We had a need, for a most inexpensive, yet reliable way to capture the call detail records for our CS1000.   There are a dozen or so commercial packages available for this, offering varying features.

…as a work around, we took a Ubuntu box that was in close proximity, and used an outstanding utility called ttylog to dump the serial output to a txt file.  Quite simple….

then to make the text file available…  we placed a few lines in the crontab file to stop the utility, move the files, and restart the process..    worked flawlessly for about a year now.
