Version 6.4

[1] = The device changes the URI in the Contact header of the
received SIP 3xx response to its own URI and adds a special
user prefix ("T~&R_"), which is then sent to the FEU. The FEU
then sends a new INVITE to the device, which the device then
sends to the correct destination.
Notes:

When this parameter is changed from 1 to 0, new 3xx Contact
headers remain unchanged. However, requests with the special
prefix continue using the device's database to locate the new
destination.

Only one database entry is supported for the same host, port,
and transport combination. For example, the following URLs
cannot be distinguished by the device:

sip:10.10.10.10:5060;transport=tcp;param=a

sip:10.10.10.10:5060;transport=tcp;param=b

The database entry expires two hours after the last use.

The maximum number of destinations (i.e., database entries) is
50.


Defines the registration mode for an IP Group:

[0] User initiates registrations (default)

[1] SBC initiate registrations (works only with User Info file) =
Used when the device serves as a client (e.g., with an IP PBX)

[2] No registrations needed = The device adds users to its
database in active state.
Note: This is an IP Group table parameter.
Defines the authentication mode:

[0] User Authenticates (default) = The device does not handle
the authentication, but simply passes the authentication
messages between the SIP user agents.

[1] SBC Authenticates (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., user name and password)
according to one of the following: 1) account defined in the
Account 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).

[2] SBC Authenticates (as server) = The device authenticates
as a server (using the User Information file).
Note: This is an IP Group table parameter.
Defines the SIP methods that the device must challenge. Multiple
entries are separated by the forward slash "/". If none are defined
(default), no methods are challenged.
Note: This is an IP Group table parameter.
