Parameter Description
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
CLI: isdn-bits-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 = (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).
[ISDNInCallsBehavior_x]
Same as the description for the parameter ISDNInCallsBehavior,
but per trunk (i.e., where x denotes the Trunk ID).
Web/EMS: Q.931 Layer
Response Behavior
CLI: isdn-bits-ns-behavior
[ISDNIBehavior]
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
