Description
Enables usage of the History-Info header.
Valid options include:
0 = Disable (default)
1 = Enable
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 gateway 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:
- Q.850 Reason
- SIP Reason
- SIP Response code
Upon receiving the final (success or failure) response, the gateway 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.
UAS Behavior:
History-Info is sent in the final response only.
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.
Applicable to Tel IP calls.
No [0] = The Tel Source Number is used as the IP Source Number and the Tel
Display Name is used as the IP Display Name (if Tel Display Name is received). If
no Display Name is received from the Tel side, the IP Display Name remains
empty (default).
Yes [1] = 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.
Overwrite [2] = 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).
