Parameter
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.

User's Manual

The PSTN protocol type (ProtocolType) is configured as
Euro 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
called number digits are received. By default, this is bit is set.

[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: 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).
