Who called from 4803027258

My caller idea came up "University Co"  no answer when I answered the phone. I redualed the rumber, it rang, answered and hung up immediately.

that would be "redialed"

and...caller 'ID"...sorry about that

I keep receiving calls from 480-302-7258 with caller ID University of Colorado.  When I answer, there is a click.  When I try to dial the number I get a busy signal. I get these several times a week.
