CHAPTER 20 SIP Definitions
Mediant 4000 SBC | User's Manual
■ Registering each user to an external registrar server.
■ Authenticating (for any SIP request and as a client) each user if challenged by an external
server.
■ Authenticating as a server incoming user requests (for SBC security).
If the device registers on behalf of users and the users do not perform registration, any SIP request
destined to the user is routed to the Proxy Set associated with the user’s IP Group.
The User Information table can be configured using any of the following methods:
■ Web interface (see Configuring SBC User Info Table through Web Interface)
■ CLI (see Configuring SBC User Info Table through CLI)
■ Loadable User Information file (see Configuring SBC User Info Table in Loadable Text File)
● For the SBC User Information feature, the device's License Key must include the
license "Far End Users (FEU)", which specifies the maximum number of supported
far-end users. If no far-end users are licensed, then this feature cannot be used.
● If you configure the device to authenticate as a server the incoming SIP requests
from users of a specific User-type IP Group, the device authenticates the users,
using the username and password configured in the IP Group's 'Username' and
'Password' parameters. However, if the user appears in the User Information table
and configured with a username and/or password, then the device authenticates
the user with the credentials in the table. To enable the device to authenticate as a
server, configure the IP Group's 'Authentication Mode' parameter to
SBC as
Server .
