How to switch between day and night mode?

The steps to delete auto attendant messages, including day/night mode, opening inbox, schedule 1, schedule 1 intervals A/B/C, will depend on the specific phone system or software you are using. However, here are some general steps you can follow: Access the auto attendant menu: This is usually done by dialing a specific extension or accessing the system through a web-based portal. Navigate to the message management section: This section may be labeled "Greetings," "Prompts," or "Recordings," depending on your system. Select the message you want to delete: This may involve listening to the message or selecting it from a list. Choose the delete option: This may involve pressing a button or selecting a menu option. Confirm the deletion: Some systems may require you to confirm the deletion before it is finalized. Repeat for all auto attendant messages you want to delete. It's important to note that deleting auto attendant messages may affect the functionality of your phone system

This is a function of WHATEVER voicemail package you have. We are technicians here NOT mind readers.

I'm going to guess you have a TVA voicemail. You need proprietary software to access it as well as the password.
It all depends on how it was set up. Do you manually toggle day/night or is it done by the clock?

(MOST LIKELY) way to fix this for you.
Once in go to services expand the boxes and you should see company greeting and the number of the CO greeting to use for day and further below for night. Make them both 1.

Night feature at reception set or set that you put night service on go Feature #87. For delete of mailbox Feature 983 enter password which should be 1020000 if 3 digit extension numbers or 120000 if 2 digit extensions. Then press mbox then del enter extension number then press del.

This depends what voicemail you have, SVM OR TVM. and you need to know what group rings in each mode SVM day *47 (voicemail extension number) (PIN number) *38801 record STORE NIGHT *47 (voicemail extension number) (PIN number) *38811 record STORE TVM voicemail extension number (500 or 200) #6* (ringing group number) option 3 then 1 then 1 follow the prompts

Press the SPK (Speaker) key then enter the appropriate service code...
Service Code
818 + 1 Activating Day 1 Mode
818 + 2 Activating Night 1 Mode
818 + 3 Activating Midnight 1 Mode
818 + 4 Activating Rest 1 Mode
818 + 5 Activating Day 2 Mode
818 + 6 Activating Night 2 Mode
818 + 7 Activating Midnight 2 Mode
818 + 8 Activating Rest 2 Mode

If you are using an Active Voice product (typical w/ NEC) you need to change the hours of operation on the voice mail system. "Night Mode" only changes the ringing characteristics of the phone system and where calls ring, not the greetings that play on the voice mail. The voice mail plays a particular greeting (Day/Night/Holiday) based on the time of day specified in the schedule. The system administrator for the voice mail would have to make this change.

It's only that simple if you have a guide to what Custom Service or greeting plays now. When the system moves from Day to Night mode, the installer assigns a menu that plays. You can change it if you know which one. If you don't get the right one, there would be 98 other custom service and 31 other Company messages that you could record to and they'll never play.

try by going thru the clock settings it should be found there only

You have 4 different modes of calling available to be programmed: DAY NIGHT BREAK and LUNCH. Your installer has to set up the ICD groups, but you can create a LUNCH group which looks like the day mode but rings all phones. The codes are accessed by dialing on the intercom *780x where 0 is day 1 is night 2 is lunch and 3 is break.

You may use the NIGHT mode in the daytime, but if you have voice mail, it will play the night greeting instead of a day greeting.

Ok. You will have to find someone who has access to system manager, or has system manager rights for their mailbox.

They will then be able to select System Manager Options, then Change the Greetings. It will tell you which mode you are in, and ask you if you want to change to Holiday Mode. The responses are 1 for YES and 2 for NO. Say no to Holiday Mode, and then it will go thru Day Mode and then Night Mode, playing each one first then asking if you want to change it.

If you must call in a service order with your phone system vendor, make sure he/she not only assigns someone's box with manager access, but also creates a back-door box with manager access. This way you won't be messing with the original Manager Box. It gets expensive having NEC decipher the Manager's password if it gets changed and no one remembers it.
