# Fax Machine -- Incoming Polling Calls

If no Fax destinations are configured, then incoming calls from remote fax machines are disconnected. If a Fax destination is configured, a status report including all channels is delivered.

If PINs are configured then the list of fax destination phone numbers acts as a security list. Permission to receive the status report is granted only to those fax machines whose phone number (CIG/CSI) matches the number for some configured fax destination. The status report is then delivered using all the configuration options for the matching destination.
