User's Manual 43. Configuration Parameters Reference
Parameter Description
n]
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 authe
nticate 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
[SBCExtensionsProvisioning
Mode]
Enables SBC user registration for interoperability with BroadSoft's
BroadWorks server, to provide call survivability in case of
connectivity failure with the BroadWorks server.
 [0] = (Default) Normal processing of REGISTER messages.
 [1] = Registration method for BroadWorks server. In a failure
scenario with BroadWorks, the device acts as a backup SIP
proxy server, maintaining call continuity between the enterprise
LAN users (subscribers) and between the subscribers and the
PSTN (if provided).
Note: For a detailed description of this feature, see ''Auto-
Provisioning of Subscriber-Specific Information for BroadWorks
Server'' on page 345.
Web: SBC Direct Media
CLI: sbc-direct-media
[SBCDirectMedia]
Enables the No Media Anchoring feature (i.e., direct media) for all
SBC calls, whereby SIP signaling is handled by the device without
handling the RTP/SRTP (media) flow between the user agents
(UA). The RTP packets do not traverse the device. Instead, the two
SIP UAs establish a direct RTP/SRTP flow between one another.
Signaling continues to traverse the device with minimal
intermediation and involvement to enable certain SBC abilities such
as routing
 [0] Disable = (Default) All calls traverse the device (i.e., no
direct media). If No Media Anchoring is enabled for an SRD (in
the SRD table), then calls between endpoints belonging to that
SRD use No Media Anchoring.
 [1] Enable = All SBC calls use the No Media Anchoring feature
(i.e., direct media).
Note: For more information on No Media Anchoring, see ''No
Media Anchoring (Anti Tromboning)'' on page 329.
Web: Transcoding Mode
CLI: transcoding-mode
[TranscodingMode]
Global parameter that defines the voice transcoding mode (media
negotiation). You can also configure this functionality per specific
calls, using IP Profiles (IpProfile_TranscodingMode). For a detailed
description of this parameter and for configuring this functionality in
the IP Profile table, see Configuring IP Profiles on page 297.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
