Parameter Description
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'' on page 650.
SBC RTCP Mode
configure voip > sbc settings > sbc-
rtcp-mode
[SBCRTCPMode]
Global parameter that defines the handling of RTCP packets.
You can also configure this functionality per specific calls,
using IP Profiles (IPProfile_SBCRTCPMode). For a detailed
description of the parameter and for configuring this
functionality in the IP Profiles table, see ''Configuring IP
Profiles'' on page 438.
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.
SBC Send Invite To All Contacts
configure voip > sbc settings > sbc-
send-invite-to-all-contacts
[SBCSendInviteToAllContacts]
Enables call forking of INVITE message received with a
Request-URI of a specific contact registered in the device's
database, to all users under the same AOR as the contact.
 [0] Disable (default) = Sends the INVITE only to the contact
of the received Request-URI.
 [1] Enable
To configure call forking initiated by the device, see ''Initiating
SIP Call Forking'' on page 757.
SBC Shared Line Registration
Mode
configure voip > sbc settings > sbc-
shared-line-reg-mode
[SBCSharedLineRegMode]
Enables the termination on the device of SIP REGISTER
messages from secondary lines that belong to the Shared Line
feature.
 [0] Disable = (Default) Device forwards the REGISTER
messages as is (i.e., not terminated on the device).
 [1] Enable = REGISTER messages of secondary lines are
terminated on the device.
Note: The device always forwards REGISTER messages of
the primary line.
SBC Forking Handling Mode
configure voip > sbc settings > sbc-
forking-handling-mode
[SBCForkingHandlingMode]
Defines the handling of SIP 18x responses that are received
due to call forking of an INVITE.
 [0] Latch On First = (Default) Only the first 18x is forwarded
to the INVITE-initiating UA. If SIP 18x with SDP is received,
the device opens a voice stream according to the received
SDP and disregards any subsequent 18x forking responses
(with or without SDP). If the first response is 180 without
SDP, the device sends it to the other side.
 [1] Sequential = All 18x responses are forwarded, one at a
time (sequentially) to the INVITE-initiating UA. If a 18x
arrives with an offer only, then only the first offer is
