Connecting the Vega 50 to FreePBX

I am attempting to configure my FreePBX Appliance to communicate with the Vega 50 (8 fxo) .

I have followed the pages located at
http://wiki.sangoma.com/Vega-analog-configuration-analog-lines-to-ippbx
and
http://wiki.sangoma.com/Vega-analog-BRI-configuration-trixbox-fxo

Currently,
Incoming calls have a caller ID of “Reg and AuthID” however when I answer the call there is no audio and the caller’s phone keeps ringing.

Outgoing calls fail with a “Buzy” signal beep

Is there somewhere else I can get configuration examples to get this working??
