The process of coordinating communication between peers before establishing a direct connection. In WebRTC, signaling involves exchanging session descriptions (SDP offers and answers) and ICE candidates between peers. The signaling channel itself is not defined by WebRTC — developers commonly use WebSocket, HTTP, or SIP for this purpose. In SIP, the INVITE method handles signaling for VoIP calls.
