What are these outgoing calls on my call detail

[roman hernandez]

I am hoping someone will be able to answer this question for me, as metro has never been able to give me an accurate answer. I realize the call detail is fro 2010. I see on my call detail where voicemail was called and checked. But, in mid Oct 2010, I started seenig calls made to various different 714 area code numbers, None of these numbers were a true persons phone, it rang more like a fax machine or payphone, Each call is followed by an incoming call and for around the same duration in length. The phone was an older flip phone and I have copied and pasted an example of the call logs below, as well as shared the link of the entire call log

Hello there!
Albeit I don't have an answer but, are you comfy with all those phone numbers displayed like that?? Just concerned about some spambots picking up on this thread and having a field day with the phone numbers, ya know?

Do you have any call blocking apps or features enabled?
Apps like "nomorobo" initiate logs like this to enable them to block spam/robo calls.

So this is a call log from seven years ago, using a flip-phone? Do you remember what you were doing then, who you might have been calling?
