Telephony
Telephony refers to the technology and infrastructure for transmitting voice, data, and multimedia communications over long distances, traditionally via telephone networks. It encompasses both legacy systems like Public Switched Telephone Networks (PSTN) and modern internet-based solutions such as Voice over IP (VoIP). In software development, telephony involves integrating communication features into applications, enabling functionalities like voice calls, SMS, and video conferencing.
Developers should learn telephony to build applications that require real-time communication features, such as customer support systems, collaboration tools, or IoT devices with voice capabilities. It is essential for industries like telecommunications, healthcare (telemedicine), and finance (call centers), where integrating voice, messaging, or video into software can enhance user engagement and operational efficiency. Understanding telephony APIs and protocols allows developers to create scalable, secure communication solutions.
