VoIP
VoIP stands for Voice over Internet Protocol, and refers to the technology that transmits voice via Internet in the form of digital data rather than phone lines. Here's how it works: the caller speaks into his phone, his voice is then stored as data packets and sent over the Internet, and then converted back to voice at the other end of the receiver, allowing the other person to to hear what was said. Although it sounds complicated, VoIP works like a telephone line - there is no shift in the call. Similarly, you can call a number (mobile or telephone) with VoIP.
IP
You may have heard of intellectual property, but never really took the time to understand what it means and what it can do for you. IP stands for Internet Protocol and describes how data packets are transferred between source and destination. In the most basic sense, IP is the mode of communication between computers on the Internet. Each computer has its own unique IP address that identifies the rest. IP is just in the acronym VoIP and this is because the voice data you transmit in each call is sent to the Internet protocol address that is specific to each caller.
Bandwidth
bandwidth in VoIP terminology refers to the potential volume of data that can be transmitted via a communication line in a predefined time. Bandwidth is usually called in "bits per second" or BPS. When you sign up to a VoIP service, you usually ask that the bandwidth of your home or office currently uses. If you are not sure what it is, you can always ask your ISP. When you sign up to a VoIP service, it is helpful to know how much bandwidth you have functional so you can ensure that your service will run smoothly.
Analog Telephone Adapter (ATA)
An ATA is a device that connects traditional analog telephones and fax machines to a VoIP system. Like most business VoIP services require IP phones, ATA is generally used by VoIP home users. The configuration often varies according to the ATA mark, but generally you will connect your analogue telephone to the ATA, then use an Ethernet cable to connect the ATA and your router or modem.
Modem and Router
The modem is the device that establishes and maintains the connection to your ISP. It also converts the signals to and from your router. The accompanying router that comes with your modem is the device that acts as an intermediary between the modem and the devices using the Internet. It also keeps track of computers or other devices are connected to the Internet, and monitors traffic or internal communication between a computer and a printer, two computers or other devices. Note that most modern appliances issued by broadband ISPs function as both a modem and router.
Firewall
A firewall may be something you've met before in your technical trips, but it is important to know what role it plays in your VoIP system and the use. A firewall is a network security system (hardware or software) that controls the network traffic in and out on the basis of a set of predetermined rules. If your router comes with a firewall version, you may need to organize the ATA so it's out of the firewall configuration to make sure it does not affect your service.
Having a good vocabulary which comes repeatedly when using a VoIP system is a great way to ensure you get the most out of the service you are using. Even for those VoIP veterans and have been using the technology for years, a brief review of terminology is a good idea from time to time so that you can ensure that your service performs the way you would like that it and what areas you want to focus on specific development. Although we have only covered the basics of VoIP vocabulary in this list, users should be invited to make their own thorough research - our VoIP FAQ can be helpful -.
