Who called from 3145778000

I got a call from 3145778000 at 1:53 am. when i called back it was the switchboard at SLU Hospital.
This was not the first time.

We received 3 calls last night from this number.  One time they left a message which could not be understood.  The 3rd time we answered and still could not understand the caller.  Next time we will report the call.

I got a call from that number at 1:14 this morning

Just got a call from this same number at my work number. The caller left at my voicemail a difficult to understand and that made no sense to me at all. So that's why I reported it here.

This number has called me 4 times on 4 seperate days within a week. No voicemails have been left and the calls always come when I am at work or asleep.
