What is VoIP?

What is VoIP?

VoIP is an acronym that stands for Voice over Internet Protocol but it can also be referred to as Internet Calling, IP Telephony and Internet Telephony. Those who use a VoIP application can make calls with just an internet connection and some type of microphone and speaker. It has been one of the most successful and widely used technologies in the last decade. VoIP is a combination of software that allows people to be able to use the transmission medium of the Internet to make and receive calls.

This is achieved by transferring a person’s voice as packets of information from one IP to another instead of using a phone’s circuit transmissions. VoIP uses specialized media delivery systems that transport audio by encoding it with both audio and video codecs. This optimizes the stream of the media.

Early VoIP applications mirrored traditional phone systems in their models but now VoIP applications are creating custom networks for their members. Companies such as Skype have a closed network as a way to give their users free calls while also having the ability to charge users access to their other communication networks. Google Talk on the other hand has implemented a federated VoIP that connects users on two separate domains by a dynamic interconnection. Each VoIP is different.

Advantages of Using VoIP

One of the main advantages VoIP has over a traditional phone system is how flexible it is. Those implementing VoIP can use it where ever they are as long as they have a connection to the internet, a microphone and a speaker. This means users can make calls at work, at home and even in different counties. Another one of the advantages of VoIP is its cost. A large percentage of VoIP applications are completely free. This can include calls that are made to different counties that would normally have an additional charge when using a traditional phone system. The diminished cost of VoIP has made it a standard practice in workplaces. More and more companies are turning to VoIP applications over other costly options.

Choosing the Right VoIP

There are several VoIP options available for the public to use, but as mentioned before each VoIP is different, which is why it is a good idea to take a look at VoIP reviews if you are not entirely sure of what you specifically need. Though most have decent or better call quality and similar features one of the most important things to look for when installing a VoIP application is how secure it is. The security of a VoIP is about the same as other Internet connected devices which means that they can be hacked. If a VoIP application does not have suitable protection hackers can find user data, deny services and record conversations. Some ways to secure VoIP is by using a classified network or by adding a Secure Real-time Transport Protocol, a Voice over Secure IP or by using Type 1 encryption. Most popular VoIP companies will have enough encrypted security to protect their users. Users can also protect themselves by being careful about what information they have connected to their VoIP application.
