Parameter Description
For more information, see ''Interworking Dialog Information in SIP
NOTIFY Messages'' on page 545.
CLI: sbc-keep-call-id
[SBCKeepOriginalCallId]
Enables the device to use the same call identification value
received in incoming messages for the call identification in
outgoing messages. The call identification value is contained in
the SIP Call-ID header.
[0] = (Default) Disable - the device creates a new Call-ID
value for the outgoing message.
[1] = Enable - the device uses the received Call-ID value of
the incoming message in the outgoing message.
Note: When the device sends an INVITE as a result of a
REFER/3xx termination, the device always creates a new Call-ID
value and ignores this parameter's settings.
Web: SBC GRUU Mode
CLI: sbc-gruu-mode
[SBCGruuMode]
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.)
This 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
Web: Bye Authentication
CLI: sbc-bye-auth
[SBCEnableByeAuthentication]
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.
Web: SBC Enable Subscribe
Trying
CLI: configure voip > sbc general-
setting > set sbc-subs-try
[SBCSendTryingToSubscribe]
Enables the device to send SIP 100 Trying responses upon
receipt of SUBSCRIBE or NOTIFY messages.
[0] Disable (Default)
[1] Enable
