This is one of the main reasons why Voice over Internet Protocol, commonly known today as VoIP, is now replacing analog phone systems.

VoIP was initially expensive; not even the largest Corporations could afford this technology. Today, however, even small businesses take advantage of VoIP. What poses as a challenge now for most professionals who are used to the Analog Phone System is understanding terminology used by telephony experts.

Get familiarized with these buzz words so you can be more specific in discussing your business requirements to a VoIP expert. Below is a list of terms that anyone would most likely come across regarding VoIP:

Unified Communications (UC)

In the effort of making business communication more convenient, it is integral to have just one service to govern all forms of communication. This is what Unified Communications is all about. Also known as UC, Unified Communications includes telephone, email, fax, instant messaging, etc. all in one network.

VOIP (Voice over Internet Protocol)

This technology allows an individual to make voice calls using an Internet connection. This is different from a regular phone line, also known as an analog phone line. Some VoIP services are limited: this means that you and the person you are calling must be subscribed to the same service. Most VoIP providers today allow you to make calls, from local to international numbers. VoIP services may also require an adapter, a VoIP Phone or a computer.


This is an electronic device that converts existing analog phone lines and network infrastructure to VoIP. Should your Company be using outdated technology and one of the departments has migrated to a new one, a gateway can connect these two networks with ease. There are different kinds of gateways: analog, digital and GSM.

Analog Gateway

An Analog Gateway is a device that converts legacy phone system, analog line, analog phones and fax machine to VoIP phone system

Digital Gateway

A Digital Gateway is a device that converts your legacy phone connection such as E1/T1/PRI to VoIP phone system.

GSM Gateway

A GSM Gateway is a device that requires a SIM card to connect to mobile carriers.

PBX (Private Branch Exchange)

PBX is the telephone system used within a company. PBX systems usually use to share a certain number to make outgoing calls.

IP PBX (Internet Protocol – Private Branch Exchange)

IP PBX is, simply put, a PBX System that helps companies toggle between different lines (analog, VoIP, etc). Companies choose IP PBX since its features include transfers, voicemail, voice menus (IVR), among others. With the use of other systems like VoIP, ISDN or analog anyone in the company can communicate with telephone users outside it. Should you want more than one physical phone line or free calls between users, the IP PBX allows this to happen.
