Parameter Description
Alternative Routing to Trunk upon Q.931 Call Release Cause
Code on page 424.
Web: Enable Microsoft
Extension
CLI: 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
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
Manipulation tables to leave only the last 3 digits (for example) for
sending to a PBX.
EMS: Use SIP URI For
Diversion Header
[UseSIPURIForDiversionHea
der]
Defines the URI format in the SIP Diversion header.

[TimeoutBetween100And18
x]
Defines the timeout (in msec) between receiving a 100 Trying
response and a subsequent 18x response. If a 18x response is not
received within this timeout period, the call is disconnected.
The val
id range is 0 to 180,000 (i.e., 3 minutes). The default is 32000
(i.e., 32 sec).
[EnableImmediateTrying] Determines if and when the device sends a 100 Trying in response
to an incoming INVITE request.
 [0] = 100 Trying response is sent upon receipt of a Proceeding
message from the PSTN
 [1] = (Default) 100 Trying response is sent immediately upon
receipt of INVITE request.

n]
Determines the format of the Transparent coder representation in the
SDP.
 [0] = clearmode (default)
 [1] = X-CCD

(MKI) if present in the SDP received from the remote side.
 [0] Disable (default)

[1]
Enable
[TrunkStatusReportingMode] Determines whether the device responds to SIP OPTIONS if all the
trunks pertaining to Trunk Group #1 are down.
