Hi.
Is there a specific reason you want to add notifications to every user? Without knowing more...
1. Would unified messaging (integration with Exchange/O365) be an option for you? This would cause all voicemail for a particular user to be delivered to email without setting notification options, and synchronizes message status between email and voicemail system.
2. If you do need to set notification devices for every user, the best way to do that would be in bulk import or update. You would need to set the following optional attributes in your import file or update these fields in an update file.
PhoneNumber_TextPager1 |
SmtpAddress_TextPager1 |
Active_TextPager1 |
(optional - see note) |
alias@domain.com |
1 |
Note: I use this field to indicate the callback number to access voicemail.
