What Is VoIP and How It’s Revolutionizing Business Communication

How VoIP Works

1. Voice Conversion: Your voice is converted into digital data using a codec.
2. Data Transmission: That data is sent over the internet to the recipient.
3. Signal Conversion: On the receiving end, the digital data is converted back into sound.

You can use VoIP with:

• Desktop or mobile apps
• VoIP desk phones
• USB headsets with softphones
• Web browsers with integrated calling tools
