SIP User's Manual 842 Document #: LTRT-12804
Mediant 800 MSBG
Parameter Description
first checks the 'Outbound IP Routing Table' before making a
call through the Proxy. If the number is not allowed (i.e., number
isn't listed in the table or a call restriction routing rule of IP
address 0.0.0.0 is applied), the call is released.
Note: When no Proxy is used, this parameter must be disabled
and filtering is according to the 'Outbound IP Routing Table'.
[IP2TelTaggingDestDialPlanInde
x]
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:
This parameter is applicable only to digital interfaces.
The routing must be configured to be performed before
manipulation.
For a detailed description of this feature, see Dial Plan Prefix
Tags for IP-to-Tel Routing on page 418.
[EnableETSIDiversion]
Defines 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
Web: 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.
[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 Hunt 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
