Version 6.4 777 March 2012
SIP User's Manual A. Configuration Parameters Reference
Parameter Description
EMS: Time Out
[AMDTimeout]
Defines the timeout (in msec) between receiving Connect messages
from the ISDN and sending AMD results.
The valid range is 1 to 30,000. The default is 2,000 (i.e., 2 seconds).
Web/EMS: AMD Beep
Detection Mode
[AMDBeepDetectionMode]
Determines the AMD beep detection mode. This mode detects the
beeps played at the end of an answering machine message, by
using the X-Detect header extension. The device sends a SIP INFO
message containing the field values Type=AMD and SubType=Beep.
This feature allows users of certain third-party, Application server to
leave a voice message after an answering machine plays the “beep”.
[0] Disabled (default)
[1] Start After AMD
[2] Start Immediately

Detector Beep Detection
Timeout
EMS: Beep Detection Timeout
[AMDBeepDetectionTimeout
]
Defines the AMD beep detection timeout (i.e., the duration that the
beep detector functions from when detection is initiated). This is
used for detecting beeps at the end of an answering machine
message.
The valid value is in units of 100 milliseconds, from 0 to 1638. The
default value is 200 (i.e., 20 seconds).

Detector Beep Detection
Sensitivity
EMS: Beep Detection
Sensitivity
[AMDBeepDetectionSensitiv
ity]
Defines the AMD beep detection sensitivity for detecting beeps at the
end of an answering machine message.
The valid value is 0 to 3, where 0 (default) is the least sensitive.
Energy Detector Parameters
Note: Currently, this feature is not supported.
Enable Energy Detector
[EnableEnergyDetector]
Enables the Energy Detector feature. This feature generates events
(notifications) when the signal received from the PSTN is higher or
lower than a user-defined threshold (defined by the
EnergyDetectorThreshold parameter).
[0] Disable (default)
[1] Enable
Energy Detector Quality
Factor
[EnergyDetectorQualityFact
or]
Defines the Energy Detector's sensitivity level.
The valid range is 0 to 10, where 0 is the lowest sensitivity and 10
the highest sensitivity. The default is 4.
Energy Detector Threshold
[EnergyDetectorThreshold]
Defines the Energy Detector's threshold. A signal below or above
this threshold invokes an 'Above' or 'Below' event.
The threshold is calculated as follows:
Actual Threshold = -44 dBm + (EnergyDetectorThreshold * 6)
The valid value range is 0 to 7. The default is 3 (i.e., -26 dBm).
Pattern Detection Parameters
Note: For an overview on the pattern detector feature for TDM tunneling, see DSP Pattern Detector
