Repeated calls, no voice mail.  When I call back it rings many times, eventually someone picks up, but doesn't talk.

Call is from the Wellness Center PDX, which is a chiropractor and wellness clinic located in Portland. These are a great group of folks, and I just didn't recognize this number (they had never called me from this specific number before). The call was just to check up and see how I was doing, and if I needed to schedule an appointment in the upcoming months.
