Mediant 3000
Parameter Description
parameter. If the Transparent coder is not defined, the default is set to
56. The payload type is negotiated with the remote side, i.e., the
selected payload type is according to the remote side selection. The
receiving device must include the 'Transparent' coder in its coder list.
Web: IP to IP Application
[EnableIP2IPApplication
]
Enables the IP-to-IP Call Routing application.

[0] Disable (default)

[1] Enable
Note: For this parameter to take effect, a device reset is required.
[IP2IPTranscodingMode
] Note: This parameter is no longer valid and must not be used.
Defines the voice transcoding mode (media negotiation) between two
user agents for the IP-to-IP application. This parameter must always be
set to 1 when using the IP-to-IP application.

[0] Only if Required = Do not force transcoding. Many of the media
settings (such as gain control) are not implemented on the voice
stream. The device passes packets RTP to RTP packets without any
processing.

[1] Force = (Default) Force transcoding on the outgoing IP leg. The
device interworks the media by implementing DSP transcoding.
Web: Enable RFC 4117
Transcoding
[EnableRFC4117Transc
oding]
Enables transcoding of calls according to RFC 4117.

[0] Disable (default)

[1] Enable
Notes:

For this parameter to take effect, a device reset is required.

For more information on transcoding, see Transcoding using Third-
Party Call Control on page
499 .
Web: Enable Single DSP
Transcoding
[EnableSingleDSPTrans
coding]
Enables the use of a single DSP for transcoding between G.711 and
LBR coders.

[0] Disable (default)

[1] Enable
Notes:

For this parameter to take effect, a device reset is required.

If the TranscodingMode and IP2IPTranscodingMode parameters are
set to 1 (i.e., Force), then this parameter is ignored.
Web/EMS: Default
Release Cause
[DefaultReleaseCause]
Defines the default Release Cause (sent to IP) for IP-to-Tel calls when
the device initiates a call release and an explicit matching cause for this
release is not found.
The default release cause is NO_ROUTE_TO_DESTINATION (3).
Other common values include NO_CIRCUIT_AVAILABLE (34),
DESTINATION_OUT_OF_ORDER (27), etc.
Notes:

The default release cause is described in the Q.931 notation and is
translated to corresponding SIP 40x or 50x values (e.g., 3 to SIP
404, and 34 to SIP 503).


When the Trunk is disconnected or is not synchronized, the internal
cause is 27. This cause is mapped, by default, to SIP 502.

For mapping SIP-to-Q.931 and Q.931-to-SIP release causes, see
Configuring Release Cause Mapping on page
348 .
