Not on my cvs-head system that has been in use for over a year, and
updated to current cvs-head on a regular basis.

Used that same approach (until recently) for a fax pstn line. The
analog fax machine always answered the incoming calls, and zapata.conf
always pointed to a context that never did anything (not even a wait).
We still used that same analog pstn line for outgoing calls.

I think the key issue in this thread is the OP's wish to have some
external analog device answer incoming calls. When that external
device answers the incoming call, ringing disappears from asterisk's
perspective and asterisk treats it just like an abandoned call. If
the incoming call context doesn't have any statements to answer that
call, its not going to do anything with it. (In other words, the call
disappeared within a second or two after the first ring. Waiting 
around for another 10 to 60 seconds, or whatever, doesn't do anything 
useful.)
