Asterisk and Wildcard TDM800P Analog

estimates have a asterisk 1.4 with dadhi ,Wildcard TDM800P and Wildcard TDM400P (analog lines)

The problem that calls are showing the beginning of the ring as answer, even if the call is not answered, asterisk shows it as answered with analog lines, I tried even with polarity but still the problem.

Any suggestions?
