my faxrecieve macro:

[ Context 'macro-faxreceive' created by 'pbx_config' ]
  's' =>            1. rxfax(/root/testfax/testfax.tif)           [pbx_config]

asterisk says:

    -- Executing Macro("Zap/30-1", "faxreceive") in new stack
    -- Executing RxFAX("Zap/30-1", "/root/testfax/testfax.tif") in new stack
    -- Accepting call from '' to '224818020' on channel 0/30, span 1
    -- Channel 0/30, span 1 got hangup
    -- Hungup 'Zap/30-1'
