Add permission for users in opensips.cfg config files
I want define a simple code security (like: *789#) in opensips,
so that when users dial this code, the username added to group tables
for long distance permission. How can i do it in opensips.cfg file? In other words how can i add permission for user to dial "long distance" in opensips.cfg file? like this in commandline: "acl grant firstname.lastname@example.org local"
