Is is call 'Night Transferred'. This says it is done with a button. The manuals are dreadful! I can't find anything 'timed'.

It means there's "No Such Station" :-)

VM extensions are part of the system, usually the pilot number is the lowest of the sequence. If your button got reprogrammed and you're dialing a number that doesn't exist, you'll get that error.
Start by dialing like 22, 23, 24, 25 (4 highest ports in a 0816 DSU). Reprogram the button by Intercom **1 press the button and dial 6xx where xx is the VM pilot number.

Sure. #4 picks up the extension if it's ringing in your group, *4 + ext is directed. It's in a manual on page 18 http://www.wedophones.com/Manuals/comdial/DSU%20and%20DSU%20II/DSU%20II%20Non%20LCD%20Speakerphone.pdf

Your DSU/CUS can set clocking/timing from the local central office (CO) or internal.
There are MANY external DSU/CSU in the market.
Example: Adtran and Lucent


Please reply with what type of T1 DSU/CSU is connected to your unit.
==== If your setup does not use an external DSU/CSU then look for setting for your internal T1 card.

Are all cards on the same rack?
Grounded?

Try two things. Ensure the system has set this phone up for handfree activation.

lastly, if you can not hear a dial tone through the handfree unit then you may have a bad speaker

Unfortunately if the problem started after a lightning storm the modem is almost certainly fried. I used to work at the UK's largest IT support call centre, we used to check the weather reports every morning because if there had been a lightning storm anywhere in the country we'd get a slew of calls from that region from people who could no longer connect to the web. Phone-lines collect a large static charge during a storm and are unprotected. I'd strongly suggest you contact the supplier regarding replacement.
