Mediant 3000
Parameter Description

[1] Force = Forces transcoding on the outgoing SBC leg. The
device's SBC application interworks the media by implementing
DSP transcoding.
Note: This parameter can also be configured in an IP Profile.
Web: SBC Preferences
Mode
[SBCPreferencesMode]
Determines the order of the Extension coders (coders added if there
are no common coders between SDP offered coders and Allowed
coders) and Allowed coders (defined in the Allowed Coders Group
table) in the outgoing SIP message (in the SDP).

[0] Doesn’t Include Extensions = (Default) Extension coders are
added at the end of the coder list.

[1] Include Extensions = Extension coders and Allowed coders
are arranged according to their order of appearance in the
Allowed Coders Group table.
Note: If the SBCExtensionCodersGroupID parameter of the IP
Profile table is set to None, then this parameter is not applicable.
Web: SBC Send Invite To All
Contacts
CLI: sbc-send-invite-to-all-
contacts
[SBCSendInviteToAllConta
cts]
Enables call forking of INVITE message received with a Request-
URI for 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
Note: To configure call forking initiated by the device, see Initiating
SIP Call Forking.
Web: SBC Shared Line
Registration Mode
CLI: sbc-shared-line-reg-
mode
[SBCSharedLineRegMode]
Enables the termination on the device of SIP REGISTER messages
from secondary lines pertaining 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.
Web: SBC Forking Handling
Mode
[SBCForkingHandlingMode
]
Defines the handling of SIP 18x responses 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
responds according to the PlayRBTone2TEL parameter and
disregards the subsequent forking 18x responses.

[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 forwarded to the INVITE-
initiating UA and subsequent 18x responses are discarded.
[EnableSBCMediaSync] Enables SBC media synchronization process for calls established
from SIP forking that is initiated by external proxy servers. It is
possible that a call is established with the media not synchronized
between the SBC legs. Media synchronization resolves this issue.

[0] Disable

[1] Enable (default)
