At the core of free international calling apps is Voice over Internet Protocol (VoIP) technology. Unlike traditional phone services that rely on circuit-switched networks, VoIP uses the internet to transmit voice data. This technology converts voice signals into digital data packets and sends them over the internet to the recipient.
Here’s a simple breakdown of the process:
-
Voice Conversion: When dentist database you speak into the phone, your voice is converted into digital signals.
-
Data Transmission: These signals are broken down into small packets and transmitted via the internet.
-
Packet Reassembly: The recipient’s device reassembles these packets into voice signals in real-time.
-
Audio Output: The recipient hears your voice clearly, just as if you were speaking over a traditional phone line.
The reason these calls can be free is that internet transmission bypasses international telecommunication fees. Most of these apps require both parties to have the app installed for free calling, but some also cloud-based solutions for whatsapp lists offer the ability to call landlines or mobile numbers for free or at significantly reduced rates.
