Thank you for reply.

Of course I have fax detect mechanism in dialplan. This option is for 
old fax machines were some one calls from fax and asks for fax tone. So 
called person would press *7 and rxfax will send a fax tone to the 
caller's fax machine to initiate fax transmitting.

This is spandsp.conf without comments:
