I am newby in Asterisk (and VoIP) but installed and setup simple configuration between two phones and Asterisk with SIP (magazines give help me). Can i configure Asterisk for record all calls to files on disk?
Yes, using the command MixMonitor() and with the dialplan configured well you should be able to record all calls; check voip-info.org/wiki/view/MixMonitor .
Bye.
