[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
configure voip > sip-definition

[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.
configure voip > interface e1-
t1|bri > 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 the parameter is enabled, ensure that you configure in
the IP-to-Tel 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.
[EnableCIC] Enables the relay of the Carrier Identification Code (CIC) to the ISDN.
 [0] = (Default) Disabled - CIC is not relayed to the ISDN.
 [1] = Enabled - CIC (received in the INVITE Request-URI) is
relayed to the ISDN in the Transit Network Selection (TNS) IE of
the Setup message. For example: INVITE
sip:555666;cic=2345@100.2.3.4 sip/2.0.
Note:
 This feature is supported only for SIP-to-ISDN calls.
 The parameter AddCicAsPrefix can be used to add the CIC as a
prefix to the destination phone number for routing IP-to-Tel calls.
