Decide the first fxo port to use

Hi all,
i’m using a digium card with 4 fxo ports on Asterisk.
When i make a call Asterisk uses the 4th port, if it is busy the 3rd, else the 2nd, else the 1st.
I’d like to know if there is a way to force Asterisk to use the fxo ports from the 1st to the 4th… it is just a curiosity.

I add the part of the zapata.conf file that could be useful:
channel => 1-4

In your dial plan change the G to g


Exten => _X.,1,Dial(ZAP/g0/${EXTEN})
