A voice API is used to dial and receives phone calls by connecting through internet-based applications to the PSTN (Public Switched Telephone Network).

The main benefit of a voice API for developers is that they won’t need the telecoms expertise to build voice applications. The voice chat API will execute all the telephonic functions, so that the developers can concentrate on cultivating an engaging customer experience. Voice call APIs are also highly configurable, scalable easily, consumable, and extremely cost effective as well.

Voice chat API for developers can also be used to route voice calls with global connections through phones, mobile applications, browsers, and SIP domains.
