Whereas you can use a normal telephone with Inspiration/Revelation PABXes using the voice circuit on terminals 2 and 5 of the four-wire output, the featurephones require the additional data pair on 1 and 6 to work correctly.

I'm not sure whether even the voice circuit works on a featurephone without the data pair connected.
