Hmm, my channel 1 is the FXO (i.e. connects to the wall socket) and 
channel 2 is FXS (that's where I plugged my phone line in)

Are you absolutely sure this is the right way round. I thought that an 
FXO module connected to the wall, and used FXS signalling. And vice 
versa.  My channel 1 is the one connected to PSTN so surely it should 
have FXS signalling?

Please excuse my ignorance, I don't mean to be telling you what to do, 
it's just that this is different to what I've read everywhere else. 
Also, when I try your settings, nothing works at all, I don't even get a 
dial tone on my analogue phone connected to channel 2
