Telephony Systems

Telephony systems refer to technologies and infrastructure that enable voice communication over distances. Traditional telephony involves landline phones connected by wires, utilizing circuits to transmit calls. Modern telephony includes mobile phones and Voice over Internet Protocol (VoIP), which use digital signals over the internet. These systems work through a network of switches and servers that connect callers, whether through traditional phone lines or internet connections. Telephony has evolved significantly, allowing for seamless communication across the globe, supporting not only voice but also multimedia messaging and video calls.
