I currently have 2 phone numbers: 203-111-1234 and 203-222-5678. I would like to assign 203-111-1234 to a scout, but when I try to do this, I get an error message that the primary number must be assigned to a shared device.
My Question: How can I make 203-222-5678 my primary number so that 203-111-1234 can be assigned to the scout?
