Service for notifying customers with a call with dynamic text?

Question

VoIP

Hello, the task is this - we need a service to notify customers about the receipt of new orders by phone call, while the text is dynamic, not templated. What service would you recommend for this purpose? Services that I saw - first a template is created, a list of numbers is indicated, and so on, too many gestures.
