User's Manual
Description
(parsing of call identifiers in XML body) in SIP
NOTIFY messages received from a remote
application server.

[0] Disable (default)

[1] Enable
For more information, see ''Interworking Dialog
Information in SIP NOTIFY Messages'' on page 485.
Global parameter that enables the device to use the
same call 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 418
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).
Public-GRUU:
sip:userA@domain.com;gr=unique-id
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.
