Who called from 9798712472

Call comes to one of our office lines.  ID shows as Unavailable.  When I answer, there is no sound and after a few seconds we are disconnected.  Has happened several times.  Today after it happened, I called Unavailable and this number showed up on the phone screen.  A recording states, "No One is available to take your call at this time.  If you received this call" then the recording disconnects.  I called it back a 2nd time to see if message played further, but the same.

979 is a valid area code - but 871 is not a valid exchange in that area code - caller ID reads "TEXAS" - no message left - now blocked

Caller ID says Texas. I do not answer. No message left.
