asterisk users - Apr 2005 - Problems getting FXO channel working - Unable to create channel of type 'Zap' (cause 0)

Hi, I have searched around as much as I can and can't find any good info to
help me try this problem. I have added a FXO card to my server and from
everything I can see, I have configured it right. *Obviously not*

Below is my config, any ideas on troubleshooting this ?

regards

Mark
