Businesses __must__ call from a registered business line. Caller ID should tell me who is properly calling. I won't answer it otherwise, and I really detest how frequent 'personal phone for business' is how places expect people to operate. At the very least they should have to bounce the call through a switchboard somewhere that rings me from the business line.
