How does VoIP work?

When a call is placed with VoIP, voice is transformed into electrical signals and then converted into binary through a codec software. The binary data is further broken down into “packets” by your operating system. Your computer sends these packets to another computer through the IP network, where they are processed by another codec software and transformed back into voice for the person on the other end of the line.

If the VoIP call is placed to a cell or landline number (and not a computer), it goes through a private telephony platform like Twilio or Voxbone. These platforms convert the signal so it can be sent to a regular phone line.
