User's Manual 458 Document #: LTRT-27055
Mediant 1000B Gateway & E-SBC
Parameter Description
The SDP contains the following line:
'a=rtpmap:100 X-NSE/8000'.
Note:
When enabled, the following conditions must also be met:
The Cisco gateway must include the following definition:
'modem passthrough nse payload-type 100 codec g711alaw'.
Set the Modem transport type to Bypass mode
(VxxModemTransportType is set to 2) for all modems.
Set the NSEPayloadType parameter to 100.
The corresponding global parameter is NSEMode.
Gateway Answering Machine
AMD Mode
amd-mode
[IpProfile_AmdMode]
Enables the device to disconnect the IP-to-Tel call upon detection of
an answering machine on the Tel side.
[0] Don't Disconnect = (Default) Device does not disconnect call
upon detection of an answering machine.
[1] Disconnect on AMD = Device disconnects call upon detection
of an answering machine. It disconnects the call only after receipt
of an ISDN Connect from the Tel side. In such a scenario, the
device sends a SIP BYE message upon AMD.
Note:
When the parameter is set to Disconnect on AMD [1]), the feature
can only function if the EnableEarlyAMD parameter is set to any
value other than [1].
This feature does not need the receipt of the SIP X-Detect header
in the incoming INVITE to activate the AMD.
The corresponding global parameter is AMDmode.
AMD Sensitivity Parameter
Suite
amd-sensitivity-parameter-suit
[IpProfile_AMDSensitivityPara
meterSuit]
Defines the AMD Parameter Suite to use for the Answering Machine
Detection (AMD) feature.
[0] 0 = (Default) Parameter Suite 0 based on North American
English with standard detection sensitivity resolution (8 sensitivity
levels, from 0 to 7). This AMD Parameter Suite is provided by the
AMD Sensitivity file, which is shipped pre-installed on the device.
[1] 1 = Parameter Suite based 1 on North American English with
high detection sensitivity resolution (16 sensitivity levels, from 0 to
15). This AMD Parameter Suite is provided by the AMD
Sensitivity file, which is shipped pre-installed on the device.
[2] 2 to [7]7 = Optional Parameter Suites that you can create
based on any language (16 sensitivity levels, from 0 to 15). This
requires a customized AMD Sensitivity file that needs to be
installed on the device. For more information, contact your
AudioCodes sales representative.
Note:
To configure the detection sensitivity level, use the 'AMD
Sensitivity Level' parameter.
For more information on the AMD feature, see Answering
Machine Detection (AMD) on page 209.
The corresponding global parameter is
AMDSensitivityParameterSuit.
AMD Sensitivity Level Defines the AMD detection sensitivity level of the selected AMD
