Domains for Call queues and Auto Attendants. Can this be changed?

Looking to change the Call queues and Auto Attendants to a different sip address or with a different domain. I pre-built out a call workflow in skype for Business online with the Domain.onmicrosoft.com address, but it looks like that does not work really how I expected it to work.

Can you change this value without breaking everything? So far I have tried modifying this in Azure ad but that seem to break things.
