Thanks for the tip. The script now waits 10s and it's long enough for
Zaptel to hang up the original call.

The next step is checking that the remote party has actually gone
off-hook before playing a message.

I tried WaitForSilence() in extensions.conf and "callprogress=yes" +
"progzone=fr"  in zapata.conf, but that doesn't work (when my
cellphone goes off-hook, Asterisk remains silent, and tries calling
again after I hang up).

Does it mean that there's no way for Zaptel to know the status of a
call (ring, answered, busy, etc.), and the only way is to use Wait()
and hope for the best?

Thank you.
