@Michael ok, how does such a setup specifically looks like or which components are used?
@AVI The CID will be sent consistently.
I still have the open question:
How to monitor/log and automate test calls?
Which software or setup could be used for that?
Which software, setup can detect if a targeted phone (Landline/Voip) is ringing and hangs off automatically?
I also would be glad to get some keywords for this topic, because my own research only let me find commercial providers.
