When a QCC system operator arranges a three-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 system operator's extension remains on the
SMDR record.
If a multiline telephone user presses the Recall button to get a new dial tone, the
SMDR timing is stopped for the previous call and timing begins for a new call.
Remote Access calls are recorded only if SMDR is programmed to track
incoming calls. If a barrier code is entered, the barrier code number (00-16)
appears in the "Account" field of the report. If the caller uses Remote Access to
dial an extension and the call is answered, the station's extension is shown in
the "Station Extension" field. If the call is not answered at the extension, the
"Station Extension" field is blank.
If the caller uses Remote Access to dial out on a line or trunk, the "Station
Extension" field is blank on the first SMDR record and a second record is
generated for the outgoing call.
A Remote Access user cannot enter account codes. However, if a Remote
Access user calls an inside extension and the person at that extension enters an
account code, the code overrides the barrier code (00-16) printed in the
Account column.
All numbers dialed on an outside call by using Saved Number Dial are recorded
on the SMDR report.
When Personal Speed Dial or System Speed Dial is used to dial an outgoing
call, the actual digits dialed by the system appear on the report. However, when
a marked System Speed Dial number is used, the Speed Dial code prints rather
than the digits dialed.
In the Hybrid/PBX mode, when a call is made with a Shared System Access
button, the SMDR report records the extension that the call was made from and
not the principal station extension number.
The extension number for the station that hangs up on an incoming outside call
is shown in the "Station Extension" field of the SMDR report regardless of how
many times the call is transferred. For outgoing outside calls, the station
extension that dialed the call is shown on the SMDR report even if the call is
later transferred to another extension.
