Disconnect Call on Detection of Busy Tone

Version 7.2
reorder tone is played, the device rejects the call.
Note:

If the parameter is disabled and the PSTN side remains in off-
hook state after the IP call ends the call, the device releases
the call after 60 seconds.

A special CAS table can be used to report call status events
(Active/Idle) to the PSTN side during Cut Through mode (see
Configuring CAS State Machines on page 451).

The corresponding global parameter is DigitalCutThrough.
Defines call priority handling.

[0] Disable (default).

[1] MLPP = Enables MLPP Priority Call handling. MLPP
prioritizes call handling whereby the relative importance of
various kinds of communications is strictly defined, allowing
higher precedence communication at the expense of lower
precedence communications. Higher priority calls override
less priority calls when, for example, congestion occurs in a
network.

[2] Emergency = Enables Preemption of IP-to-Tel E911
emergency calls. If the device receives an E911 call and
there are unavailable channels to receive the call, the device
terminates one of the channel calls and sends the E911 call
to that channel. The preemption is done only on a channel
belonging to the same Trunk Group for which the E911 call
was initially destined and if the channel select mode
(configured by the ChannelSelectMode parameter) is set to
other than By Dest Phone Number (0). The preemption is
done only if the incoming IP-to-Tel call is identified as an
emergency call. The device identifies emergency calls by one
of the following:

The destination number of the IP call matches one of the
numbers configured by the EmergencyNumbers
parameter. (For E911, you must configure the parameter
to "911".)

The incoming SIP INVITE message contains the
"emergency" value in the Priority header.
Note:

The parameter is applicable to FXS/FXO, ISDN and CAS.

For FXO interfaces, the preemption is done only on existing
IP-to-Tel calls. In other words, if all the current FXO channels
are busy with calls that were initiated by the FXO (i.e., Tel-to-
IP calls), new incoming emergency IP-to-Tel calls are
rejected.

For more information, see ''Pre-empting Existing Call for E911
IP-to-Tel Call'' on page 560.

The corresponding global parameter is CallPriorityMode.
Enables the device to disconnect the call upon detection of a
busy or reorder (fast busy) tone.

[0] Disable

[1] Enable (Default)
