Signalling – Peer-To-Peer Connection
Signalling Websockets are used to set up call connections between the client servers. The client connection must adapt to each other by sending messages, data and media over the public IP address of both the clients webrtc signalling servers. To get the IP address, We use STUN Server.

Initially, both video and voice call functionalities depend on the streaming media between two client servers connected to each other. 
Voice Over Internet Protocol (VoIP) is one of the most familiar and trusted standard techniques for voice and live video chat apps over the Web.
