I did lots of research, however I didn’t find any scripts and tools to get the information about who last login the common area phone. We could use the Get-CsCommonAreaPhone cmdlet view information about the common area phones configured for use.
In addition, I find a tool which could let you find the current information about your common area phone, you could refer to the following link to get the tool:

Hope any one in our forum can share the experience when encountering this kind of issue.
Best Regards,
Evan
