CISCO ISDN Call Statistics


The goal of this plug-in is to make accounting on ISDN call performed by Cisco router.

The Cisco ISDN Call Statistics plug-in is used to analyze the files generated by the Cisco ISDN history call plug-in. It provides in 3 tables, detailed statistic information on the ISDN activity.

Warning: The Cisco ISDN history call plug-in is absolutely required before using this program, consult the Cisco ISDN history call plug-in documentation.

For each destination, the number of calls and their duration are summarized, the average duration per call is calculated and the maximum call length is retained. Finally the sum of all the incoming, outgoing and all calls are performed. This statistic could be done per day, or on a range of days. Filters could be applied to select for example a specific destination. Statistic file could be saved and compressed. The results are immediately displayed but could be saved in a report in html format for further reading.

Launching the program

From the Directory TAB, open the contextual menu of any host with a right click, select  Tools and Cisco ISDN Stats.

Reading ISDN log Files

The file generated by the Cisco ISDN history call plug-in contains the list of all calls recorded on a specific Cisco router. The Cisco ISDN history call creates a file for each day, the file contain an entry per call, for each it stores the calling number, the called number, the duration, etc.

Cisco ISDN statistics plug-in has to read this file for generating the statistics. Results are displayed in three tables.

The interface is composed of 3 tables:

Details of all calls: This table contains all the calls, incoming or outgoing gathered from a file or a group of files. The maximum supported by this table is  10000 calls.

Statistics per call Number peer: This table contains a first analysis of the previous table. The calls are counted by source and destination peer and summarized to provide for each peer the number of calls realized and their total duration.

Totals: This table contains the summarized time for all calls separated in Incoming and outgoing calls.

The steps for using the program are simple.

First you should know what files you want to analyze. Select the file with the file selector.

For starting the analysis you have the choice between :

If you select the file on scan range option you should specify the First date and Ending date.

The file mane header is always isdnhistory... but you can specify another one if you have renamed or saved your reports under new names.

When you made a file selection the double click starts immediately the scan of the file(s). The Scanning Status bar shows you the current line read and the number of successful matches if a filter has been set.

Filtering on keywords

You can also filter within the file on a key word. It could be a name or number. Enter the Key words (two maximumn) and operator AND/OR and select a files or files to browse. The Calls containing the keyword are displayed.

Statistics description

The Statistic per call Number Peer table shows the calls for each couple of number. If two routers are able to initiate the call between them two entries are created in the table, one for the incoming call (from the point of view of the router where the log are collected) and one for the outgoing call.

Two symbols are used in front of each table entry.

The call is an incoming call

The call is an outgoing call

Each line contains the statistics for all calls made between two distinguished routers.

Column header description

Calling Number

 The ISDN call number from where the call was initiated

Called Number

The ISDN number called

Remote Host Name

The name of the host that was called

Number of Calls

The total number of calls made between this two routers

Total Time

The total communication time in 0.001 seconds for all these calls

Total Time

The total communication time in Days,Hours,Minutes,Seconds all these calls

Longest Call Duration

The longest communication time spent by a specific call

Average Duration per call

The average communication time for all these calls

Total table description

Column header description


ISDN Outgoing Calls. Call performed from this router to a remote router.
ISDN Incoming Calls. Call received from a remote router
All ISDN Calls. Both incoming and outgoing calls

Number of Calls

Total number of Calls

Total time (ms)

Total communication time in milliseconds of all calls

Total Time

Total communication time in Days,Hours,Minutes,Seconds.The sum of the upper values.

Ordering Statistics

When the statistics are displayed it is possible to reorder the result by clicking on a column header

Exporting call list to CSV file.

The list of calls could be exported into .csv files. The name of the file shoud be isdnhistory__ if you want to be able to see it from the file selection window.

Creating a report

A report could be created from the current displayed results. To create a report select the  Create Report button.

Give a Name and select OK.

Open the report by clicking on view report.

The report displays the date of generation, the name of the router.

One table displays the list of files used for the report.

The last two tables contains the total times of the calls and the table of statistics per host peer.
