User's Manual
Defines the device's operational mode for the SRD.

[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).

[2] Microsoft Server = Operating mode for the One-Voice Resiliency
feature, whereby the device is deployed together with Lync-compatible
IP Phones at small remote branch offices in a Microsoft® Lync™
environment.
For more information on B2BUA and Stateful Proxy modes, see B2BUA
and Stateful Proxy Operating Modes on page 549.
Notes:

The settings of the parameter also determines the default behavior of
related parameters in the IP Profile table
(SBCRemoteRepresentationMode, SBCKeepVIAHeaders,
SBCKeepUserAgentHeader, SBCKeepRoutingHeaders,
SBCRemoteMultipleEarlyDialogs).

If the 'SBC Operation Mode' parameter is configured in the IP Group
table, the 'SBC Operation Mode' parameter in the SRD table is
ignored.
Assigns an SBC Routing Policy to the SRD.
By default, no value is defined (None) if you have configured multiple
SBC Routing Policies. If you have configured only one SBC Routing
Policy, the device assigns it to the SRD by default.
For more information on SBC Routing Policies, see Configuring SBC
Routing Policy Rules on page 616.
Notes:

If you have assigned an SBC Routing Policy to a Classification rule
that is associated with the SRD, the SBC Routing Policy assigned to
the SRD is ignored.

You can assign the same Routing Policy to multiple SRDs.
Defines the maximum number of users belonging to the SRD that can
register with the device.
The default is -1, which means that the number of allowed user
registrations is unlimited.
Enables the device to block (reject) incoming calls (INVITE requests) from
unregistered users belonging to the SRD.

[0] No = (Default) Calls from unregistered users are allowed.

[1] Yes = Calls from unregistered users are blocked.
Notes:

When the device blocks a call, it sends a SIP 500 "Server Internal
Error" response to the remote end.

The parameter applies to calls belonging to a User-type IP Group.

When the corresponding parameter in the SIP Interface table
(SIPInterface_BlockUnRegUsers) is configured to Yes or No for a SIP
