User Agent Client (UAC) Behavior:
â– 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.
â– 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
â– 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 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
â– 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:
â– The History-Info header is sent only in the final response.
