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.
Enables re-routing of 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 prefix string "FAX" is appended to the destination
number before routing and manipulation. If you enter the
string value, "FAX" as the destination number in the
Outbound IP Routing table, the routing rule is used to route
the call and the destination number manipulation mechanism
is used to remove the "FAX" prefix, if required. Note that the
"FAX" prefix string in routing and manipulation tables is
case-sensitive.
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

[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
Outbound IP Routing table rules. This option is applicable
only to ISDN.

[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
