Determines the device's interworking of ALERT messages from PRI
to SIP.

[0] = Disabled (default).

[1] = Enabled.
When enabled, if the device already sent a 183 response with an
SDP included and an ALERT message is received from the Tel side
(with or without Progress Indicator), the device does not send an
additional 18x response and the voice channel remains open.
When disabled, the device sends additional 18x responses as a
result of receiving an ALERT message whether or not a 18x
response was already sent.
Modifies the called 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
party.

[0] = Disabled (default).

[1] = Enabled.
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.,
device can then manipulate the number further, using the Number
Manipulation tables (refer to ''Number Manipulation and Routing
Parameters'' on page 348
example) for sending to a PBX.
Determines the digit pattern used by the PBX to indicate a Hook
Flash event. When this pattern is detected from the Tel side, the
device responds as if a Hook Flash event occurs and sends a SIP
INFO message if HookFlashOption is set to 1, indicating Hook Flash.
If configured and a Hook Flash indication is received from the IP
side, the device generates this pattern to the Tel side.
The valid range is a 25-character string. The default is a null string.
Sets 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 before this timer expires, the call is disconnected.
The valid range is 0 to 32,000. The default value is 0 (i.e., no
timeout).
