It happened because you altered your terminal's baud (i.e. bit) rate and
neglected to save it to your Courier as well with AT&W.  What happens
is that when ATZ restores the modem's stored bit rate, it no longer
matches, and the incoming RING resonse is not displayed correctly (no RING,
no answer).

Most Courier owners eventually get caught out sooner or later, so don't
feel too bad about it.  As this anomaly is documented in the manual, it
also tells me that there's a lot to be said for suggesting that one needs
to RTFM.
