[Asterisk-Users] recording

[kemal asad]

Is there a way to record phone conversations. I am using Asterisk with a
IP phone and  the digium hardware to make ouside calls.we need to have
all outside calls 
One S100U USB FXS Interface (including the USB cable)
One X100P PCI FXO Interface
the system is working quite well. but we have got a new requirement can
the asterisk server record all out going call. if yes please send me
links on how to set it up.
Thanks,
Kemal
