1. Human operator: In the early days of telephony, calls were manually connected by human operators who used switchboards to connect the calling and called parties. The operators listened to the caller’s request and manually connected the call to the appropriate party.
2. Electro-mechanical relays: In the 1920s, the first automated switching systems were introduced. These used electro-mechanical relays to establish and disconnect calls. The relays would detect the pulses generated by the rotary dial, and then route the call to the correct destination.
3. In-band signaling: In the 1950s, in-band signaling was introduced. This involved using audio signals (such as touch-tones) to control the switching of calls.
4. Common Channel Signaling System No. 7 (CCS7): In the 1970s, CCS7 was introduced as a digital signaling system. This replaced the older in-band signaling methods and provided faster call setup times, better call control, and improved reliability.
5. Time switch: With the advent of time division switching in the 1980s, signaling was integrated with the switching function, allowing for more efficient use of network resources.
6. A space switch is a type of electronic switch used in telecommunications and data communications. It is a switching network that uses a matrix of crossbar switches to connect multiple input and output ports.

Today, signaling is largely based on digital protocols such as SS7, ISDN (Integrated Services Digital Network), and SIP. These protocols allow for more efficient and reliable call setup and control, and have enabled the development of advanced features such as call waiting, call forwarding, and conferencing.
