FAQs

What is Signaling System 7 (SS7)? Signaling System 7 is a set of telephony signaling protocols used to set up and tear down telephone calls, perform number translation, prepaid billing, and other functions in public switched telephone networks. It operates out-of-band, meaning signaling is separate from voice channels, enhancing efficiency and reliability.

How does SS7 work? SS7 works by using a packet-switched network to exchange control messages between network elements such as switches and databases. These messages manage call setup, routing, billing, and supplementary services like call forwarding, ensuring seamless communication across networks.

What are the security risks associated with SS7? SS7 has known vulnerabilities that can be exploited for eavesdropping, location tracking, fraud, and intercepting messages. These risks arise from the protocol's design, which assumes a trusted network, making it susceptible to attacks if proper security measures like firewalls and monitoring are not implemented.

Is SS7 still used today? Yes, SS7 is still widely used today, especially in legacy telephone networks and for interoperability with modern IP-based systems. It remains critical for services like roaming, number portability, and SMS in many parts of the world, despite the growth of IP signaling protocols.

What is the difference between SS7 and SIP? SS7 is a circuit-switched signaling protocol primarily for traditional telephone networks, while Session Initiation Protocol (SIP) is an application-layer protocol used for multimedia communication over IP networks. SS7 is older and designed for reliability in voice networks, whereas SIP is more flexible for voice, video, and messaging over the internet.

Can SS7 be used with 5G networks? SS7 can interface with 5G networks through gateway solutions that translate between SS7 and IP-based signaling protocols like Diameter or HTTP/2. This interoperability is essential for supporting legacy services and ensuring smooth transition to 5G, particularly for roaming and interconnection with older networks.
