How does IP telephone work？
VOIP calls are delivered in three key phases. These are:
1) Audio is digitised
When you talk to the device's microphone, the audio signal will be digitized by the VoIP application. After that, the data is decomposed into data blocks and each data block is given a unique label.
2) Data travels over the internet
Your call is made up of different packets of data. Each packet of data travels over the Internet to the recipient.
3) Data is decoded and reassembled
When the data arrives at the final destination, it will be grouped in the correct order. Then, the data will be converted to audio, and the recipient will hear what you say and receive the content in your voice.
It is worth noting that the data packets don’t necessarily arrive in the order they were sent. Because VoIP ensures that each data packet is routed to the recipient using the most efficient route across the internet. In this information-rich era, efficiency is particularly important. IP Telephone gives us a quick and flexible experience.
