Note: Regardless of the ForkingHandlingMode value, once a SIP
200 OK response is received, the device uses the RTP information
and re-opens the voice stream, if necessary.
Enables or disables the usage of the SIP Reason header.

[0] Disable.

[1] Enable (default).
Determines whether all TCP/TLS connections are set as persistent
and therefore, not released.

[0] = Disable (default) - all TCP connections (except those that
are set to a proxy IP) are released if not used by any SIP
dialog\transaction.

[1] = Enable - TCP connections to all destinations are persistent
and not released unless the device reaches 70% of its maximum
TCP resources.
While trying to send a SIP message connection, reuse policy
determines whether alive connections to the specific destination are
re-used.
Persistent TCP connection ensures less network traffic due to fewer
setting up and tearing down of TCP connections and reduced
latency on subsequent requests due to avoidance of initial TCP
handshake. For TLS, persistent connection may reduce the number
of costly TLS handshakes to establish security associations, in
addition to the initial TCP connection set up.
Enables or disables re-routing of Tel-to-IP calls that are identified as
fax calls.

[0] Disable = Disabled (default).

[1] Enable = Enabled.
If a CNG tone is detected on the Tel side of a Tel-to-IP call, the
prefix "FAX" is appended to the destination number before routing
and manipulations. An entry of "FAX" as the destination number in
the 'Tel-to-IP Routing' table is then used to route the call, and the
destination number manipulation mechanism is used to remove the
"FAX" prefix, 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 tear down the voice call.
Notes:

To enable this feature, set CNGDetectorMode to 2, and
IsFaxUsed to 1, 2, or 3.

The "FAX" prefix in routing and manipulation tables is case
sensitive.
Assigns a name to the device (e.g., 'gateway1.com'). Ensure that the
name you choose is the one with which the Proxy is configured to
identify the device.
Note: If specified, the device name is used as the host part of the
SIP URI in the From header. If not specified, the device's IP address
is used instead (default).
