SIP User's Manual 3. Web-Based Management
Parameter Description
Enable History-Info
Header
[EnableHistoryInfo]
Enables usage of the History-Info header.
[0] Disable = Disable (default)
[1] Enable = 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:
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:
SIP Reason Code ISDN Redirecting Reason
302 - Moved Temporarily Call Forward Universal (CFU)
408 - Request Timeout Call Forward No Answer (CFNA)
480 - Temporarily Unavailable
487 - Request Terminated
486 - Busy Here Call Forward Busy (CFB)
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.
Use Source Number as
Display Name
[UseSourceNumberAsDi
splayName]
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).
