A caller says they couldn't get through

Check that call forwarding is still active on your business phone. Some carriers drop it after a network change or an outage, and it fails silently.

Dial *72 followed by your Clayta number to reinstate it, then use Settings → Test call to confirm the line answers.

This is the cause the overwhelming majority of the time. If a test call works and a real caller still can't get through, tell us the number they called from and roughly when.
