Mediant 3000
Parameter Description
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:

To activate this feature, set the EnableDSPIPMDetectors parameter
to 1.

This feature is applicable only when the protocol type is CAS.
Web/EMS: Max Call
Duration (min)
[MaxCallDuration]
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).
[MinCallDuration]
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.
Web: Send Digit Pattern
on Connect
EMS: Connect Code
[TelConnectCode]
Defines a digit pattern to send to the Tel side after a SIP 200 OK is
received from the IP side. The digit pattern is a user-defined DTMF
sequence that is used to indicate an answer signal (e.g., for billing).
The valid range is 1 to 8 characters.
Note: This parameter is applicable to CAS.
Web: Disconnect on
Broken Connection
EMS: Disconnect Calls
on Broken Connection
[DisconnectOnBroken
Connection]
Determines whether the device releases the call if RTP packets are not
received within a user-defined timeout.

[0] No

[1] Yes (default)
Notes:

The timeout is configured by the BrokenConnectionEventTimeout
parameter.

This feature is applicable only if the RTP session is used without
Silence Compression. If Silence Compression is enabled, the device
doesn't detect a broken RTP connection.

During a call, if the source IP address (from where the RTP packets
are received) is changed without notifying the device, the device
filters these RTP packets. To overcome this, set the
DisconnectOnBrokenConnection parameter to 0; the device doesn't
detect RTP packets arriving from the original source IP address and
switches (after 300 msec) to the RTP packets arriving from the new
source IP address.

This parameter can also be configured in an IP Profile.
