[AddCicAsPrefix]
Determines whether to add the Carrier Identification Code
(CIC) as a prefix to the destination phone number for IP-to-Tel
calls. When the 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 the 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 IP-to-Tel 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 Tel-to-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 mechanism is used
to remove the "FAX" prefix before sending the fax, if required.
If the initial INVITE used to establish the voice call (not fax)
was already sent, a CANCEL (if not connected yet) or a BYE
(if already connected) is sent to release the voice call.
 [0] Disable (default)
 [1] Rerouting without Delay = Upon detection of a CNG
tone, the device immediately releases the call of the initial
INVITE and then sends a new INVITE to a specific IP
Group or fax server according to the Tel-to-IP Routing
table. To enable this feature, set the CNGDetectorMode
parameter to 2 and the IsFaxUsed parameter to 1, 2, or 3.
 [2] Progress and Delay = (Applicable only to ISDN)
