SIP User's Manual 6. Configuration Parameters Reference
Parameter Description
Enable Microsoft Extension
[EnableMicrosofExt]
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., e622125519100104). Once modified, the
device can then manipulate the number further, using the
Number Manipulation tables (refer to ''Number Manipulation
and Routing Parameters'' on page 328) to leave only the
las
t 3 digits (for example) for sending to a PBX.
Web/EMS: Hook-Flash Code
[HookFlashCode]
Defines a digit pattern that when received from the Tel side,
indicates a Hook Flash event.
The valid range is a 25-character string. The default is a
null string.
EMS: Use SIP URI For Diversion
Header
[UseSIPURIForDiversionHeader]
Sets the URI format in the SIP Diversion header.
[0] = 'tel:' (default)
[1] = 'sip:'
[TimeoutBetween100And18x]
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).
First Call Ringback Tone ID
[FirstCallRBTId]
Determines the index of the first Ringback Tone in the CPT
file. This option enables an Application server to request
the device to play a distinctive Ringback tone to the calling
party according to the destination of the call. The tone is
played according to the Alert-Info header received in the
180 Ringing SIP response (the value of the Alert-Info
header is added to the value of this parameter).
The valid range is -1 to 1,000. The default value is -1 (i.e.,
play standard Ringback tone).
Notes:
It is assumed that all Ringback Tones are defined in
sequence in the CPT file.
In case of an MLPP call, the device uses the value of
this parameter plus 1 as the index of the Ringback tone
in the CPT file (e.g., if this value is set to 1, then the
index is 2, i.e., 1 + 1).
