Who called from 8783324001

Got a call.  They asked for Gary.  I'm not him.  They said "sorry" and hung up.  Female voice.  She was talking to someone when I answered.  May be a legit misdial.

Called several times until i picked up and then hung up

Got call from this number many times, never picked up.No message was left on answering machine

They called twice within seconds.  2nd time left voicemail using my name saying they had to reschedule my physical for later on this morning with "Dr. Shoes".  I did not have a physical schedule nor do I have a doctor named "Dr. Shoes"....
I did not answer.  I did not call back..

This is the number that shows up when called by my doctor located in the Wexford Health & Wellness Pavilion of the Allegheny Health Network. 100% legitimate.
