Rejecting Anonymous Calls

The device can reject anonymous calls received from the IP and destined to an FXS port. To configure the functionality, use the ini file parameter, RejectAnonymousCallPerPort. If configured for a specific port and the port receives an anonymous call, the device rejects the call and responds with a SIP 433 (Anonymity Disallowed) response. For a description of the parameter see Caller ID Parameters.
