Untrue.

If the context that the FXO port is dumped in to lacks an extension that would 
answer a ringing line, it won't answer.  

Create an extension like thus:

[noanswer]

(that's it, nothing in it) -- now point zapata.conf to it:

context=noanswer
channel => 1  (or whatever channel it happens to be)

reload asterisk, that is it.
