I suppose it depends on the phone, the network, which codec, and what kind
of noise cancelling was being used.
Just yesterday I was on my cell phone and the alarm tone from my UPS was
nice and loud to me, but the person on the other side couldn't hear it at
all.

Yes. I actually took a four conductor 3.5mm plug and tried all sorts of wiring
configurations. My cell phone tests for a load and switches its configuration
based on what it thinks is installed. This can be verified by a small icon on
the phone which appears when a handset or headset is

Normal headsets are TRRS.
Did you try with a TRRS connection?

I tried this exact setup more than six months ago and I could not get it to
work. Perhaps my novelty handset wasn't loud enough. My couplers work with a
land line phone just fine.
It's really cool to see someone who actually got it working. I'd be interested
in knowing the make of the handset.
I think for 110 and 300 BAUD it would be fine, where audio
frequency-shift keying was used. But any of the higher BAUD rates that
use PSK or QAM wouldn't make it past the audio/data compression used in
cell phones.

Interesting. I would have given that a low probability of working. Well if
that works you'd think a direct connect cable would be even better.
Opens up a whole new possibility for remote usage of Model Ts.
Does anyone know what would be needed for a direct to headphone jack
connection?
