This is interesting indeed.  (I don't understand yet why you would
want to do that, run it from a WWW server, but that doesn't matter - it
really should work).

Looks like the message doesn't arrive at the shell script.  Maybe the WWW
server is doing weird things with its file descriptors?  You might want to
find out whether stdin/stdout/stderr are pointing to "somewhere" or
whether they are valid.

You might also want to try 1.1.20 - 1.1.14 is fairly old.

There is no way to send individual AT commands from voice shell, you would
have to configure the appropriate commands in voice.conf (or in the
source code, worst case).
