This article supports you in activating the so-called debug logging in the ECSTA middleware and providing the corresponding log files for analysis. 

Log files can only be examined if meaningful anchor points are available. Therefore always provide the following additional information

    • When did the error occur (timestamp with date and time, at least to the minute)?
    • Which internal extensions were involved?
    • Which external participants were involved?
    • Process of the workflow that led to an error

For meaningful processing, all available log files (preferably the complete packed c:\ecsta...\ directory) should always be provided.


Microsoft Windows Control Panel

Note on data volume

Since the amount of data can grow rapidly, it is also recommended to check the box Delete log files daily, unless it is mandatory to log over several days.

If the driver log is already activated and has been running for some time, please first delete the old logs in the specified log files path.

Providing the log files

Click on the button "Provide logfiles" and all necessary log files are provided on the desktop as ZIP files.

Special features of ECSTA for SIP phones

Define the number of SIP files

In ECSTA for SIP phones, you can define how many SIP files should be created during logging operations. If the maximum amount (default 5) is reached, the oldest file is overwritten after reaching the maximum size.

Define the size of SIP files

In the same way, you can set the maximum size of these files.

Adjusting the log file quantity or size makes sense when analyzing larger environments, as this allows you to cover a longer period of time.

Registry settings

Please make the following setting for an adjustment in the registry:

ECSTA for SIP phones


MaxLogFileCount: Sets the number of SIP files to be written (default 5)
