How to program voicemail prefix, night service,multiple-line appearance on BE3K?

Question

Hi All,
A few questions about BE3K as below : 
1.    What’s the default prefix  for voicemail  in BE3K ?  or how to program prefix for voicemail in BE3K ?
In UC500, we can manually program  a prefix number or code  such as “6”  , then dial "6" + extension to access to that extensions' voicemail  from any subscribed phone. We often use this "voicemail code + extension"  as night switch VM.
2.    How to program night service/schedule in BE3K?
          I understand there is  day/night service on Auto Attendant setting what if customer dosen't  want caller to hear any AA greeting or option 1, 2, 3 , most of  customers just simply want to caller reach a hunt group during the day and a voicemail greeting during the night ( again, how to program night switch VM?)
3.    How to program multiple - line appearance on BE3K ?
You are more than welcomed to give answers or point me to right direction 

Answer 1

Billy,
On 3....
A user can "own" multiple lines. These are provisioned on the user page. (Note that this is not required to have multiple lines on a phone, but is a way to assign multiple lines to a user if that is desired when sharing lines on a phone.)
One the phone configuration page, just keep adding more lines to the phone in the "extensions" area.
When adding more lines to a phone, if you enter the same extension multiple times, then the phone enters a "roll-over" mode. In this mode, each line (of the same extension) will only allow one call. The next call then appears on the next line on the phone of that extension. Some customers prefer this mode of behavior.
When using roll-over mode, be sure to take into account any other phone that shares that extension. You'll want both phones to be in roll-over mode. If one phone is in multi-call mode for that extension (the extension appears on the phone only once), and another phone has the same extension in roll-over mode (the extension appears more on the phone more than once), then while both phones will ring with the first call, only the first phone (mult-call mode) will ring if a second simultaneous call arrives. This is because in roll-over mode, the second phone cannot handel the second call, and wants to forward it to the next line appearance. However, the first phone (multi-call mode) can handle the call on that line. So, the second call is offered to that phone without forwarding to the next line appearance.
If you want to mix these two modes, configure two phones with the same line (shared line) and setup the two phones differently, one in roll-over mode, and the other with just one line appearance. Then, use other phones to call that extension so that you can experiance the behavior first hand. It can be a bit confusing to get a problem report from one of your end users because of this missconfiguration. Seeing it first hand will help you recognize if you ever accidentally enter this configuration. This missconfiguration cannot be prevented as you pass through it when assigning lines to phones. However, the GUI does not warn you that you are in this configuration.
