You could look into using esp32's for it. There's variants with copper ethernet and people have used them before to both act as voice assistant mics and to play back audio with Home Assistant. Real time stream audio reproduction might be too much for them but it's worth a spelunk if anyone has already gotten close enough.

Two VoIP phones setup to hotline dial each other's IP address and auto answer on speaker?
A bit more information about what you're trying to achieve would be helpful.
I've tried few android apps but none does what it claim
- WiFi Walkie Talkie different channel on device, with no way to change them, voice do not pass.
- two-way-walkie-talkie, voice do not transmit, and anyway not open-source apps
- Zello PTT Walkie Talkie, do not work on LAN, not open-source.
Are you looking for two way audio? Or just transmitter to receivers only?
