Phone calls.
- The Show is a speakerphone: it signs in to your own SIP provider (tested with VoIP.ms) over TLS with SRTP and places the calls Home Assistant asks for, including by voice ("call Alex").
- Incoming calls take the screen with Answer and Decline, light a dark screen, and show who is calling; Hang up while a call is up.
- Calls between your own TECHO5 devices, and announcements into a call in progress, for a help call that alerts your phones and tells whoever answers what it is about.
- Home Assistant gets a Phone sensor, Answer and Hang up buttons, phone_call / phone_answer / phone_hangup actions and an esphome.techo5_phone event for each step of a call.
- Off until you sign the Show in with the phone_account action. Setup and example automations: docs/phone.md
Not an emergency phone: set automations up to call people. The boot image is unchanged from v0.2.10.
Root filesystem removed: it included LineageOS's vendor files (device drivers and firmware), which aren't ours to distribute. Install v0.4.1 or later instead: devices keep their own vendor files from then on.
