The following list provides a glossary of terms and definitions that are commonly used in VoIP Solutions. This glossary list will provide a good reference for you during your introduction to VoIP Phone Services.
Analog audio signals: Analog audio signals are used to transmit voice data over telephone lines. This is done by varying or modulating the frequency of sound waves to accurately reflect the pitch of the sound. The same technology is used for radio wave transmissions.
ATA - Analog Telephone Adapter. A device that connects between an analog telephone and an Internet connection port, and allows you to use a standard phone to make and receive VoIP calls over the Internet.
Bandwidth: Bandwidth is the volume of data that can be transmitted over a communication line in a fixed amount of time. It is expressed in bits per second (bps) or bytes per. To get the most out of a VoIP service you really need broadband although even the slowest broadband will be OK for VoIP.
Broadband: It is a term used to define high speed Internet connection, generally provided by cable TV, DSL or dedicated telecom lines. The high speeds are achieved by the carrying capacity of the cable that can carry multiple messages simultaneously.
Cable modem: The cable modem is a device that is used to connect a computer to the high speed coaxial cable run by cable TV companies to provide access to the Internet. The connection is made through an Ethernet port, which is a shared medium and can affect download speeds if too many users log on simultaneously to the Internet on that particular cable segment. However, despite this cable modems provide extremely fast access to the net.
DSL modem: A DSL modem is a device that is used to connect one or more computers to the high speed DSL line provided by a DSL operator to gain access to the Internet. The customers use these modems to log on the net to download or transmit data. Since the DSL lines have high bandwidth capacity the data transfer speeds are very high.
E911: E911 is the short form of the term Enhanced 911, and is used for providing emergency service on cellular and Internet voice calls.
H.323: Another protocol used by some older VoIP services. H323 has largely been replace by SIP as the language VoIP uses. See SIP for more.

Make and receive calls to ordinary phones with your computer.Internet calling company.
IP address: An IP address, also known as Internet Protocol address, is the machine number used to identify all devices that are connected to the net. Each device has its own unique number which it uses to communicate. This number is fixed in the case of those computing devices that have a fixed IP address. The rest are allotted a dynamic IP address, which is valid for the period they are connected to the net. The numbers range from 0.0.0.0 to 255.255.255.255.
IP Phone: An IP phone is one that converts voice into digital packets and vice versa to make phone calls over Internet possible. It has built-in IP signaling protocols such as H.323 that ensure that the voice is routed to the right destination over the net. The IP phones come with several value added services like voicemail, e-mail, call number blocking etc.
IP telephony: IP telephony refers to the two-way transmission of voice over Internet. The voice is transmitted in real time by using the packet-switched technology over the IP network. Some of the applications that use IP telephony are IP-based phone services, voice over instant messaging and videoconferencing.
Net Phone or Net Calls: A net phone uses the Voice over IP technology to make voice calls. Another term for making telephone calls on the Internet and refers to the VoIP service.

At the receiving end the digital data is reconverted into voice and fed into the user’s phone.
Voicemail: It is a telephone messaging system that digitizes the analog voice signals and stores them on disk or flash memory in a central computer.
