Version 6.8
The valid value is 1 to 360,000. The default is 6,000.
Note: This parameter is applicable only to Digital interfaces.
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.

[0] No = (Default) The device sends a SIP 200 OK only after it
completes dialing to the Tel side.
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.
Notes:

FXO interfaces: This feature is applicable only to one-stage
dialing (FXO).

Digital interfaces: To activate this feature, set the
EnableDSPIPMDetectors parameter to 1.

Digital interfaces: This feature is applicable only when the
protocol type is CAS.
Defines the maximum duration (in minutes) of a call. If this
duration is reached, the device terminates the call. This feature is
useful for ensuring available resources for new calls, by ensuring
calls are properly terminated.
The valid range is 0 to 35,791. The default is 0 (i.e., no limitation).
Defines the minimum call duration (in seconds) for the Tel side. If
an established call is terminated by the IP side before this
duration expires, the device terminates the call with the IP side,
but delays the termination toward the Tel side until this timeout
expires.
The valid value range is 0 to 10 seconds, where 0 (default)
disables this feature.
For example: assume the minimum call duration is set to 10
seconds and an IP phone hangs up a call established with a BRI
phone after 2 seconds. As the call duration is less than the
minimum call duration, the device does not disconnect the call on
the Tel side. However, it sends a SIP 200 OK immediately upon
receipt of the BYE to disconnect from the IP phone. The call is
disconnected from the Tel side only when the call duration is
greater than or equal to the minimum call duration.
Notes:

This parameter is applicable to IP-to-Tel and Tel-to-IP calls.

This parameter is applicable only to ISDN and CAS protocols.
