SIP User's Manual
stream. The device passes packets RTP to RTP packets without
any processing.

[1] Force = Force transcoding on the outgoing IP leg. The device
interworks the media by implementing DSP transcoding. (default)
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 470.
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 parameters is ignored.
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 294.

For a list of SIP responses-Q.931 release cause mapping, see
'Release Reason Mapping' on page 261.
Enables the modification of the called and calling number for numbers
received with Microsoft's proprietary "ext=xxx" parameter in the SIP
INVITE URI user part. Microsoft Office Communications Server
sometimes uses this proprietary parameter to indicate the extension
number of the called or calling party.

[0] Disable (default)

[1] Enable
For example, if a calling party makes a call to telephone number
622125519100 Ext. 104, the device receives the SIP INVITE (from
Microsoft's application) with the URI user part as INVITE
sip:622125519100;ext=104@10.1.1.10 (or INVITE
tel:622125519100;ext=104). If the parameter EnableMicrosofExt is
enabled, the device modifies the called number by adding an "e" as
the prefix, removing the "ext=" parameter, and adding the extension
number as the suffix (e.g., e622125519100104). Once modified, the
device can then manipulate the number further, using the Number
