ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different switches/PBXs by different vendors. Several
implementations may vary slightly from the specification. Therefore, to provide a flexible interface
that supports these ISDN variants, the ISDN behavior parameters can be used.

Behavior
[ISDNInCallsBehavior]
Version 6.8
Trunks that belong to the same NFAS group have the same
number. With NFAS, you can use a single D-channel to control
multiple PRI interfaces.
Notes:

For this parameter to take effect, a device reset is required.

This parameter is applicable only to T1 ISDN protocols.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.

For more information on NFAS, see ''ISDN Non-Facility
Associated Signaling (NFAS)'' on page 378.
Defines primary, backup (optional), and B-channels only, per
trunk.

[0] PRIMARY= (Default) Primary Trunk - contains a D-
channel that is used for signaling.

[1] BACKUP = Backup Trunk - contains a backup D-channel
that is used if the primary D-channel fails.

[2] NFAS = NFAS Trunk - contains only 24 B-channels,
without a signaling D-channel.
Notes:

This parameter is applicable only to T1 ISDN protocols.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
Defines a different Interface ID per T1 trunk.
The valid range is 0 to 100. The default interface ID equals the
trunk's ID.
Notes:

To set the NFAS interface ID, configure ISDNIBehavior_x to
include '512' feature per T1 trunk.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.

For more information on NFAS, see ''ISDN Non-Facility
Associated Signaling (NFAS)'' on page 378.
Determines the bit-field used to determine several behavior
options that influence how the ISDN Stack INCOMING calls
behave.

[32] DATA CONN RS = The device automatically sends a
Q.931 Connect (answer) message on incoming Tel calls
(Q.931 Setup).

[64] VOICE CONN RS = The device sends a Connect
(answer) message on incoming Tel calls.

[2048] CHAN ID IN FIRST RS = The device sends Channel
ID in the first response to an incoming Q.931 Call Setup
message. Otherwise, the Channel ID is sent only if the device
requires changing the proposed Channel ID.

[4096] USER SETUP ACK = (Default) The Setup Ack
message is sent by the SIP Gateway application layer and
not automatically by the PSTN stack.
