All About VoIP

Voice over Internet Protocol(VoIP) is a technology which let everyone to make calls over internet using phone. It is most use technology, with the rise of broadband VoIP is more chosen by everyone- business persons and consumers.

You might be familiar to an IP address, that’s your Internet Protocol address. An IP address is how computers and devices communicate with each other on the internet. VoIP isn’t actually all that new. Telephony has relied on digital lines to carry phone calls since the late 90s. VoIP is a cost-effective way to handle an unlimited number of calls.

Old phone use analog lines to carry voice signals. If you want to make calls, you have to have extra wiring install. This is very problematic as it is not that you will get a good wire collection everywhere.

Many businesses rely on specialize hardware for phone service. This equipment is known as a Private Branch Exchange (PBX). It connects internal phone extensions to the public telephone network. PBXs are generally quite costly to set up and maintain.

Working of VoIP

This network works on the internet, in the form of data packets all the voice messages are send.

Here are steps that how VoIP network works:

  1. Your phone connects to your or router in your Local Area Network (LAN).
  2. When you dial a telephone number, your IP phone tells your VoIP service provider to call the other party.
  3. Your VoIP service establishes the call and exchanges data packets from your IP phone.
  4. Your VoIP phone converts these digital signals back into the sound you can hear.

Cloud-based PBXs are responsible for features like voicemail, conferencing, and call routing. When you think about it, they act as their own full-service phone companies that you control.

  • Needs a high-speed internet connection – VoIP doesn’t work well on dial-up or satellite-based internet connections. You’ll need at least 100 kbps (0.1 Mbps) per phone line.
  • Emergency services limitations – In the unlikely event you need to call 911 from your VoIP phone, you need to tell the operator your actual location. Voice over IP systems default to sending your company’s mailing address to public safety operators.
