Call Failure Scenarios
The following are some potential call failure scenarios. Note that these scenarios make the following assumptions:
If a Callback-Id AVP is not received in the final DEA message during the first authentication, the session setup
is terminated with appropriate error logs being generated.
A DNS server provides IP addresses to the MS.
Unless stated otherwise, the starting condition for these scenarios is that the MS established an IPSec session
with the primary PDIF and registered with the MIP HA.
MS Power-Down or Failure
If the MS powers down or fails without first deleting the IPSec session with the PDIF, the PDIF has no way to know
this if no DPD is configured to notify the MS.
this if no DPD is configured to notify the MS.
The PDIF tears down the IPSec session to the MS when the IPSec session timer expires or when the inactivity timer
expires (whichever occurs first). When the MS comes back on line, it attempts to establish a new IPSec session with the
PDIF. If the MS attempts to establish this new session before the old one times out, the PDIF detects that the IMSI of
the MS is already registered to another IPSec session. The PDIF establishes the new session and then clears the old
session, but only if the new IPSec session is successfully established.

However, with DPD configured to be sent to the MS, the PDIF actively deletes the IPSec session. If the MS attempts to
