Parameter
[IP2TelTaggingDestDialPlanInde
x]
[EnableETSIDiversion]
Web: Add CIC
[AddCicAsPrefix]
Version 6.4
Determines the Dial Plan index in the external Dial Plan file
(.dat) in which string labels ("tags") are defined for tagging
incoming IP-to-Tel calls. The special "tag" is added as a prefix to
the called party number, and then the Inbound IP Routing Table'
uses this "tag" instead of the original prefix. Manipulation is then
performed (after routing) in the Manipulation table which strips
the "tag" characters before sending the call to the endpoint.
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).
The routing label can be up to 9 (text) characters.
Notes:

The routing must be configured to be performed before
manipulation.

For more information on this feature, see Dial Plan Prefix
Tags for IP-to-Tel Routing on page 282.
Determines the method in which the Redirect Number is sent to
the Tel side.

[0] = Q.931 Redirecting Number Information Element (IE)
(default)

[1] = ETSI DivertingLegInformation2 in a Facility IE
Determines whether to add the Carrier Identification Code (CIC)
as a prefix to the destination phone number for IP-to-Tel calls.

[0] No (default)

[1] Yes
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.
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.
