User's Manual 1162 Document #: LTRT-27045
Mediant 1000B Gateway & E-SBC
Parameter Description
The lowest expiry time that the device sends in the 200 OK,
regardless of the resultant calculation, is 10 seconds. For
example, if the original expiry time is 12 seconds and the
parameter is set to 5, theoretically, the new expiry time can
be less than 10 (e.g., 12 – 4 = 8). However, the expiry time
will be set to 10.
The expiry time received from the user can be changed by
the device before forwarding it to the proxy. This is
configured by the SBCUserRegistrationTime parameter.
SBC Survivability Registration Time
configure voip > sbc settings > sbc-
surv-rgstr-time
[SBCSurvivabilityRegistrationTime]
Defines the duration of the periodic registrations between the
user and the device, when the device is in survivability state
(i.e., when REGISTER requests cannot be forwarded to the
proxy and are terminated by the device). When set to 0, the
device uses the value set by the SBCUserRegistrationTime
parameter for the device's response.
The valid range is 0 to 2,000,000 seconds. The default is 0.
configure voip > sbc
settings > sas-notice
[SBCEnableSurvivabilityNotice]
Enables the device to notify Aastra IP phones that the device
is currently operating in Survivability mode.
[0] = Disable
[1] = Enable
For more information, see ''Enabling Survivability Display on
Aastra IP Phones'' on page 713.
SBC Dialog-Info Interworking
configure voip > sbc settings > sbc-
dialog-info-interwork
[EnableSBCDialogInfoInterworking]
Enables the interworking of dialog information (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 641.
configure voip > sbc settings > sbc-
keep-call-id
[SBCKeepOriginalCallId]
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 393.
SBC GRUU Mode
configure voip > sbc settings > 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.)
The parameter allows the device to act as a GRUU server for
its SIP UA clients, providing them with public GRUU’s,
