Done but now I have

[Oct  8 19:20:20] WARNING[8771]: res_fax.c:1508 receivefax_t38_init:

How can I allow Audio FAX?

I saw a discussion on asterisk-devel from january 2010 about new spandsp 
where Kevin P. Fleming told you to do an "core show application 
ReceiveFAX" to find out how to enable this feature. I'm perhaps a little 
bit stupid but can't find any usable information while using this 
command :-(

Thanks for your help
