User's Manual
outgoing calls to PSTN, per trunk. This timer is used between the
time that an ISDN Setup message is sent to the Tel side (IP-to-Tel
call establishment) and a Connect message is received. If Alerting
is received, the timer is restarted.
The range is 1 to 600. The default is 180.
Note: The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
Determines the ISDN B-channel negotiation mode, per trunk.

[-1] Not Configured = (Default) Use per device configuration of
the BChannelNegotiation parameter.

[0] Preferred.

[1] Exclusive.

[2] Any.
Notes:

This parameter is applicable to ISDN protocols.

The option Any is only applicable if TerminationSide is set to 0
(i.e., User side).

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.
Enables the device to send an ISDN SERVice message per trunk
upon device reset. The messsage (transmitted on the trunk's D-
channel) indicates the availability of the trunk's B-channels (i.e.,
trunk in service).

[0] = Disable (default)

[0] = Enable
Determines whether the Redirect Number is retrieved from the
Facility IE.

[0] = (Default) Not supported.

[1] = Supports partial retrieval of Redirect Number (number only)
from the Facility IE in ISDN Setup messages. This is applicable
to Redirect Number according to ECMA-173 Call Diversion
Supplementary Services.
Note: To enable this feature, the parameter
ISDNDuplicateQ931BuffMode must be set to 1.
Determines whether ISDN call rerouting (call forward) is performed
by the PSTN instead of by the SIP side. This call forwarding is
based on Call Deflection for Euro ISDN (ETS-300-207-1) and QSIG
(ETSI TS 102 393).

[0] Disable (default).

[1] Enable = Enables ISDN call rerouting. When the device
sends the INVITE message to the remote SIP entity and
receives a SIP 302 response with a Contact header containing a
URI host name that is the same as the device's IP address, the
device sends a Facility message with a Call Rerouting invoke
method to the ISDN and waits for the PSTN side to disconnect
the call.
Note: When this parameter is enabled, ensure that you configure in
the Inbound IP Routing Table (PSTNPrefix ini file parameter) a rule
to route the redirected call (using the user part from the 302 Contact
header) to the same Trunk Group from where the incoming Tel-to-
IP call was received.
