sorry if there is a more relevant community. i tried on that other big forum site and was shot down by a bot and i am tired.

let's just say a person started working for a gig-type company, through an app, such as ****** and while "on the clock" and using the app, their iPhone was spontaneously, occasionally making 3-second OUTGOING calls to different numbers coded to San Francisco, where the not-so-hypothetical company is based.

and if you call the numbers back: "this number no longer works. please contact support"

what are they doing?
