If you need to give asterisk operational permission to a simple user on linux system, first of all you can add it on asterisk group, then you can edit “asterisk.conf” usually on /etc/asterisk/ and give rwx permission to asterisk group like this (add if they don’t exist):
astctlpermissions => 770
astctlowner => asterisk
astctlgroup => asterisk
astctl => /var/run/asterisk/asterisk.ctl
Restart asterisk to apply changes.
Common error (wrong socket permission):
[leo@srv01 ~]$ /usr/sbin/asterisk -r
