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.
Web/EMS: Incoming Calls
Behavior
[ISDNInCallsBehavior]
Version 6.6
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 313.
Allows the device to ignore ISDN Disconnect messages with PI 1
or 8.

[1] = The call (in connected state) is not released if a Q.931
Disconnect with PI (PI = 1 or 8) message is received during
the call.

[0] = (Default) The call is disconnected.
Determines whether and which Progress Indicator (PI) information
element (IE) is added to the sent ISDN Setup message. Some
ISDN protocols such as NI-2 or Euro ISDN can optionally contain
PI = 1 or PI = 3 in the Setup message.

[0] = PI is not added (default).

[1] = PI 1 is added to a sent ISDN Setup message - call is not
end-to-end ISDN.

[3] = PI 3 is added to a sent ISDN Setup message - calling
equipment is not ISDN.
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 = (Default) 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 = The Setup Ack message is sent
by the SIP Gateway application layer and not automatically by
the PSTN stack. By default, this bit is set.

[8192] CHAN ID IN CALL PROC = The device sends Channel
ID in a Q.931 Call Proceeding message.

[65536] PROGR IND IN SETUP ACK = The device includes
Progress Indicator (PI=8) in Setup Ack message if an empty
called number is received in an incoming Setup message. This
option is applicable to the overlap dialing mode. The device
also plays a dial tone (for TimeForDialTone) until the next
