As above. Call from 617-300-2000 but no message or response. Caller ID said only "Massachusetts", which sets of my personal scam alarm. Google search indicates this is the number for WGBH public radio and TV but I doubt they'd hide their identity in the caller ID. It's possible this number is being spoofed by someone else - telemarketer/scammer/collection agency or any of numerous other disreputable types. Blocked the number on my phone.
