my problem is that I cannot run ‘sip show peers’ or any other sip commands from the CLI.   Solution:- Check your /etc/asterisk/sip.conf    file carefully. Find the missing one and restart the asterisk server (service asterisk restart) and go to asterisk cli prompt (asterisk -r) and type the SIP command. 🙂
