Cloud Telephony
Cloud telephony is a communication service that delivers voice and telephony capabilities over the internet using cloud computing infrastructure, replacing traditional on-premises phone systems. It enables businesses to make and receive calls, manage voicemail, and access features like call routing, IVR, and conferencing through web-based interfaces or APIs. This technology leverages VoIP (Voice over Internet Protocol) to provide scalable, cost-effective, and flexible telecommunication solutions.
Developers should learn cloud telephony when building applications that require integrated voice communication, such as customer support systems, call centers, or automated messaging services, as it offers APIs for programmatic control and reduces infrastructure costs. It's particularly useful for startups and remote teams needing scalable solutions without hardware investments, and for adding telephony features to web or mobile apps via services like Twilio or Vonage.
