SIP User's Manual   A. Configuration Parameters Reference 
Parameter  Description 
The default value is 0 (i.e., don't set this parameter on recognition 
attempt). 
Note: For this parameter to take effect, a device reset is required. 
[VxmlInterDigitTimeout] 
Defines the inter-digit timeout value (in msec) used when DTMF is 
received.  The valid range for this parameter is 0 to 7,000 msec. The 
default value is 3,000. 
Note: For this parameter to take effect, a device reset is required. 
[VxmlMaxActiveFiles] 
Defines the maximum number of static VXML scripts that can be 
loaded to the system at any one time. 
The valid range for this parameter is 0 to 30. The default value is 10. 
Note: This parameter does not affect the number of dynamic scripts 
that can be simultaneously active. 
Note: For this parameter to take effect, a device reset is required. 
[VxmlMaxPorts] 
Defines the number of channels in the system that can 
simultaneously run VXML scripts. The range is from 0 to the 
maximum number of channels in the system. This value can be used 
to ensure there are sufficient VXML resources for each call. For 
example, if the system is running dynamic scripts that each requires 
many resources, the VxmlMaxPorts value can be lowered to help 
ensure that each individual call has adequate resources. 
The default value is 0. 
Note: For this parameter to take effect, a device reset is required. 
[VxmlMaxSpeechTimeout] 
Defines the maximum time the caller can speak (in msec) in an 
attempt to match a speech grammar before a no match event is 
thrown. 
The range is 0 - 7,000. The default value is 0 (i.e., no time limit in the 
speech recognition attempt). 
Note: For this parameter to take effect, a device reset is required. 
[VxmlNoInputTimeout] 
Defines the no input timeout for digit (DTMF) collection or speech 
recognition (in msec). 
The range is 0 - 7,000. The default value is 3,000. 
Note: For this parameter to take effect, a device reset is required. 
[VxmlSensitivityLevel] 
Defines the default speech recognition sensitivity level for VXML. 
The valid range for this parameter is 0 to 100. The default value is 
50. 
Note: For this parameter to take effect, a device reset is required. 
[VxmlSpeedVsAccuracy] 
Defines the hint to the speech recognition engine for the balance of 
speed vs. accuracy. 
The valid range is from 0 to 100. The default value is 50. 
A low number means the speech recognition engine must perform 
recognition rapidly, at the cost (i.e., trade off) of accuracy. A high 
number, such as 100, means the speech recognition engine must 
perform the speech recognition accurately, at the cost of speed. 
Note: For this parameter to take effect, a device reset is required.
