when i tried to observe the polarity reversal on my x101p (i only have this), it seems that my x101p does not care about polarity reversals but only battery interruption. my guess is that x101p is not capable of detecting polarity and i was thinking that a tdm card will solve my problem.
if you have a tdm400p maybe you can try to play with the answeronpolarity/hanguponpolarity in zapata.conf.
please tell me if my guess is correct that a tdm400p will solve this problem or else i'll be wasting money in buying a tdm400p.
thanks

This is a problem here too.. Is there any way to get the x101p/TDM400p
FXO ports to not disconnect when there is a polarity reversal or momentary
interruption of CO battery voltage on the PSTN line ?
