Parameter
Mediant 800 Gateway & E-SBC | User's Manual
Description
Defines the maximum duration (in minutes) per
Gateway 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, where 0 is unlimited
duration. The default is 0.
Note: The parameter is applicable only to the
Gateway application.
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.
Note:
■ The parameter is applicable only to the Gateway
application.
■ The parameter is applicable to IP-to-Tel and Tel-
to-IP calls.
■ The parameter is applicable only to ISDN and
CAS protocols.
Determines whether the device disconnects a call
when a dial tone is detected from the PBX.
■ [0] Disable = (Default) Call is not released.
■ [1] Enable = Call is released if a dial tone is
detected on the device's FXO port.
Note:
■ The parameter is applicable only to FXO
interfaces.
■ This option is in addition to the mechanism that
disconnects a call when either busy or reorder
tones are detected.
