Join Table help

I have 3 tables in my Quickbase App,

Assignments (PhoneNum is key),

Member (PhoneNum_MbrID is key but has PhoneNum field),

Calls (Record Id is key but has PhoneNum)

Assignments is connected to Member (one to many)

Assignments is connected to Calls (one to many)

I have to create a table report from Calls table and pull all member table data. How can I achieve this? Please help.
