Reference:
The statement that a WebRTC phone can be used even when disconnected from the cloud is incorrect. A WebRTC phone is a browser-based phone that runs in a supported web browser and connects to Genesys Cloud CX cloud services via WebRTC protocol. A WebRTC phone does not require any additional hardware or software apart from a supported browser and a headset or microphone/speaker device. However, a WebRTC phone cannot be used when disconnected from the cloud because it relies on an internet connection to communicate with Genesys Cloud CX.
