Considerations and Constraints
Printing system programming reports has a higher priority than printing SMDR
reports. SMDR records are queued until programming report printing is
completed. Records are also queued if the printer is turned off, disconnected,
runs out of paper, or if a paper jam occurs. Up to 100 SMDR records can be
queued. SMDR records generated after maximum capacity is exceeded may be
lost, since only the newest 100 records are retained.
System time and date must be set correctly to print accurate SMDR reports.
The maximum digits recorded in the CALLED NUMBER field is 15.
When the number included in the CALLED NUMBER field contains both an
equal access code and a country code for an overseas call, the maximum digits
recorded may not provide enough information for call accounting software to
process the call and supply cost data.
Call information can be recorded for incoming and outgoing calls (factory
setting) or for outgoing calls only. If SMDR is set to record outgoing calls only,
an account code cannot be entered for incoming calls.
Inside calls are not recorded on SMDR reports.
When a user joins a call on a shared line and continues on the call after the
originator drops off, SMDR records the total duration of the call, up through the
time the last person hangs up.
If a person selects a line and cannot complete the call (for example, due to
restrictions), yet is on the line for more than the programmed call duration, an
SMDR record is created, even though a call was never made on that line.
In the event of a power failure, any calls in progress and the SMDR records for
those calls are lost.
In Release 2.1 and later, an SMDR record is not generated for calls made to
loudspeaker paging ports.
Telephone Differences
Queued Call Consoles
When a QCC system operator arranges a 3-participant conference call (the
system operator and two other participants) and presses the Release button,
the QCC system operator is released from the call, but the other two
participants remain connected. However, the QCC operator's extension remains
on the SMDR record.
