This is the caller ID for the whole Rockyview Hospital in Calgary Alberta Canada.
Could be a loved one that's been in an accident - AND you can't call back unless you already know the direct dial-in number... and also includes public phones and pay phones inside the hospital!
So maybe answer it cuz it could be important!

Call from Rockyview Hospital confirming an appointment

i just got a missed call from this number and when i tried to call back, it says the Calgary Health Region...weird..

My husband works at the Rockyview hospital, and this is the number that shows up when he calls me. He told me that it is the number that shows up on the call display if a call is made from anywhere in that hospital.

I was phoned three times today by this number. The first two times I ignored it but the third time I picked it up and asked who was phoning and heard only silence and phones ringing on the other end before they hung up. No idea what that was all about but if they phone again maybe I'll get an answer.

Caller ID shows up as Rockyview General Hospital. Got 3 calls this evening with no message left. If I get another call I will pick up and listen to it.

got a call from this number today and a message from a lady saying that i am expected at the Rockyview hospital for a doctor's appointment (that i never made) with Dr.'s name mumbled uninteligibly. quite a nuisance.
