Voice over Internet Protocol (VoIP) is a method for the transmission of voice via the Internet. To clarify, VoIP gives the ability to make voice calls and text messaging through the Internet. This is also known as Broadband Phone, Internet Telephony, Voice over Broadband or IP Telephony. The providers of this service use different technologies for transmitting voice signals over an IP network on the Internet. The service allows users to call nationally and internationally for little to no costs.
Using VoIP for calling dates back to 1973, when the voice signals were transmitted through the Internet for the first time. Then, in early 1980s, this technology became available to the public. Currently this service is very popular in the United States and across the world.
How it Works
VoIP converts the voice messages of the caller and receiver into digital signals. The digital signals then travel via the Internet. When you make a call using a regular phone, the signals are converted into regular telephone signals before they reach their destination. With VoIP, a call can simply be made from your computer, special IP-phone or a cell phone with an app that makes VoIP calls and messages. This technology requires broadband Internet connection via a cable modern, or other Internet services including wireless Internet connection (Wi-Fi) and data connection from a network service provider.
Using VoIP for calling is an easy process. The only thing you need is a computer or cell phone. You also need a microphone and speakers to enable the actual conversation.
Cheap VoIP Calls
VoIP has been acknowledged as a “least cost routing” (LCR) system. This is because VoIP “routes” calls to their actual destinations via the shortest route possible. When compared to calls made over the public switched telephone network (PSTN), VoIP can actually facilitate tasks and also provide services with lots of ease. For example, VoIP can transmit more than 1 telephone call over the Internet at the same time. Therefore, VoIP is the better and less expensive option when it comes to adding new telephone lines.
VoIP also provides users with services like automatic redial, call forwarding and conference calling. This service offers numerous zero or near-zero-cost features where other services charge an extra fee. This means, VoIP is much cheaper compared to other service providers. Moreover, VoIP can be integrated with the users’ current Internet services such as address book management, file exchange and audio conferencing.
There are no charges to make calls to another subscriber using the same service. If the user wants to call someone who is not using the service, wants to call a domestic or international landline or cell phone, some charges will incur. However, some VoIP service providers allow their customers to make calls anywhere at a specific low-cost flat rate.
Although there are many advantages of using VoIP for calling, the technology has had a few reported issues like insecurity and inconsistent call quality. However, VoIP is a great service because it allows users to save money and may even allow users to eliminate their high landline or cell phone bills.
