AsteriskNOW + Panasonic KX-TDA200

I have problem with connecting AsteriskNOW with Panasonic KX-TDA200.
Panasonic has 16 channels VoIP Card (KX-TD0490). I tried to make SIP tunnel between KX-TD0490 card and AsteriskNOW but it dosen’t work. Please can anybody help me with this problem. May be somebody has done such a think and it will be grade if you will send me FreePBX configuration screenshots or Asterisk .conf files.
