
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 493.

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 486.

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 520.
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.
Defines the URI format in the SIP Diversion header.

[0] = 'tel:' (default)

[1] = 'sip:'
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 valid range is 0 to 180,000 (i.e., 3 minutes). The default is 32000
(i.e., 32 sec).
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.
Determines the format of the Transparent coder representation in the
SDP.

[0] = clearmode (default)

[1] = X-CCD
