Found number on caller ID

I received a call at 5:53 Central Daylight Saving Time from this number. When I answered there was silence for a moment then a female voice saying "Goodbye".  Who or what the heck is "Dorothy Beach"??

Answer it and a recording says Goodbye

They called twice and were trying to get my Windows ID number off me.  Said they were from Microsoft and my computer might be infected so I should give them my Windows ID number so they could check!!!    Man has an accent.   First time I hung up...next day told them it was bull & reporting them to RCMP anti-fraud squad.

They call my parents at least once a week, for almost a year now. Guy with thick accent says he's "from Microsoft and their computer is infected", and he needs Windows ID number to check... However, he just changed his strategy, now saying "does your Windows ID # start with 888".

The whole thing is so stupid its hilarious, as my parents do not even own a computer, and that's what they say everytime. They have caller ID, I don't know why they pick up the phone.
