Who called from 3231548997

Rang twice, then hung up. Called back a minute later, received message that the number is disconnected.

I also got a call from this number. When I picked it up and asked who is calling, a male voice quickly said yes you can and then hung up!

Repeated calls received to purchase solar panels. We don't even own our home; but, they keep calling back.

Keeps calling me, finally picked up and they did not even say anything and just hung-up.
