Mediant 1000B Gateway & E-SBC
Parameter Description
[NumberOfActiveDialogs]
The valid range is 1 to 20. The default is 20.
Note:
Once a 200 OK is received in response to a REGISTER message,
the REGISTER message is not considered in this maximum count
limit.
The parameter applies only to outgoing REGISTER messages
(i.e., incoming is unlimited).
[TransparentCoderOnDataC
all]
[0] = (Default) Only use coders from the coder list.
[1] = Use Transparent coder for data calls (according to RFC
4040).
The Transparent coder can be used on data calls. When the device
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the
coder is not included in the coder list).
The initiated INVITE includes the following SDP attribute:
a=rtpmap:97 CLEARMODE/8000
The default payload type is set according to the CodersGroup
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.
Note: The parameter is applicable only to digital interfaces.
Default Release Cause

[DefaultReleaseCause]
Defines the default Release Cause (sent to IP) for IP-to-
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.
Note:
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).
Analog: For more information on mapping PSTN release causes to
SIP responses, see Mapping PSTN Release Cause to SIP
Response on page 567.
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 559.
For a list of SIP responses-Q.931 release cause mapping, see
Alternative Routing to Trunk upon Q.931 Call Release Cause Code
on page 535.
Enable Microsoft Extension

definition settings >
microsoft-ext
[EnableMicrosoftExt]
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
