There is a new firmware 3 days ago at draytek ftp with released notes
ftp://ftp.draytek.com/Vigor2960/Firmware/v1.0.7.1/
As for telnet guide email the UK support, maybe can give you some basic commands also check why is not listed at their site ...

Checked today and manual still v1....

I have ordered a USB thermometer which appears to give me the temp but no idea on email or sms alerts as nothing in the manual. As said if you buy a product of this price you expect some back up!
