Auto Call
The card has a autocall feature, that will call a extension right after it loads and registers. You can combine this with actionable notifications from Home Assistant and parking to create a one-click setup to accept incoming calls.
Usage
Add ?call=<number>
to your URL.
Example:
https://my-ha.duckdns.org/phone-lovelace?call=555
This will call 555
when the card registers. In the add-on, 555
is preconfigured to pickup a parked call.
