Who called from 2692240570

Called my mobile. Two rings then they hung up.  They did not leave a voicemail.

Called my wife's phone, she missed the call, no voicemail.

Just got a call from this number. Hung up before I could answer

Same as all the rest. I didn't call back.

Rang once and then hung up before I could answer. Is the goal to get people to call back so it's technically the people doing the contacting and not the scam (I'm assuming it is)? Some sort of loophole? Idk, but that's the only logic I could come up with.
