It's an outgoing line at Beaumont hospital where they confirm appointments.

One of a few phone calls I got today with no message left, other  than my cell phone saying "Missed Call"

Called and tone sounds and then hang up 5 times in 15 min.  This is Beaumont hospitals.  Called from 248-435-4121, 248-435-7015,248-435-4668 and 248-435-4185.  I have had no contact with this company.  They are of no help on initial complaint.
