What is VoIP?

what is VoIP

Voice Over Internet Protocol, or simply VoIP, is an advanced telephony technology that enables voice, video, and message communication via the Internet, like WiFi, cellular data, and IP-based networks. 

VoIP enables users to collaborate, connect, and communicate with anybody, anywhere. All you need is a VoIP-capable device and a strong internet connection. With VoIP, you can make and receive calls on Smartphones (Android and iOS) and tablets. Laptop, desktop computer, and other similar devices. 

How Does VoIP Work?

VoIP functions in a very simple way. First, the voice or the analog data from the sender’s end is converted into digital data. This process is called “Analog-to-Digital conversion.” After the conversion, the digital data is transmitted into small packets and sent to the receiver via internet or IP-based networks.

After reaching the receiver’s end, the digital data packets are converted back into analog data. After the successful conversion, the receivers can use the analog signals. This is the complete cycle of the communication process in VoIP. This is a very sophisticated process. However, this telephony technology operates simultaneously and seamlessly. 

Advantages of VoIP

Incorporating VoIP can significantly improve communication and collaboration within a business. This telephony technology offers several advantages, and its significant highlights include cost-saving, scalability, mobility, and the availability of advanced features.
