The IP media parameters are described in the table below.

IP Media Parameters

Parameter

Description

'IPMedia Detectors'

configure voip > media ipmedia > ipm-detectors-enable

[EnableDSPIPMDetectors]

Enables the device's DSP detectors for detection features such as AMD.

[0] Disable (default)
[1] Enable

Note:

For the parameter to take effect, a device reset is required.
The DSP Detectors feature is available only if the device is installed with a License Key that includes this feature. For installing a License Key, see License Key.
When enabled (1), the number of available channels is reduced.

Conferencing Parameters

'Conference ID'

configure voip > gateway dtmf-supp-service supp-service-settings > conf-id

[ConferenceID]

Defines the Conference Identification string.

The valid value is a string of up to 16 characters. The default is "conf".

Note: To join a conference, the INVITE URI must include the Conference ID string preceded by the number of the participants in the conference and terminated by a unique number. For example:

INVITE sip:4conf1234@10.1.10.10

INVITE messages with the same URI join the same conference.

'AMD Beep Detection Mode'

configure voip > sip-definition settings > amd-beep-detection

[AMDBeepDetectionMode]

Defines 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.
