7.1.4. Special Features 
- Data is always entered in the Paying_Party, Calling_Party, and Destination_Party
fields in the charge detail record. In contrast, the Called_Party field
is not always supplied with data. Data is entered in the Transferring-Party
field in the event of call transfer. The Mobile_User_Calling and Key_Line_Used
CM (PIN /KEY system) fields are feature-dependent.
- If CDRE is active, the entries for cost distribution on the AC and
for CHESEs in the AMO GEFE are ignored. A separate CDB is generated
for each call segment.
- When CDRE is active, the off-hook signal starts the call detail recording
irrespective of the entry in ZAND (answer or end of dial).
- The AMO DEFPP is only applicable to an incoming and outgoing connection.
The entries are ignored for an internal connection.
- A customer-specific calling number should be entered for each trunk
or attendant in the AMO TLZO. If you do not enter this number, a default
calling number (999999) is entered in the record.
- In the AMO KNMAT, MODCON parameter entries are ignored for the virtual
node number CDR.
- The COT parameter AOCC:
- should always be set in systems with V2.0 or later with Cornet NQ, ECMA,
and QSIG.
- in external systems with ECMA/QSIG should be checked to ensure that
the parameter is interpreted correctly in the remote system. Display
information is lost in the event of incorrect interpretation.
- should be set if you want charge information to be sent to the connected
system.
- must not be set for other protocols, such as, DSS1, DPNSS, and DASS
because the remote system cannot work with the protocol messages that
this would generate, which could result in the OpenScape 4000 incorrectly
turning off the display information.
- The COT parameter ICZO only activates the incoming call detail recording
on the trunk.
- The ICZL has no function at this time because no carrier currently
sends charge information for incoming calls.
- In the AMO PERSI, COPIN specifies which calling number is sent to
the call detail recording module during identification (station or mobile).
