Klingel

FIXME

Projekte SIP-Türklingel in „Ritto Minivox“-Gehäuse

Wenn die Klingel zickt, den AP beim Oszilloskop powercyclen.

Hardware

• Ritto Minivox-Gehäuse
• WRTnode
• USB-Soundkarte (vgl.)
• Strombezug über vorhandene Klingelinstallation, in der Hauptverteilung im EG die Sicherung B3.
  • Gleichrichter → Fette Elkos → Step-Down mit LM2576

Software

• baresip
  • Module: cons.so, g711.so, alsa.so, uuid.so (tmp), account.so (tmp), contact.so, menu.so
    • cons_listen 127.0.0.1:5555
• /etc/rc.button/reset
