Caller name: Inmate Call
Caller type: Unknown
The same person has called on 2 separate occasion missed if they gave name. "Hey, wow, glad I was finally able to reach you. You're harder to reach than the peak of Mount Everest!" First call some sort of catchy ditty like that as well.
The first time I asked him why it came up on my caller ID as "Inmate Call" and they acted all surprised and said "I have no idea why that would happen, let me have you talk to my supervisor..." The line went dead.
The second time, again, I missed if he identified himself. I said, "Hey, you've called me before and asked you why it came up on my caller ID as 'Inmate Call' and you were putting me through to your supervisor. You had another witty remark about being able to reach me like this time. I never did talk to your supervisor." CLICK!
