[FaxReroutingDelay]
Version 6.8
51. Configuration Parameters Reference
The Destination Number IP to Tel Manipulation table must
be used to remove this prefix before placing the call to the
ISDN.
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 Outbound 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 Outbound IP
Routing table rules. 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).
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 = (Applicable only to ISDN).
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 Outbound IP
Routing table rules. This option is applicable only to
ISDN.
Note: This parameter has replaced the EnableFaxRerouting
parameter. For backward compatibility, the
EnableFaxRerouting parameter set to 1 is equivalent to the
FaxReroutingMode parameter set to 1.
Defines the maximum time interval (in seconds) that the
device waits for CNG detection before re-routing calls
identified as fax calls to fax destinations (terminating fax
machine).
The valid value range is 1-10. The default is 5.
