Who called from 2137482411

I got this call 5 times on my IPod Touch. I have an app that makes my Itouch capable of making calls and sending texts. No one knows that I have this number. No message was left... They did call every two mins....

I just called the number and when it went through the answering thing said "thank you for callin California Hospital Medical Center" ?!?!?!?!?!?!?

The answering machine reply <California Hospital Medical Center>
They occasionally called to my iphone.
Do I have to report to DO NOT CALL?

Called me to tell me my father was in a bad car accident and needed surgery. You should probably answer.
