Viewing SBC Registered Users

You can view SBC users that are registered with the device. Each Address of Record (AOR) can have up to 10 registered contacts.

This section is applicable only to the SBC application.

The following procedure describes how to view registered users through the web interface. You can also view them through CLI - show voip register db sbc list or show voip register db sbc user <Address Of Record>.

➢ To view registered SBC users:
■ Open the SBC Registered Users page (Monitor menu > Monitor tab > VoIP Status folder > SBC Registered Users).

The 'Number Of AORs' read-only field displays the number of AORs in the registration database. You can search for a specific AOR, by entering the user part of its SIP URI in the search field. You must enter the full user part (not partial). For example, to search for AOR 1000@10.8.5.91, enter "1000".

To view detailed information of a contact associated with an AOR, simply click the contact's row in the table; a pane appears below the table, displaying the contact's information, as described below:

Parameter

Description

Basic Details

'Contact'

Displays a contact associated with the Address of Record (AOR). If the contact is registered, the field shows the contact of the SIP REGISTER request.

If the user is from the SBC User Information table (see Configuring SBC User Information Table through Web Interface), the field shows an arbitrarily constant value (e.g., "sip:ANY@CONTACT").

'Associated Contact'

Displays the contact or part of the contact in the outgoing SIP REGISTER request that is forwarded by the device to the registrar server.

Note: This field is not applicable when the contact is from the SBC User Information table (see Configuring SBC User Information Table through Web Interface).

'User IP Group'

Displays the IP Group associated with the contact (classified to this IP Group).

'Status'

Displays the registration status:

■ "Active": The contact is successfully registered with the device and calls for the contact can be processed.
■ "Inactive": The contact is currently not active. Possible causes may also include that the contact is in the middle of the initial registration process, or the contact's registration has expired.
