Actual automatic dialing of the base of numbers with IVR?

Question

SIP

Hello. Tell me, is it relevant today to use free auto-dialer systems like:
www.ictdialer.org/content/installation-guide
www.goautodial.org
www.newfies-dialer.org
Or freePBX, etc.
Which of these generally works and is supported today?
What VoIP providers can be used for auto-dialing to multiple streams?
The following action is required: Automatic dialing of the base of phones in several streams, playing the record, waiting for a keystroke, and performing an action with playing the second record. Simple questionnaire. What is the best way to do this with a minimum of cost and effort?
Thank you.
