I understand that you need clarification on Microsoft teams licensing for phone.
Microsoft Business Premium license gives you Teams functionality which is fine
Microsoft Teams Phone Standard license gives you access to the calling functionality in Teams which is fine
You can buy and assign different Calling Plans to different users, depending on the needs of your organization.

In summary, all the license you just mentioned are good to make use of the teams phone callinf functionalty
