They want to forward all calls at night to the Messaging company?
Create a dummy user Extn 1234, set that user to unconditional FWD to the number you need (dialing 9 if need be). Also, enable hunt group forward.
Should be able to test, by calling 1234 from another extension.
Now create a dummy hunt group, call it night forward. Turn off Voicemail and any queuing and overflow. Make the only member in it, Extn 1234.
You can test, by calling that hunt group, which will ring the user, and use the FWD Unconditional.
Now, find out how your calls are ringing in. If they target a group, you can go into that groups Fallback tab, and set the Night Service Destination to the group you just created.
Finally you can go to any phone, and put a "Set Hunt Group Night Service". Can be on multiple phones, and when illuminated, is in night service...
An easier solution is if the calls go to a night attendant and there is an option to go to the after hours call center by pressing "0", you would just set the "0" to go to that Extn 1234 user, forwarded to the proper destination.
