These calls actually come from the UCF Foundation Office not the UCF Alumni Association. The caller ID just says UCF Alumni, but they are not making the calls.
I got a call from this number yesterday (a sunday) at 6 PM. I answered the call and they did claim to be UCL Alumni and wanted a $250 donation for some program. I asked if they have a website so I could go check out what this program is and make a donation amount of my choice online but they said they would prefer me to make the payment at that moment and over the phone. That got me suspicious and I told them I was driving and I will call them back on that number but they didn't want me to since their office is apparently not taking calls at the moment and offered to call me back another day.
This number called 16:06 Sunday, 2/8/2015, and left no message.
I did not attend nor graduated from UCF, but I do have two children there.
But there is no way in he)) they have this number as this is my work phone for which they have no record.
