API for making a call with a given text (SIP/IP-telephony)

Question

API

In WhatsApp and Viber, when registering, there is a function to report the activation code not by SMS, but by phone call.
The robot calls your number and dictates a digital code.

Do you know if there is a ready-made service that provides an API for
calling a specified number to play dynamic text?
At worst, you can synthesize the text into an audio stream yourself ( translate.google.com/translate_tts?ie=UTF-8&q=1%202%203%204&tl=ru&prev=input )
, but it is more difficult with a call.

Thank you.
