Mediant 4000 SBC | User's Manual
Parameter Description
[SRD_SBCOperationMode] ■ [0] B2BUA = (Default) Device operates as a
back-to-back user agent (B2BUA), changing the
call identifiers and headers between the inbound
and outbound legs.
■ [1] Call Stateful Proxy = Device operates as a
Stateful Proxy, passing the SIP message
transparently between inbound and outbound
legs. In other words, the same SIP dialog
identifiers (tags, Call-Id and CSeq) occur on both
legs (as long as no other configuration disrupts
the CSeq compatibleness).
For more information on B2BUA and Stateful Proxy
modes, see
B2BUA and Stateful Proxy Operating
Modes .
Note:
■ The settings of the parameter also determines the
default behavior of related parameters in the IP
Profiles table (SBCRemoteRepresentationMode,
SBCKeepVIAHeaders,
SBCKeepUserAgentHeader,
SBCKeepRoutingHeaders,
SBCRemoteMultipleEarlyDialogs).
■ If the 'SBC Operation Mode' parameter is
configured in the IP Groups table, the 'SBC
Operation Mode' parameter in the SRDs table is
ignored.
'SBC Routing Policy'
sbc-routing-policy-name
[SRD_SBCRoutingPolicyName]
Assigns a Routing Policy to the SRD.
By default, no value is defined if you have configured
multiple Routing Policies. If you have configured only
one Routing Policy, the device assigns it to the SRD
by default.
For more information on Routing Policies, see
Configuring SBC Routing Policy Rules .
Note:
■ If you have assigned a Routing Policy to a
Classification rule that is associated with the
SRD, the Routing Policy assigned to the SRD is
ignored.
■ You can assign the same Routing Policy to
multiple SRDs.
'Used By Routing Server'
used-by-routing-server
[SRD_UsedByRoutingServer]
Enables the SRD to be used by a third-party routing
server for call routing decisions.
■ [0] Not Used (default)
