Dial in possible?

Hello

I am runing the docker image with Jitsi and Jigasi. I can invite telephony users. But is it also possible that users can dial in via phone by themself, just by calling a kind of dial-in number?

If yes, where is a working guide for this?

Kind regards

Is this really not possible? Any idea or manual?
