Defines the maximum number of users in this IP Group that can
register with the device.
The default is -1, meaning that no limitation exists for registered users.
Note: The parameter is applicable only to User-type IP Groups.
Defines the registration mode for the IP Group:

[0] User Initiates Registration (default)

[1] SBC Initiates Registration = Used when the device serves as a
client (e.g., with an IP PBX). This functions only with the User Info
file.

[2] Registrations not Needed = The device adds users to its
database in active state.
Defines the authentication mode.

[0] User Authenticates = (Default) The device does not handle the
authentication, but simply forwards the authentication messages
between the SIP user agents.

[1] SBC as Client = The device authenticates as a client. It receives
the 401/407 response from the proxy requesting for authentication.
The device sends the proxy the authorization credentials (i.e.,
username and password) according to one of the following:
1)Account configured in the Accounts table (only if authenticating
Server-type IP Group), 2) global username and password
parameters (only if authenticating Server-type IP Group), 3) User
Information file, or 4) sends request to users requesting credentials
(only if authenticating User-type IP Group). For more information
on Accounts, see Configuring Registration Accounts on page 351.

[2] SBC as Server = The device acts as an Authentication server:

Authenticates SIP clients, using the usernames and passwords
in the User Information table (see SBC User Information for
SBC User Database on page 577). This is applicable only to
User-type IP Groups.

Authenticates SIP severs. This is applicable only to Server-
type IP Groups.
Defines SIP methods received from the IP Group that must be
challenged by the device when the device acts as an Authentication
server. If no methods are configured, the device doesn't challenge any
methods.
By default, no value is defined. To define multiple SIP methods, use
the backslash ( \ ) to separate each method (e.g., INVITE\REGISTER).
Note: The parameter is applicable only if the 'Authentication Mode'
parameter is set to SBC as Server [2].
Defines the shared username for authenticating the IP Group, when
the device acts as an Authentication server.
The valid value is a string of up to 51 characters. By default, no
username is defined.
