So let’s get started…

How Does The Computer Initiate Calls?

For initiating a call computer’s internet connection utilizes Voice over Internet Protocol (VoIP). Your computer captures your voice and transmits it over the Internet to connect with your recipient. 

The functionality of VoIP calling is quite similar to traditional phone calls. When we make calls from telephone to telephone, your device collects your voice transmission and then routes it to the network, then again routes it to the recipient’s device and processes your voice transmission. This is the entire working functionality of traditional calls. 

VoIP software capture your voice in the form of a Digital Signal and routes it as an Internet Protocol packet via the internet network and then routes it to the recipient’s mobile and processes the digital signal. 

The significant difference between traditional and VoIP calls is the transmission length, type, and kind of devices being used for communication. Furthermore, VoIP can reach both dedicated internet applications and traditional phone lines.
