Canon PIXMA MX360 Function Manual page 7

Available options when the answering machine is not
connected to the MX360.
You can use the MX360 in the default mode ("Tel Priority" Mode) and receive
faxes while you are home. The only way the MX360 can receive faxes when
you are not home is to have the answering machine connected to the MX360.
Another option is to obtain a "Distinctive Ring" service from your phone provider
and set the MX360 to "DRPD Mode". This option will allow you to receive faxes
when you are not home.
