My iPhones ring together

Hello Apple Community.

Last September, I started working for a company and they issued me with a corporate iPhone 12 on a corporate plan. This was my first ever iPhone. I liked it so much that 2 months later I bought the iPhone 13 Pro Max on a two year plan as my own personal phone.

Both these phones are registered to my own Apple ID, but they have different numbers.

The inconvenience that I have is that when someone calls either of these devices, they ring together.

This is not practical. I want my customers and my colleagues to reach me on my corporate phone number and my friends and family on my personal phone number.

Is there a way to fix this?

Thanks
