When we moved from our old phone system to RingCentral, we had many organizations who would call in, and their phone number and business name would show up. I'm not really sure how this worked, but there must have been some kind of directory that could grab the company name. In RingCentral, we have yet to see any company name show up on inbound calls; they all just show as "Unknown."
It would see like our Incoming Call Information is set to allow for company names to come through. Perhaps the RingCentral Caller ID database is just very limited.
