.FF<max> = Maximum Files on the card (default 5000)
The maximum number of files on the card has two purposes.
First of all, it makes the directory on the card more manageable by
the system and any PC. Too many files in one directory makes a slow
system. The default number of 5000 is reasonable.
Secondly, a system can be built to use the card as an endless buffer,
without the problem that the card is getting full. However, this must
be calculated carefully and depends on the size of the card, the
maximum file size (see below), the auto close function (see above)
and the amount of recorded data (number of connected phones).
After the maximum number of files has been reached, the file write-
counter is reset, and older files are overwritten automatically.
The maximum tested size of the SD card is 32 GB, and the card must
be formatted with the FAT32 file system.
.FS<max> = Maximum File Size in MB (default 100)
When a file on SD card reaches the maximum file size, the file is
closed for further writing and then sent to the Tunnel server, if that
function is enabled. The name counter is incremented at the same
time and a new file is opened.
An uncompressed VoIP call produces roughly 26 Kbytes per second.
This means a little less than 90 Mbytes per hour. The default of 100
Mbytes is therefore enough for about an hour of recording. A call
that takes longer will continue in the next file, without loss of data.
.SS<start/stop> = Tunnel Send Start/Stop Time
Sending files via the Tunnel can be scheduled into a timeframe. If
lots of data has been received by the V-Tap and therefor also lots of
data must be send to the Tunnel server, it might be useful to delay
the sending to save bandwidth on the network. Sending data is then
only done between the given start and stop times.
The entered format must be "HH:MM / HH:MM". For example:
".SS22:00/08:15" means; send between 10.00 in the evening and 8.15
in the morning.
.SI<mhz> = Card Interface Speed in MHz (default 40)
This value must be changed only when there are problems with an
SD card. The default is good for most of the cards on the market.
Valid speeds to enter: 1 till 12, 15, 17, 20, 24, 25, 30, 40 and 60.
