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).
Same as the description for the parameter
ISDNInCallsBehavior, but per trunk (i.e., where x denotes the
Trunk ID).
Bit-field used to determine several behavior options that
influence the behaviour of the Q.931 protocol.

[0] = Disable (default).

[1] NO STATUS ON UNKNOWN IE = Q.931 Status
message isn't sent if Q.931 received message contains an
unknown/unrecognized IE. By default, the Status message
is sent.
Note: This value is applicable only to ISDN variants in
which sending of Status message is optional.

[2] NO STATUS ON INV OP IE = Q.931 Status message
isn't sent if an optional IE with invalid content is received.
By default, the Status message is sent.
Note: This option is applicable only to ISDN variants in
which sending of Status message is optional.

[4] ACCEPT UNKNOWN FAC IE = Accepts
unknown/unrecognized Facility IE. Otherwise, the Q.931
message that contains the unknown Facility IE is rejected
