FRITZ!Box Calllist

FRITZ!Box Calllist is a custom integration that builds a call history and live call state from an existing FRITZ!Box call monitor sensor. It tracks ringing, dialing and active calls, keeps a persistent history, and records call duration for live and completed calls. It also detects the FRITZ!Box answering machine from the connected device. Optional reverse lookup of unknown numbers uses switches for each provider, which are disabled by default, and results are cached locally in Home Assistant storage. Options let the call monitor sensor be changed later, manage the lookup cache, and choose whether outgoing calls are shown. It works locally, is set up in the UI, and a separate Lovelace card can display the call list.
