Call Signaling

Call signaling is a process used in telecommunications to establish and manage a phone call or communication session between parties. It involves exchanging specific signals or messages that indicate a call setup, user intentions, and call termination, allowing devices and networks to coordinate and connect properly. Think of it as the communication protocol that tells the network, "I want to call this number" or "hang up now," ensuring that the connection is correctly initiated, maintained, and terminated throughout the call.
