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.
Incoming Calls Behavior

[ISDNInCallsBehavior]
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. If not set, 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.

[8192] CHAN ID IN CALL PROC = The device sends Channel
ID in a Q.931 Call Proceeding message.

[65536] PROGR IND IN SETUP ACK = (Default) 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 called number digits are received.

[2147483648] USER SCREEN INDICATOR = When the
device receives two Calling Number IE's in the Setup
message, the device, by default, uses only one of the numbers
according to the following:

Network provided, Network provided - the first calling
number is used

Network provided, User provided: the first one is used

User provided, Network provided: the second one is used

User provided, user provided: the first one is used
When this bit is configured, the device behaves as follows:

Network provided, Network provided: the first calling
number is used

Network provided, User provided: the second one is used

User provided, Network provided: the first one is used

User provided, user provided: the first one is used
Note:

In the Web interface, the parameter displays the summation of
the enabled optional bit values, in hex format. For example,
the default value is 0x11000 (69632 in decimal), which is the
summation of the two bit options, USER SETUP ACK
(0x01000 or 4096 in decimal) and PROGR IND IN SETUP
ACK (0x10000 or 65536 in decimal) that are enabled by
default (i.e., 4096 + 65536 = 69632).

When using the ini file to configure the device to support
several ISDNInCallsBehavior features, enter a summation of
the individual feature values. For example, to support both
[2048] and [65536] features, set ISDNInCallsBehavior = 67584
(i.e., 2048 + 65536).
[ISDNInCallsBehavior_x]
