 To configure AMD for all calls:
1. Open the DSP Settings page (Setup menu > Signaling & Media tab > Media folder >
DSP Settings):
2. From the 'IPMedia Detectors' drop-down list (EnableDSPIPMDetectors), select
Enable to enable AMD.
3. Scroll down to the Answer Machine Detector group:
Figure 14-8: Configuring AMD
4. Select the AMD algorithm suite:
a. In the 'Answer Machine Detector Sensitivity Parameter Suite' field, select the
required Parameter Suite included in the installed AMD Sensitivity file.
b. In the 'Answer Machine Detector Sensitivity' field, enter the required detection
sensitivity level of the selected Parameter Suite.
5. Configure the answering machine beep detection:
a. In the 'Answer Machine Detector Beep Detection Timeout' field
(AMDBeepDetectionTimeout), enter the duration that the beep detector operates
from when detection is initiated.
b. In the 'Answer Machine Detector Beep Detection Sensitivity' field
(AMDBeepDetectionSensitivity), enter the AMD beep detection sensitivity level.
6. Click Apply, and then reset the device with a save-to-flash for your settings to take
effect.
For a complete list of AMD-related parameters, see 'IP Media Parameters' on page 1315.
14.5.2 Enabling IP-to-Tel Call Disconnection upon Detection of
Answering Machine
The device can disconnect an IP-to-Tel call upon detection of an answering machine on
the Tel side. Once detected, the device disconnects the call after the receipt of an ISDN
Connect from the Tel side and then sends a SIP BYE message to the IP side to disconnect
the call. You can enable this feature for all calls (globally) using the AMDmode parameter
(see procedure below) or for specific calls using IP Profiles where the IP Profile parameter
'AMD Mode' (IpProfile_AmdMode) is set to [1] Disconnect on AMD (see 'Configuring IP
Profiles' on page 436).
 To enable disconnection of IP-to-Tel call upon detection of answering machine:
1. Open the Gateway Advanced Settings page (Setup menu > Signaling & Media tab >
Gateway folder > Gateway Advanced Settings).

2. From the 'AMD Mode' drop-down list, select Disconnect on AMD, and then click
