Multiple Inbound Routes question

Hi, I have two DID’s plus my 1777xxxxxxx number from my provider. I’d like to configure one DID to ring a given ring-group and the other DID to ring a specific extension only. After reading some documentation, I have created three inbound routes: 1 for the 1777, plus the other two, but I have not been able to get it to work. If I omit the 1777 route, nothing works… I’m using FreePBX with AsteriskNow 1.6 – Any help would be greatly appreciated. Thanks in advance.
