Push up hard on the bottom end, and it will come loose,

I pushed on it, but maybe not hard enough. I'll try harder tomorrow.

Exactly where were planning on splicing the DSL filter in?

This is an emergency phone in a residential elevator. Outside the
elevator is a switch box for the AC, but the phone line runs through
it too.


Or were you going to do
it where the wire feeds into the elevator shaft?

Yes, basically.

(In which case, an
inline surface-mount jack and screw-to-rj11 adapter would let you plug
the filter in.)

I'm not sure if there is enough room to get a surface-mount jack plate
in the switch box.

Having said that, that doesn't really look like a commercial-grade
elevator emergency phone

It is residential, not commercial.

somebody needs to call out on that phone, and they are the only one
there, it would suck if one of the other phones was off the hook.

It is on the same circuit as the other phones in the house.
