This is a generic ucla number that will appear on your caller id whenever someone on the ucla campus calls you. Basically someone with your number has attempted to contact you from ucla's network.
I received a missed call from this number today. Appears to be a random mistake from someone dialing out from the UCLA campus. I called back and got the answering machine for UCLA. I don't know anyone at UCLA so it's no wonder they didn't leave a message! I wonder how many mis-dailed phone numbers occur every day? Now there's a search question!
