The f/F option for ReceiveFAX is not in the 1.8.x builds. It was a patch for 1.8.x but it is in the 10 builds

Well, I tried and it is working in 1.8.7 version, so command 'core show application ReceiveFAX' doesn't reflect the real application options, only shows c option which is not present in the link sended by Larry. Well ...

FYI, I got this error

-- Channel 'SIP/tootaiAUDIO-000000ee' receiving FAX '/tmp/1318111488.262.tiff' [Oct 9 00:04:53] WARNING[9039]: res_fax.c:1508 receivefax_t38_init: channel 'SIP/tootaiAUDIO-000000ee' refused to negotiate T.38 [Oct 9 00:05:05] WARNING[9039]: res_fax_spandsp.c:368 spandsp_log: WARNING T.30 ECM carrier not found -- Auto fallthrough, channel 'SIP/tootaiAUDIO-000000ee' status is 'UNKNOWN' -- Executing [h@from-TOOTAiAudio:1] NoOp("SIP/tootaiAUDIO-000000ee", "Hangup Cause: 16") in new stack -- Executing [h@from-TOOTAiAudio:2] NoOp("SIP/tootaiAUDIO-000000ee", "Dial status : ") in new stack

but the fax was received.

Thanks Larry for the tip.
