This is not an answer to your question (sorry), but have you considered 
outfitting the panasonic with isdn lines instead? The KX-TD1232 work very 
well with isdn, as does asterisk.

As to your question I think there are several formats of analog answer 
supervision / disconnect supervision. I don't even think asterisk supports 
all of them. Do you know what methods are used by the KX-TD1232?
