can users select an area code in a different area?
Yes, users are not restricted to the area codes where they live, although the people who call you may incur long distance charges depending on their area code and type of phone service.
