SIP Signaling

SIP (Session Initiation Protocol) signaling is a method used in internet-based communication, such as VoIP calls, to establish, modify, and terminate sessions. Think of it as the set of digital "handshakes" that coordinate how devices connect and communicate, similar to how a phone call setup works traditionally. SIP handles tasks like ringing, answering, and ending calls, ensuring both parties are connected correctly. It doesn't carry the actual voice data; instead, it manages the signaling that ensures the communication session is properly established and maintained between devices over the internet.
