Signaling System 7 (SS7)

Signaling System 7 (SS7) is a global telecommunications protocol that manages and routes calls, texts, and data across networks. It operates behind the scenes, handling tasks like setting up and tearing down calls, routing messages, and providing added services such as caller ID and billing. SS7 enables different phone networks to communicate seamlessly and securely, ensuring reliable and efficient connections. It works independently of the voice channels you use, relying instead on a dedicated signaling network to coordinate and control communication services across the phone system.
