VoIP lets you make voice calls over the internet instead of traditional phone lines. This beginner’s guide explains how it works and why SaaS telephony platforms like CallHippo are replacing legacy phone systems.
What is VoIP?
VoIP (Voice over Internet Protocol) is a technology that lets you make voice calls using the internet instead of traditional phone lines. If you’ve used WhatsApp calls, Zoom, or Skype, you’ve already used VoIP.
How does VoIP work?
VoIP converts your voice into digital data packets, sends them over the internet, and reassembles them at the other end so the listener hears you clearly.
You can use VoIP through:
- VoIP desk phones
- Softphone apps (computer or mobile)
- Web dialers (like CallHippo)
Why do businesses use VoIP?
