A call didn't ring through — why?

Almost always this is a call-forwarding issue on the carrier side. Try these in order:

1. Open the line in the app and check its status. If it shows Broken, forwarding isn't active.
2. Have your parent re-dial the forwarding code we show for their carrier, then place a test call from a phone that isn't in their contacts.
3. If it still won't verify, the carrier may have dropped the setting after a plan or SIM change — re-run setup for that line.
4. Need calls to ring normally while you sort it out? Toggle Pause screening on the line; calls ring straight through until you turn it back on.

If a specific real caller keeps getting screened, add them as a trusted contact so they ring through next time.
