PopTox is a browser-based VoIP software to make app to phone calls for free. Let’s keep in mind some key distinctions. The differences between traditional calls and VoIP calls lie in the type and length of transmission and the kind of devices used.įurthermore, VoIP can reach both internet applications and traditional phone lines. Similarly in VoIP software, your device captures your voice as a digital signal, routes it through the internet network as an Internet Protocol packet, then to the device you’re calling, and plays the digital signal received. Computer to telephone calls are made via internet network transmissions.

This back and forth transfer of data is how traditional calls work. When making calls from telephone to telephone, your device captures your voice transmission, routes it to a network, which then routes it to the device you’re calling, and plays your voice transmission. Telephone to telephone calls are made via phone network transmissions. VoIP means that your voice is captured by your computer and transmitted over the internet network to reach your recipient.Īs such, calling from your computer using VoIP is actually quite similar to traditional telephone calls. Calls through your computer’s internet connection use Voice over Internet Protocol ( VoIP).
