permissions module introduces a permissions checking system based on different fields a SIP message. The way the rules are defined is similar with the one used by tcpd, where rules are kept in plaintext files (hosts.allow, hosts.deny).

It provides OpenSER with support for checking on: permission to place a call, permission to register, permission for referral to a certain destination and permission to trust a request without authentication.
