Simulate many endpoint registrations

Hi can you suggest a way (scripts, containers, softwares) to simulate many registrations at a time againt asterisk server?
Let’s say something similar to sipp to simulate many calls, I would like to do it with registrations.

Any help would be appreciated.
Regards

You can still use sipp.

I was searching right for it. It’s possibile .
Sorry for dummy question.
i will use it.
Thank you
