A smart home with a phone call, possible?

hi friends
I am looking for information on whether it is possible to control my private home with a phone call “and not with the application” do you have any information on how this is possible?
Thank you very much

There are several examples on HA being controlled with Voice Assistant over a SIP phone.
You might have to rig up a phone central like Asterix if you need to actually deal up that Voice Assistant service from outside.
