How does a WiFi IP phone work?

 A wireless VoIP (Voice over Internet Protocol) phone operates by converting voice signals into digital data, which is then transmitted over a Wi-Fi network instead of traditional phone lines. It connects to a VoIP server through the internet, allowing users to make and receive calls from anywhere with internet access, using an assigned IP address. 

The WiFi IP phone will need to be SIP registered to a SIP server or hosted SIP service provider for VoIP calls.
