74.11 Answer and Disconnect Supervision Parameters
The answer and disconnect supervision parameters are described in the table below.
Table 74-71Answer and Disconnect Parameters
Parameter Description
Wait before PSTN
Release-Ack
wait-befor-pstn-rel-ack
[TimeToWaitForPstnRele
aseAck]
Defines a timeout (in milliseconds) that the device waits for the receipt
of an ISDN Q.931 Release message from the PSTN side before
releasing the channel. The Release ACK is typically sent by the PSTN
in response to the device's Disconnect message to end the call. If the
timeout expires and a Release message has not yet been received, the
device releases the call channel.
The valid value is 1 to 360,000. The default is 6,000.
Note: The parameter is applicable only to digital interfaces.

[EnableVoiceDetection]
Enables the sending of SIP 200 OK upon detection of speech, fax, or
modem.

[1] Yes = The device sends a SIP 200 OK (in response to an INVITE
message) when speech, fax, or modem is detected (from the Tel
side, for analog interfaces).

[0] No = (Default) The device sends a SIP 200 OK only after it
completes dialing (to the Tel side, for analog interfaces).
Typically, this feature is used only when early media (enabled using the
EnableEarlyMedia parameter) is used to establish the voice path before
the call is answered.
Note:

The parameter is applicable only to the Gateway application.

FXO interfaces: The feature is applicable only to one-stage dialing
(FXO).

Digital interfaces: To activate the feature, set the
EnableDSPIPMDetectors parameter to 1.

Digital interfaces: The parameter is applicable only when the
protocol type is CAS.
