[Asterisk-Users] Asterisk won't answer incoming analog line

[Lane]

I had to return my TDM11B because it put the PSTN line 'off hook' the moment I 
plugged it in and wouldn't hang it up.

The new card seems to work because I can actually make an outgoing call from  
the FXO port to my cell phone, so I'm pretty happy about that.

But Asterisk doesn't recognize incoming calls from the PSTN.  If I dial my 
home phone from my cell phone asterisk does not even recognize the ring.

Below is (I think) the relevant config files.  My question is:  How do I make 
asterisk recognize when the phone is ringing?

Thanks in advance
