What service can be used to automatically call customers?

Question

SIP

Hello,
maybe someone has come across such a task: you need to call clients from the list, read the message (Text to Speech) and find out if the client clicked 1 or 2 (ideally, he said yes or no, as it happens in IVR of some banks). Perhaps someone can suggest a proven service with which you can perform such a call?

Answer 1

service no, asterisk yes

Answer 2

The question is not clear. Are you interested in companies that can provide this service? Or the means by which the result can be achieved?
If the means, then this task can be performed by many call centers. For example, implemented on asterisk or Solidus.
