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
