This number has been calling my parents on a nightly basis for the past month at least. No message is ever left and when I call the number back no one picks up and there is no message board or anything it just rings.

I've been getting calls from this number on a nightly basis for the past month as well. Every time when I pick it up, no one is on the other end. When I call the number back there's an automated system stating it is the Pacific Fund Office and if I saw the message on caller id, one of the students in the call center must have called me. However, I highly doubt this is the case because they've been calling me around 8 pm or close to 9 pm and I don't think students callers from the Fund Office would be calling so late. There has been alternating numbers with the same caller id - all starting in 467 - calling my number and none of them have someone on the other line. Though, when I call all of those numbers back, it redirects me back to the automated system.

I have been getting calls from this phone number approximately 4 times a week.  No message was ever left.  I don't know the number, so I do not return the call.

If you are a former student or have contributed to the University of the Pacific then they will diligently try to contact you for more donations. Given that the students do call, and knowing the unorthodox schedule of a typical college student, I wouldn't be surprised if you received a call after typical business hours and/or on weekends. But they are like the blood bank-- after giving once, they hound you to keep on giving. I'm sure there is a way to request that your information be taken off the list as long as you speak to the right person.

I am also an Alumni of UOP.  This number sometimes call me at work (which would require them to go through a secretary to get to me,  so it is not a fully automated system).  Anyhow I am pretty sure it is Pacific Fund, haven't had talk to them thanks to caller ID!  I have requested that my name be removed from Pacific fund previously, but like someone else mentioned they are like the blood bank.
I wouldn't be surprised if they are not students and just a telemarketing company, I don't think UOP teaches telemarketing.  Would be sad that you have to go to college to learn to annoy people!
