User's Manual

[1] Yes = 'user=phone' string is part of the From and Contact
headers.

Preferred-Identity headers.

[0] Disable = (Default) 'sip:'

[1] Enable = 'tel:'
Defines the time (in seconds) that the device waits for a 200 OK
response from the called party (IP side) after sending an INVITE
message. If the timer expires, the call is released.
The valid range is 0 to 3600. The default is 180.
Enables Remote-Party-Identity headers for calling and called numbers
for Tel-to-IP calls.

[0] Disable (default).

[1] Enable = Remote-Party-Identity headers are generated in SIP
INVITE messages for both called and calling numbers.
Enables usage of the History-Info header.

[0] Disable (default)

[1] Enable
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:
a. Q.850 Reason
b. SIP Reason
c. 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 a 'session', 'header', or 'history' policy tag is
found, the (final) response is sent without History-Info; otherwise, it
