Who called from 4582011212

Number calls but nobody is there,  telemarketing robot I assume.

Very weird.  Female voice, says her name is Carol, long pauses, then ''hello?"

Call back and press 8 to be removed from their list.

I learned a long time ago that pressing buttons simply increases the amount of calls received.

They call my cell phone and say nothing. This is the second time, the first was about 6 weeks ago. I can't find any information on the number. The zip code listed on whocalled.us says 54321 which, according to my google search, is a non existent zip code. When I look up the area code it says Oregon. Anyone have any clues?
