Description

ACL

The ACL module used by res_pjsip. This module is independent of endpoints and operates on all inbound SIP communication using res_pjsip.

There are two main ways of defining your ACL with the options provided. You can use the permit and deny options which act on IP addresses, or the contactpermit and contactdeny options which act on Contact header addresses in incoming REGISTER requests. You can combine the various options to create a mixed ACL.

Additionally, instead of defining an ACL with options, you can reference IP or Contact header ACLs from the file acl.conf by using the acl or contactacl options.
