If you have never considered VoIP, it is time to reconsider your long-distance calling plan. VoIP is a technology that converts analog audio signals into digital signals which can be transmitted over the internet.
What this means is that if you are already subscribed to a monthly internet connection, you can utilize this connection to make free phone calls. This is enabled by using VoIP software which allows you to place free calls over the internet. You will essentially be able to go around the phone companies and their exorbitant charges.
VoIP is not a new technology but slow internet speeds inhibited its growth. However, with the recent burst of high-speed internet access all around the globe, VoIP has gained immense popularity. In fact, even the major telephone carriers are implementing their own Review VoIP calling packages across the country, which is a testament to the effectiveness of this technology.
This post will discuss what VoIP is, how it works, and why you need it in your business.
What is VoIP?
The acronym stands for Voice over Internet Protocol. This is a phoning technique that utilizes a group of technologies such as SMS, fax, voice, and video calls to deliver voice and media over Internet Protocol networks.
And even though these types of communications traditionally took place over public switched telephone networks, Voice over IP specifically transmits these communication services over the open internet.
So, How Does IP Telephony Work?
Whenever you utilize a VoIP service to make a call via the internet, your voice is converted into digital data, and then that data is re-converted to its original analogous form on the other end of the line. This process of conversion is only made possible by utilizing codecs. The conversion involves encoding the voice into a digital form then decoding it to an analog form so that the receiver hears your voice. Thus, codecs refer to the process of encoding and decoding.
Codecs make sure that data is compressed so that it can travel fast thus ensuring that call-quality is not compromised.
Therefore, codecs are needed because unlike in traditional telephony where phone calls rely on analog signals being transmitted in their raw form, VoIP can only use digital signals. Codecs, therefore, encode analog voice data into a digital form that can be transmitted over the internet. Upon reaching its destination, the digital signal is decoded to its analog form, so that the other person can hear and understand you.
Now, if you are both using a VoIP protocol, your entire phone call’s journey shall take place comfortably over the internet. But if they are using traditional networks, your call will travel as far as it can using VoIP, and then switch to the other person’s public phone network so that it can reach them.
