Individual calls

Individual calls tab shows the list of incoming and outgoing individual (direct) calls for a user, including the missed ones. Emergency calls are highlighted in red.

If the server is configured for recording media, you can replay the call (audio or video) or save it to the local drive and replay with the media player of your choice. Otherwise, only call statistics (date, participants, direction, duration, and so on) are displayed.

To sort the calls by a certain column or change the sort order, click the column header. The current sort order is shown as a small arrow near the column name. By default, the calls are sorted by date, newest first.

You can also rearrange the list by dragging the columns.


  1. Select the call from the list. If it contains audio or video recording, the built-in player becomes active.
  2. Click Play button to replay the call. Alternatively, simply double-click the call.
  3. Click Pause button to temporary pause the replay.
  4. Click Stop button to cancel the replay. The player automatically stops when you click another call with recording.

Gray bars above the player timeline show the intervals when audio is available.


If the call was encrypted, you will be requested a decryption key. If there were several encrypted parts during the call, you will be prompted for a decryption key every time the encrypted part is played.


  1. Select the call from the list. If it contains audio or video recording, Download button becomes active in the player.
  2. Click Download button.

Audio calls

Audio calls can only be saved as Waveform Audio (WAV) files.

  1. Provide a file name.
  2. Click Save button.

Video calls

Video calls can be saved in a proprietary Tassta Export Format (TEF) or in MPEG-4 format (MP4).

Tassta Export Format (TEF) is the original format of storing video recordings on TASSTA servers. As such, the recordings are saved much faster and do not require resource-consuming conversion. However, TEF files can only be played in T.Recorder.

  1. Provide a file name.
  2. Click Save button.

MPEG-4 (MP4) files can be played with any modern player on almost any device. Saving recordings as MP4 requires conversion:

  1. Provide a file name.
  2. Specify the video resolution.
    The resolution might be smaller or larger than the original recording. If the resolutions do not match, the video is resampled.
  3. Click OK button and wait until the recording is converted and saved to a file. It might take a while, depending on the length of the call and the performance of the machine where T.Recorder is installed.
    You can cancel the conversion at any moment. In this case, the file is not saved.

Exporting calls history

Individual calls history can be exported to a comma-separated values (CSV) file. The export only includes call statistics, without audio/video data.

  1. Click Download on top of the list
  2. Provide a file name.
  3. Click Save button.
