Cisco FXO, can I call an idle line?

Question

Asterisk

Hello friends!
There is Asterisk and Cisco 3725 as a peer for it. There is a board with 4 FXS and 4 FXO. How can I set up a cisco so that when I receive a call from an asterisk like SIP/cisco/79998887766, it automatically selects a free FXO and calls from it.
