Call Routing logic on Cisco UBE using the History-info Header

The history-info header has the call or dialog history information. The receiving application uses the history-info header information to determine how and why the call has reached it. SIP IOS GW does not utilize this information in History-Info header. The information stored in the History-Info headers can be used to bypass the dial-peers that were already tried during the course of a call, ensuring that the call is not being redirected again to the same target. The called-numbers and host portion of request URI in History-Info headers will be compared with the matching dial-peers, if incase the comparison succeeds, then those dial-peers will be bypassed.

This section contains the following procedures:
