I wonder how to teach CRM to call back numbers and check whether they picked up the phone or not?
Subject,
there is a CRM. There are companies in the database, companies have numbers. There is an idea for which it is necessary to somehow understand whether the phone was picked up when dialing or not in N-seconds.
I would appreciate any ideas or advice.

Answer 1

It’s a little unclear what kind of CRM we are talking about, and what software the call provides.
If you need to develop such functionality, then take Asterisk as a telephony server and interact with it from PHP using the AMI interface. For PHP there is a phpagi library phpagi.sourceforge.net

Answer 2

I hope this company does not know my number)

Answer 3

Those. Email spam isn't enough, do we want more phone spam?

Answer 4

telephony protocol signaling is responsible for this.
She will tell you for sure whether there was a connection or not.

Answer 5

By response from the telephony server. After integrating said server with CRM, of course.

Answer 6

Yes, you can. But why? You can check whether they are active or not in other ways. And it is not clear why this is needed in CRM.
