Who called from 2048370321

A few days ago I got a call from this number. Who?

everytime i answer this number they hang up on me but when my bf answers it they talk to him why is that when this my huse their callin.

It's the Grace Hospital Emergency Department in Winnipeg, Manitoba.

I got one, too, and when I called back it said "we have tried unsuccessfully to reach you. This is a recording". Anyone have any idea who this is?!

I too received a telephone call from this number. I wasn't at home but I have call display and I tried to return the call twice, and each time I heard an answering machine kick in with the same responce."We have tired unsuccessfully to reach you. This is a recording" Who are they and what is this about? Does anyone know?
