Who called from 3056890000

It's an outgoing line from U. of Miami for any department calling through the central switchboard.

That's really weird.
I got that call too, and no answer, even when I called back. I tried *67 too.
The weird thing is that I get multiple "hang-up" calls with the number. This is not the only number.

Why does that happen?

It's probably from alumni to ask for your cuurent info or to get a donation. I've been getting the call for years, I stopped answering because I see the number.

Somebody pulled a April fools prank on me from this number. Thanks to the threads, I was able to suspect foul play ;-)

I actually got this call for my boss and when I asked what the call was regarding the person started laughing and hung up.  I think UM should start monitoring the people they have in their offices since this was truly a prank call and nothing more.
