IP Line Description, Installation and Maintenance
CDR
No ACF-specific information is added to the Call Detail Record (CDR)
records.
In the case of Call Server failure, the CDR records for the call before the
failure occurred are lost. CDR is restarted as the active IP Phone reregisters.
Therefore, the records are generated only for the “post-failure” period of time.
In the case of the LTPS or network failure, CDR continues. The CDR is then
stopped only if:
• the Call Server supervisory timer expires
• the IP Phone is idle when it reregisters
• the active IP Phone reregisters and then the call is released
The records include the failover time as well. This means that the user may
be “under-charged” in case of Call Server failure and “over-charged” in a
case of LTPS/network failure.
CallPilot
ACF considers CallPilot to be a TDM resource and interaction of an IP Phone
with CallPilot as an IP/TDM call. See “IP/TDM calls” on page 87 and
Table 13: “ACF behaviors” on page 79.
Example: IP Phone A calls telephone B and is redirected to CallPilot on no
answer. The IP/TDM call is established between the IP Phone A and
CallPilot.
The media session between CallPilot and the IP Phone survives any type of
failures except a Call Server cold start.
Note that during any failure, user input is not passed to CallPilot. The user
must resume entering responses after the IP Phone reregisters.
