[EnableSBCApplication]

[1] Enable (default)
Note:

For the parameter to take effect, a device reset is required.

The parameter is enabled by default only if the License Key
contains at least one of the SBC-related capacity features (e.g.,
"SBC-Signaling"); otherwise, the parameter is disabled.
SBC and CRP Parameters
WAN Interface Name
[WanInterfaceName]
Defines the WAN interface for the VoIP interface. The available
interface options depends on the hardware configuration (e.g., Ethernet
or SHDSL) and/or whether VLANs are defined for the WAN interface.
The value must be enclosed in single quotation marks ('...'), for
example, WanInterfaceName = 'GigabitEthernet 0/0'.
This WAN interface can be assigned to SIP signaling and/or media
interfaces, in the SIP Interfaces table, where it is represented as
"WAN" (see Configuring SIP Interfaces on page 325). If VLANs are
configured, for example, for the Ethernet WAN interface, then you can
select the WAN VLAN on which you want to run these SIP signaling
and/or media interfaces. Therefore, for each outgoing SIP packet, the
device sends it on the defined outgoing WAN interface; for each
incoming SIP packet, the device identifies the packet according to the
WAN interface from where it is received.
Note:

For the parameter to take effect, a device reset is required.

The parameter is applicable only if the data-routing feature is
supported (i.e., relevant License Key is installed on the device).
Unclassified Calls
configure voip > sbc
settings > unclassified-
calls
[AllowUnclassifiedCalls]
Determines whether incoming calls that cannot be classified (i.e.
classification process fails) to a Source IP Group are rejected or
processed.

[0] Reject = (Default) Call is rejected if classification fails.

[1] Allow = If classification fails, the incoming packet is assigned to
a source IP Group (and subsequently processed) as follows:

The source SRD is determined according to the SIP Interface to
where the SIP-initiating dialog request is sent. The source IP
Group is set to the default IP Group associated with this SRD.

If the source SRD is ID 0, then source IP Group ID 0 is chosen.
In case of any other SRD, then the first IP Group associated
with this SRD is chosen as the source IP Group or the call. If no
IP Group is associated with this SRD, the call is rejected.
SBC Max Call Duration
configure voip > sbc
settings > sbc-mx-call-
duration
[SBCMaxCallDuration]
Defines the maximum duration (in minutes) per SBC call (global). If the
duration is reached, the device terminates the call.
The valid range is 0 to 35,791, where 0 is unlimited duration. The
default is 0.
Note: You can also configure this feature per specific calls, using IP
Profiles (IpProfile_SBCMaxCallDuration). For a detailed description of
the parameter and for configuring this feature in the IP Profiles table,
see Configuring IP Profiles on page 404. If this feature is configured for
a specific IP Profile, the settings of this global parameter is ignored for
calls associated with the IP Profile.
SBC No Answer Timeout
configure voip > sbc
settings > sbc-no-arelt-
timeout
Defines the timeout (in seconds) for SBC outgoing (outbound IP
routing) SIP INVITE messages. If the called IP party does not answer
the call within this user-defined interval, the device disconnects the
session. The device starts the timeout count upon receipt of a SIP 180
Ringing response from the called party. If no other SIP response (for
