Telefoniasüsteeme, also known as telephony systems, encompass the technologies and infrastructure used for transmitting voice communications over distances. At its core, telephony relies on converting sound waves into electrical signals, transmitting these signals, and then reconverting them back into sound at the receiving end. Historically, this was achieved through analog copper wires.

Modern telephony systems are largely digital. This digital conversion allows for higher fidelity, increased capacity, and integration with other data services. Public Switched Telephone Networks (PSTN) have been the backbone of traditional telephony, connecting landline phones globally. However, these are increasingly being replaced or supplemented by Voice over Internet Protocol (VoIP) systems.

VoIP technology transmits voice data as digital packets over the internet. This offers significant advantages, including lower costs, greater flexibility, and the ability to integrate voice with other internet-based applications like video conferencing and instant messaging. Business telephony systems often utilize private branch exchanges (PBX) or hosted cloud-based solutions to manage internal and external calls efficiently. Mobile telephony, using cellular networks, has revolutionized personal communication, allowing for voice calls from virtually anywhere. The evolution of telephony continues with advancements in mobile technology, network infrastructure, and the integration of artificial intelligence for enhanced call management and user experience.
