incoming calls. The duration is rounded down to the nearest multiple of 10 seconds, e.g. 0:15:2
is a duration of 15 minutes, 20 seconds.
If a meter pulse card has been fitted and the telecom operator has enabled this option on
exchange line then the number of meter pulses for each call will also be logged. If the call unit
cost has been programmed then the correct call cost is calculated and output instead. See Call
Unit Cost on page 40 for details.
If the CDR log is sent to a serial printer, not the PC program, then the extra status messages
sent via the serial port must be disabled using the code shown below.
The last 4 digits of recorded telephone numbers of 5 digits or more may be masked with the ‘*’
character if the numbers must be kept private, this option may be toggled on and off.
The call duration is counted from the time the line is seized for outgoing calls. In the case of
ISDN calls the call duration timer is restarted when the call is answered. In the case of analogue
calls, the call duration timer is restarted at the first meter pulse; this requires the use of a meter
pulse detection card and the service enabled by your telephone service provider.
If the log call ring start and ring end code is used and CLI information is available for an
incoming call then the call will be output to the V24 port as soon as it begins to ring. It will be
output without an extension number or account number, with the call type set as ‘R’ when it
first rings. When ringing stops, i.e. it is answered or the incoming caller hangs up the line, then
the time and ring duration is output immediately to the CDR record with an ‘S’ in the call type
column, the ringing period is shown in the call duration column. If a call was answered then it
will be logged at the call end with a ‘1’ as the call type to signify an incoming call. The following
three entries in a CDR log show a typical call:
01 17 11 14:12 0:00:0 0000 R 01 112233
Call begins ringing at 14:12
01 17 11 14:13 0:00:2 0000 S 01 112233
-
Call stops ringing after 20 seconds (either answered or incoming caller hangs up)
01 17 11 14:15 0:01:5 0000 1 01 112233 12
Extension 12 took the call and was in conversation for 1min 50sec.
Hotel / Motel Operation
In addition to an immediate log of each call made, the system has a feature called hotel call logging
which may be enabled for each extension. Each call made from an extension with hotel call logging
active will be stored internally in the telephone system and not sent directly to the serial port as with
normal extensions. A code may be entered at the master extension to output all call details for one
extension via the V24 port to a connected printer or terminal program on a PC. The PC program is
able to log calls automatically. Select the menu item ‘Configuration’ ‘Misc / PC Setup’, and select
the ‘New’ option to begin a new log file or ‘Append’ to add call records to the end of an existing file.
Call details will continue to be logged until the program is closed.
The system will store a maximum of 144 call records on the 206 system and 240 records on the
208/212 system.
When the hotel call buffer has only ten empty records left, the system will send the message
‘CDR BUFFER NEARLY FULL’ through the V24 port at the end of each call until the buffer
becomes full, when the message ‘CDR BUFFER FULL *******’ will be sent. No new calls will
be logged until some calls are cleared from the buffer by outputting an extension CDR log.
When the call records for an extension are output, the call details for that extension are
removed from the system memory and logging of new calls for the extension starts again.
If the code to output call details for an extension is entered, but no calls are stored then the
message ‘NO CDR AVAILABLE FOR (ext)’ will be output.
When disabling hotel call logging for an extension, be sure to clear any records stored for the
extension with the send CDR records command.
It is possible to disable logging of calls from normal extensions so that the CDR output of
hotel logging enabled extensions is not corrupted with extra information from other extensions.
