Bogus caller.
Two calls in rapid succession.
When I answered, there was a pause, then a robo-call sound and disconnect.
A couple weeks earlier, I had a similar call from a suspiciously similar phone number.
Either a outright scammer or an unscrupulous telemarketer.
Robocall for burial insurance.
Automated voice 'Maria from Senior Benefits' - launched into a pitch for 'final arrangement' insurance.
When given a chance to answer a question, I asked to be removed from their call list.
Voice said said something like 'alright, goodbye' and disconnected. We will see if they keep calling.
