[0] Disable = Disable (default)

User Agent Client (UAC) Behavior:
Initial request: The History-Info header is equal to the Request URI. If a
PSTN Redirect number is received, it is added as an additional History-
Info header with an appropriate reason.
Upon receiving the final failure response, the device copies the History-
Info as is, adds the reason of the failure response to the last entry, and
concatenates a new destination to it (if an additional request is sent).
The order of the reasons is as follows:
1. Q.850 Reason
2. SIP Reason
3. SIP Response code
Upon receiving the final response (success or failure), the device
searches for a Redirect reason in the History-Info (i.e., 3xx/4xx SIP
reason). If found, it is passed to ISDN according to the following table:
SIP Reason Code
302 - Moved Temporarily
408 - Request Timeout
480 - Temporarily Unavailable
487 - Request Terminated
486 - Busy Here
600 - Busy Everywhere
If history reason is a Q.850 reason, it is translated to the SIP reason
(according to the SIP-ISDN tables) and then to ISDN Redirect reason
according to the table above.
User Agent Server (UAS) Behavior:
The History-Info header is sent only in the final response.
Upon receiving a request with History-Info, the UAS checks the policy in
the request. If 'session', 'header', or 'history' policy tag is found, the
(final) response is sent without History-Info; otherwise, it is copied from
the request.
Determines the use of Tel Source Number and Display Name for Tel-to-IP
calls.
[0] No = If a Tel Display Name is received, the Tel Source Number is
used as the IP Source Number and the Tel Display Name is used as the
IP Display Name. If no Display Name is received from the Tel side, the
IP Display Name remains empty (default).
[1] Yes = If a Tel Display Name is received, the Tel Source Number is
used as the IP Source Number and the Tel Display Name is used as the
IP Display Name. If no Display Name is received from the Tel side, the
Tel Source Number is used as the IP Source Number and also as the IP
Display Name.
[2] Overwrite = The Tel Source Number is used as the IP Source
Number and also as the IP Display Name (even if the received Tel
Display Name is not empty).
