Mediant 500L MSBR
Parameter Description
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)
= 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
(TNS) IE.
If enabled, the CIC code (received in an INVITE Request-URI) is
included in a TNS IE in the ISDN Setup message.
For example: INVITE sip:555666;cic=2345@100.2.3.4 sip/2.0.
Notes:
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.
Web/EMS: AoC Support
[EnableAOC]
Enables the interworking of ISDN Advice of Charge (AOC)
messages to SIP.
[0] Disable (default)
[1] Enable
For more information on AOC, see ''Advice of Charge Services for
Euro ISDN'' on page 479.
