A voice API is a tool that software developers use to create and get phone calls using an Application Programming Interface (API). A voice API connects internet-based applications to the Public Switched Telephone Network (PSTN).
One of the main benefits of a voice API is that creators don’t need telecoms proficiency to build voice applications. The voice API performs all the telephony functions, so developers can focus on designing an attractive customer experience. Voice APIs are also extremely configurable, simply consumable, scalable and extremely cost effective.
