Hi,

I’m looking a way to make or buy an intercom system between room in the same house. That works more or less like a Walkie-talkie but wired on the local LAN .

With the following “requirements”

  • only voice
  • push to talk ( do not need to dial )
  • broadcast the voice too all receiver
  • AC-powered
  • work on the local Lan (Ethernet)

If you know any device that does that or a clever way to DIY or even an android app (LAN only)
I’m all ears. Thanks

    If WiFi would be OK, you could use an ESP32. It has an ADC and DAC that could be used for low quality audio and plenty of CPU power for simple audio codecs like u-law. You would have to write the firmware for it, but it’s not too complicated to capture, send and play some audio.
