I am using a Digium TDM 410P card port 1 and port 4 . In port4 I have put a pstn line but I am unable to make and receive calls from outside. I have added a ZAP trunk in which I am using channel 4 instead of g0 which now looks like ZAP4. and I have added ZAP4 to inbound call and outbound call when I call out from my free pbx it says all circuits are busy or the person you are calling is unavailable. I am totally stuck from a week on it. Help appreciated please as I am very new to free pbx. My dahdi-channels.conf looks like this:

root@localhost asterisk]# vi dahdi-channels.conf
;;; line="1 WCTDM/0/0"
signalling=fxo_ls
callerid=“Channel 1” <4001>

;;; line="4 WCTDM/0/3"
