[poplar1]

Which model(s) of the X-link provide reverse battery supervision?

[Stan S]

All of them, after that function is programmed.

I have been able to reverse polarity by programming, but not as an action when party answers. If that is an option, I would be happy to learn about it.

Under 'Advanced' check the box that says 'Line Reversal'.
Line reversal is different than Reverse Tip And Ring.
If you checked 'Line Reversal' there is still no guarantee it will work.
Transmission of Line Reversal (supervision) is a function of your cellular system.
They tell you that when you check that box.
