Chapter 6 User Group Management
Basic User Group Settings
Perform this procedure to enable support for the null password function of VoIP.
This enables users to authenticate (session or telephone call) on only the user ID
(telephone number).
When you enable VoIP at the group level, all users in this group become VoIP
users, and the user IDs are treated similarly to a telephone number. VoIP users do
not need to enter passwords to authenticate.
Caution Enabling VoIP disables password authentication and most advanced settings,
including password aging and protocol attributes.
To enable VoIP support for a group, follow these steps:
Step 1 In the navigation bar, click Group Setup.
The Group Setup Select page opens.
Step 2 From the Group list, select the group you want to configure for VoIP support, and
then click Edit Settings.
The Group Settings page displays the name of the group at its top.
Step 3 In the Voice-over-IP Support table, select the check box labeled This is a
Voice-over-IP (VoIP) group - and all users of this group are VoIP users.
Step 4 To save the group settings you have just made, click Submit.
For more information, see
Saving Changes to User Group Settings, page 6-56 .
Step 5 To continue, and specify other group settings, perform other procedures in this
chapter, as applicable.
