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

but the fax was received.

Thanks Larry for the tip.
