EVERY TIME somebody attempts this yet again; 2 oldskool phones and a 9v battery! thats it, thats the whole thing!
So I never even saw the page this post is about, but somehow I can just feel that it somehow involves an overkill of brand-new digital electronics.
Like; is there a raspberryPI involved? cause I bet theres a RaspberryPI involved.
2 oldskool phones and 1 9v battery. AKA "telecom".
I for one, have created one using Mumble on raspberry, and works even better that OP's solution. I have it running on my computer, and I can mute/unmute with a mouse click. Works for me.
Yes, a RaspberryPI is a "Computer" or "Universal Machine". So literally every ACTUAL SMARTPHONE (regardless of price or ability) is a "Better Solution" than this.
a RaspberryPI for this purpose is such a waste!
"But Think Of The Children!" you cry!?
So now we're teaching the kids that the way to build a house is to buy a skyscraper and burn down the top floors? Seems like this has been goin on since the "S.T.E.M." fad and its pretty easy to see the effects if you stand back far enough.
you can run a RaspberryPI off a 9v battery too, just not for very long.
