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:
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.
