Are you sure you're using the correct cable to plug the FXO into the POTS?

It sounds to me like maybe you've got a crossed cable where you need a 
straight one, or vice versa - there are certainly plenty of variations in 
cables from different vendors, for different bits of equipment, in different 
countries, so maybe you just need to try another one?

There should basically only be two types - line signals on pins 1-4, or on 
2-3, so there shouldn't be too much to test...

Hope this helps,

Antony.
