Thanks for your answer, the problem was fixed in a %50, first, i cleaned the contacts of the board, and it works just like you said, but with a RJ14 connector using the RJ11 standard, but this board, support 12 lines in 6 ports,2 lines by port and only works 6 lines.
Which line uses 2 pins of the rj14 connector, line 1 use pin 3 and 4, line 2 uses pin 2 and 5.
Only works pins 3 and 4 in each port, and i dont know why.
Thanks.
