Version 6.8 867 Mediant 500 E-SBC
Parameter Description
Note: This parameter is applicable only to digital interfaces.
Web: IP to Tel Tagging Source Dial
Plan Index
CLI: configure voip/gw routing general-
setting/ip-to-tel-tagging-src
[IP2TelTaggingSourceDialPlanIndex] Defines the Dial Plan index in the Dial Plan file for calling
prefix tags for representing calling number prefixes in
Inbound Routing rules.
The valid values are 0 to 7, where 0 denotes PLAN1, 1
denotes PLAN2, and so on. The default is -1 (i.e., no dial
plan file used).
For more information on this feature, see Dial Plan Prefix
Tags for IP-to-Tel Routing on page
559 .
Note: This parameter is applicable only to digital interfaces.
CLI: etsi-diversion
[EnableETSIDiversion] Determines the method in which the Redirect Number is
sent to the Tel side.

[0] = (Default) Q.931 Redirecting Number Information
Element (IE).

[1] = ETSI DivertingLegInformation2 in a Facility IE.
Web: Add CIC
CLI: add-cic
[AddCicAsPrefix]
Determines whether to add the Carrier Identification Code
(CIC) as a prefix to the destination phone number for IP-to-
Tel calls. When this parameter is enabled, the 'cic'
parameter in the incoming SIP INVITE can be used for IP-to-
Tel routing decisions. It routes the call to the appropriate
Trunk Group based on this parameter's value.

[0] No (default)

[1] Yes
For digital interfaces: The SIP 'cic' parameter enables the
transmission of the 'cic' parameter from the SIP network to
the ISDN. The 'cic' parameter is a three- or four-digit code
used in routing tables to identify the network that serves the
remote user when a call is routed over many different
networks. The 'cic' parameter is carried in the SIP INVITE
and maps to the ISDN Transit Network Selection Information
Element (TNS IE) in the outgoing ISDN Setup message (if
the EnableCIC parameter is set to 1). The TNS IE identifies
the requested transportation networks and allows different
providers equal access support, based on customer choice.
For example, as a result of receiving the below INVITE, the
destination number after number manipulation is
cic+167895550001:
INVITE
sip:5550001;cic=+16789@172.18.202.60:5060;user=phone
SIP/2.0
Note: After the cic prefix is added, the Inbound IP Routing
table can be used to route this call to a specific Trunk Group.
The Destination Number IP to Tel Manipulation table must
be used to remove this prefix before placing the call to the
ISDN.
[FaxReroutingMode] Enables the re-routing of incoming Tel-to-IP calls that are
identified as fax calls. If a CNG tone is detected on the Tel
side of a Tel-to-IP call, the device adds the string, "FAX" as
a prefix to the destination number before routing and
manipulation. A routing rule in the Outbound IP Routing
table having the value "FAX" (case-sensitive) as the
destination number is then used to re-route the call to a fax
destination and the destination number manipulation
