VIP User Services enables you to send security codes directly to a user's mobile device by using SMS (Short Message Service) or voice calls.
Steps as follow:
In AD:
- Ensure that the user's telephone numbers have been provisioned for the user
- for SMS OTP, the attribute needed is either mobile, othermobile, or mobiletelephonenumber
- for Voice OTP, the attribute needed is either telephonenumber, hometelephonenumber, otherhomephone, or othertelephone
For instance as below, after adding mobile and telephone number attribute values:

In VIP Manager:
- Go to Policies tab > Account tab, and enable SMS and Voice in ‘Enabled other credential types’

- Go to Policies tab > Components tab, and enable SMS and Voice in ‘Available distribution methods’

In VIP EG:
- Go to User Store tab > Search Criteria tab, and enable SMS and/or Voice in ‘Select Attribute’

- Go to Validation tab > select and edit the Validation Server, and enable ‘Enable User Store data for Out-of-Band’ in RADIUS Validation Server

- Go to Home tab, and ensure all changes are synchronized

- Go to User Store tab > LDAP Directory Synchronization, and click on Synchronize Now (if not already synchronized)
