Permissions: module is used to determinate if a call has appropriate permission to be established. Permissions can be managed in configuraton files simular to hosts.allow and hosts.deny:

The search stops at the first match:

• Routing will be allowed when a (FROM, Request URI) pair matches an entry in the /usr/local/etc/ser/permissions.allow file.
• Otherwise, routing will be denied when a (FROM, Request URI) pair matches an entry in the /usr/local/etc/ser/permissions.deny file.
• Otherwise, routing will be allowed.

A non-existing permission control file is treated as if it were an empty file. Thus, permission control can be turned off by providing no permission control files.

The FROM header and Request URI are always compared with regular expressions! For the syntax see the sample file: config/permissions.allow
