You might need to have a greeting for the “main” route and one for the “nights” mode. VM Pro doesn’t really operate as you might intuitively think with the help documentation. You would think that the Night Fallback Group would go directly into that auto-attendant, but it doesn’t. So how do you do it?

First, you need to create two groups. The first group can be called Main and the second will be Nights. Next, make a new short code *800 where Feature: VM Collect and Telephone Number: #Nights. You will also create a virtual user called NightUser. A virtual user is nothing more than a user with no extension. Make this virtual user unconditional forward to *800 (the new short code).

For the Main group:

1. Make sure queuing if off
2. Make sure voicemail is on
3. The ring mode should be collective
4. Fallback for the night service will be the Nights group
5. Add your users that should ring in the office

For the Nights group:

1. Make sure queuing is off
2. Make sure vm is on
3. Ring mode has to be sequential
4. for all fallback groups
5. Add ONLY NightUser to this user list

Now, you can build 2 different auto-attendants. One for Main and one for Nights.
