Hi,

 

I'm not a lawyer but it looks like that law is for carriers and not for you as an end user or administrator. So the carrier have to keep this data.

So I think this is not a roadblock for you. If it were a problem Microsoft as an American company using this solution themselves would have changed this and they would not have any Florida companies using Phone System.

 

But with that said more than 30 days data would be good in the Teams Admin Center.

I see that you started a uservoice request about this and that is the best way to go.
