Try to check for the asterisk process instance by following command.
ps -eaf | grep asterisk. It will give you the process active status. After that try to excute your command asterisk -c . If you are still getting errors in starting the asterisk process please post your installation steps .

Your asterisk cli is saying it’s configured correctly. It is showing one point.i.e the zaptel drivers not configured in your asterisk box.
