Caller: Not sure

Long delay after answering (overseas / autodialier)
Caller requested my previous name that I haven't used in many years.

Likely spam.

The caller asked if I was ... My shorter name, I murmur in positive, and then she said thank you for your time and hung up. Very weird, now I will expect someone to address me by my name and say, who knows what? Most likely a scammer building their story
