Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
'BroadWorks Survivability Feature'
configure voip > sbc settings >
sbc-broadworks-survivability
[SBCExtensionsProvisioningMode]
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] Disable = (Default) Normal
processing of REGISTER messages.
■ [1] Enable = 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 Enabling Auto-Provisioning of
Subscriber-Specific Information of
BroadWorks Server for Survivability.
'SBC Direct Media'
configure voip > sip-interface >
sbc-direct-media
[SBCDirectMedia]
Enables the Direct Media feature (i.e., no
Media Anchoring) 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).
■ [1] Enable = Direct media flow between
endpoints for all SBC calls.
Note:
■ The setting of direct media in the SIP
Interfaces table overrides this global
parameter. In other words, even if the
parameter is disabled for direct media
(i.e., Media Anchoring is enabled), if
direct media is enabled for a SIP
Interface (in the SIP Interfaces table),
calls between endpoints belonging to
the SIP Interface employ direct media.
■ For more information on No Media
Anchoring, see Direct Media.
