Space estimation

spooldir size - space for packets records

with default compression settings of voipmonitor you can count aprox 1MB/1minute of 2RTP streams (1 leg with g711 codec), if you have 2legs per call you can count aprox 2MB/1minute of record (SIP+RTP+flow charts)

CDR space for mysql's datadir

For database you can count very aprox. 2KB per CDR record with default table compression enabled (default mysqlcompress = yes in /etc/voipmonitor.conf)
