[grc] Cell phone hybrid?

Some consoles are pairing with the phone over Bluetooth, which I imagine
would circumvent the security limitation, as should a hybrid using TRRS (of
which I haven't found an inexpensive one I like).

JK Audio's "Bluekeeper" seems to be an outboard bluetooth hybrid, and I've
generally had good luck with their products.

The big mystery is whether the phone sidetone is absent or can be turned
off, in which case TRRS adapters "should" work
