identification (SIP Call-ID header value) received in incoming
messages for the call identification in outgoing messages. The
call identification value is contained in the SIP Call-ID header.
You can also configure the functionality per specific calls, using
IP Profiles. For a detailed description of the parameter and for
configuring the functionality in the IP Profiles table, see
Configuring IP Profiles on page 405.
Determines the Globally Routable User Agent (UA) URI
(GRUU) support, according to RFC 5627.

[0] None = No GRUU is supplied to users.

[1] As Proxy = (Default) The device provides same GRUU
types as the proxy provided the device's GRUU clients.

[2] Temporary only = Supply only temporary GRUU to
users. (Currently not supported.)

[3] Public only = The device provides only public GRUU to
users.

[4] Both = The device provides temporary and public GRUU
to users. (Currently not supported.)
The parameter allows the device to act as a GRUU server for
its SIP UA clients, providing them with public GRUU's,
according to RFC 5627. The public GRUU provided to the client
is denoted in the SIP Contact header parameters, "pub-gruu".
Public GRUU remains the same over registration expirations.
On the other SBC leg communicating with the Proxy/Registrar,
the device acts as a GRUU client.
The device creates a GRUU value for each of its registered
clients, which is mapped to the GRUU value received from the
Proxy server. In other words, the created GRUU value is only
used between the device and its clients (endpoints).

Enables authenticating a SIP BYE request before disconnecting
the call. This feature prevents, for example, a scenario in which
the SBC SIP client receives a BYE request from a third-party
imposer assuming the identity of a participant in the call and as
a consequence, the call between the first and second parties is
inappropriately disconnected.

[0] Disable (default)

[1] Enable = The device forwards the SIP authentication
response (for the BYE request) to the request sender and
waits for the user to authenticate it. The call is disconnected
only if the authenticating server responds with a 200 OK.
Enables the device to send SIP 100 Trying responses upon
receipt of SUBSCRIBE or NOTIFY messages.

[0] Disable (Default)

[1] Enable
Enables SBC user registration for interoperability with
BroadSoft's BroadWorks server, to provide call survivability in
case of connectivity failure with the BroadWorks server.

[0] Disable = (Default) Normal processing of REGISTER
