Hi Piotr, There is no easy answer and exact figure as this depends very much on your configuration and hardware. In general recording is one of the heaviest operations we are consuming CPU for. The main aspects that affect to this are: - Recording format. More compresses format will consume more CPU - Concurrent calls. If you have compressed recording format and many calls end at the same time, then more CPU is used So, the answer is that depends heavily on your setup. I will anyhow try to check where the figures you mentioned are coming from. Br, Jukka
