Parameter Description
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 Trunk Group 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 = Incoming ISDN calls are delayed until a
CNG tone detection or timeout, set by the FaxReroutingDelay
parameter. If the EnableComfortTone parameter is set to 1, a
Q.931 Progress message with Protocol Discriminator set to 1 is
sent to the PSTN and a comfort tone is played accordingly to the
PSTN. When the timeout expires, the device sends an INVITE to
a specific IP Group or to a fax server, according to the Tel-to-IP
Routing table rules.
 [3] Connect and Delay = Incoming ISDN calls are delayed until a
CNG tone detection or timeout, set by the FaxReroutingDelay
parameter. A Q.931 Connect message is sent to the PSTN. If the
EnableComfortTone parameter is set to 1, a comfort tone is
played to the PSTN. When the timeout expires, the device sends
an INVITE to a specific IP Group or to a fax server according to
the Tel-to-IP Routing table rules.
Note: The parameter has replaced the EnableFaxRerouting
parameter. For backward compatibility, the EnableFaxRerouting
parameter set to 1 is equivalent to the FaxReroutingMode parameter
set to 1.
[FaxReroutingDelay] Defines the maximum time interval (in seconds) that the device waits
for CNG detection before re-routing calls identified as fax calls to fax
