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

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??
