Who called from 4014271001

I got two calls from this number within a couple of minutes. There was no answer on the other end, and it sounded like an echo of my own voice as I kept saying hello.  I didn't answer the phone the second time.

I got one call from this number, try calling the number back, a machine said that this phone number is not longer in service.

i got a call from this number and i called back it said it was no longer in service even though they called me a minute before

These numbers are from Life Span Medical Group from either Roger Williams Hospital in Providence RI or Land Mark Hospital in Woonsoocket RI

In my case, the caller said she was from Miriam Hospital in Providence, also part of the Lifespan Medical Group. She had my name and the name of a patient already, so the caller was highly credible.
