15.5.1 Configuring AMD

You can configure AMD for all calls using the global AMD parameters, or for specific calls

using IP Profiles. The procedure below describes how to configure AMD for all calls. For

configuring AMD for specific calls, use the AMD parameters in the IP Profile table (see

''Configuring IP Profiles'' on page 391). For Gateway calls, AMD can be configured per call

based on the called number or Trunk Group. This is achieved by configuring AMD for a

specific IP Profile and then assigning the IP Profile to a Trunk Group in the Inbound IP

Routing table (see Configuring IP-to-Trunk Group Routing Rules on page 505).

 To enable and configure AMD for all calls:

1. Open the IPMedia Settings page (Configuration tab > VoIP > Media > IPMedia

Settings):

Figure 15-8: Configuring AMD Parameters in the IPMedia Settings Page

2. From the 'IPMedia Detectors' drop-down list (EnableDSPIPMDetectors), select

Enable to enable AMD.

3. Select the AMD algorithm suite:

a. In the 'Answer Machine Detector Sensitivity Parameter Suit' 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.

4. 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.

5. Click Submit, and then reset the device with a burn-to-flash for your settings to take

effect.

For a complete list of AMD-related parameters, see ''IP Media Parameters'' on page 1048.
