User's Manual 54. Configuration Parameters Reference
Version 6.8 845 Mediant 500 E-SBC
Parameter Description
number, where 0 is Trunk 1.
Web: B-Channel Negotiation
EMS: B-Channel Negotiation
For Trunk Mode
[BChannelNegotiationForTru
nk_x]
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.
CLI: snd-isdn-ser-aftr-restart
[SendISDNServiceAfterResta
rt]
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
EMS: Support Redirect
InFacility
[SupportRedirectInFacility]
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.
CLI: call-re-rte-mode
[CallReroutingMode]
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.
EMS: Enable CIC
[EnableCIC]
Determines whether the Carrier Identification Code (CIC) is relayed
to ISDN.

[0] = (Default) Do not relay the Carrier Identification Code (CIC)
to ISDN.

[1] = CIC is relayed to the ISDN in Transit Network Selection
