ISDN Transfer Capabilities

ISDN SETUP messages. The ID in the ini file parameter depicts the trunk
number.
 [-1] Not Configured
 [0] Audio 3.1 = Audio (default).
 [1] Speech = Speech.
 [2] Data = Data.
 Audio 7 = Currently not supported.

ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different Switches / PBXs by different vendors. Several
implementations vary a little from the specification. Therefore, to provide a flexible interface that
supports these ISDN variants, the ISDN behavior parameters are used.
To configure the different behavior bits in the Web interface, you can either enter the exact
hexadecimal bits value in the field to the right of the relevant parameter, or directly configure each bit
field by completing the following steps:
1. Click the arrow button to the right of the relevant parameter; the relevant behavior page
appears.
2. Modify each bit field according to your requirements.
3. Click the Submit button to save your changes.
Q.931 Layer Response
Behavior
[ISDNIBehavior]
Bit-field used to determine several behavior options that influence the
behaviour of the Q.931 protocol. To select the options, click the arrow
button, and then for each required option, select 1 to enable. The default
is 0 (i.e., disable).

decoding is performed on Facility IE.
 [128] SEND USER CONNECT ACK = Connect ACK message is sent

 [2048] ALWAYS EXPLICIT = Always set the Channel Identification IE
to explicit Interface ID, even if the B-channel is on the same trunk as
