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.
