I find it odd that there are essentially *zero* good and affordable solutions for push-to-talk systems. Everyone just accepts crappy FRS quality since there's not really anything better available.
It would be amazing to have a simple dedicated device with a speaker, mic, 3.5mm port, a tiny display and menu button, and a push-to-talk key.
It could come out of the box preprogrammed with a few ESP-NOW based channels, and then allow you to add RTP multicast paging on a proper WiFi network(Which seems to be what the expensive SIP phones use).
The ESP32 can handle Opus compression, so there should be enough bandwidth for a few repeater hops.
If it was 18650 powered it should be able to last all day, so you could just leave a few around as repeaters, one hop is probably enough for 90% of things FRS is actually good for.
The same hardware could also connect to a smart voice assistant server, act as a wireless media streaming target, or be a wireless doorbell beeper for home assistant.
I've seen a bunch of projects like this, but nothing available as a mass produced, ready to use device.
