Asterisk only moves to the fax extension if it detects CNG tones. Some
fax machines send it, some don't. You may want to listen to the fax
machine as it's sending. If it starts with a tone immediately after
dialling, before the remote side has a chance to answer (or even ring),
that's a CNG tone. If you hear nothing, then the sending fax isn't
sending the tone (so there's no way for Asterisk to detect the fax).
