What is VOIP? How Does it Work?

[ad_1]

Voice over Internet Protocol, or simply VoIP, is a technology that allows voice calls to be made over any internet connection. Aside from voice calls, VoIP offers many additional and advanced features that make it the choice for today's fast growing businesses. A major feature of VoIP is that users are able to make long-distance calls at almost zero cost. Aside from the internet service provider fees, there is usually no additional cost to be able to use VoIP.

It is very simple to use VoIP. The user connects to the internet using any of these units (computer, VoIP telephone, mobile phone, mobile device), and all the data transfer happens in cyberspace, while the destination may be any of the above mentioned units. For businesses however, a recommended solution is the installation of a VoIP system in the office, wherein all required connections can be easily made via the local area network. Outsiders may either dial in directly to a specific number to reach someone, or they may need to dial an extension number, much like how the PABX system works.

In particular, VoIP works using packet switching. Essentially, packet switching is done by digitizing and encrypting the voice of the caller into data packets, and then sends it through the internet connection. The packets go through several routers until they reach the destination, where they are decrypted and decoded for the other person to receive the message.

VoIP works by converting voice into digital format and sending them as data packets over the internet connection. VoIP mainly refers to the protocol or the process by which voice conversations are facilitated via broadband data connections. There are several ways to do this. You can either:

o use an analog telephone adapter (ATA) so you could use a regular telephone and connect it to your computer, which is then connected to the internet;

o use an IP phone, which is a special phone that directly connects to the internet using an RJ45 adapter connecting directly to a router;

o connect via special software in your computer, which is the easiest and most cost effective way to use VoIP. The special software is also referred to as "softphones".

This means that there are different options for different needs. Most homes and small businesses are content with using softphones, while larger businesses typically integrate the VoIP voice sockets when they wire their office networks where they could plug-in the IP phones. The infrastructure needed does not cost much, as putting up the VoIP sockets is just similar to installing sockets for the computer LAN connection.

VoIP is a revolutionary technology that specifically puts its users to an advantage by providing advanced yet cost-friendly solutions to make communications to any part of the world possible.
