Switch from Playback to SendFax

I have the Asterisk wich connected using SIP peer to CiscoAS5350 2E1 ISDN PRI. Asterisk run script to make call-file for notification users with wav file (Dial and then Playback extensions). But somethimes Asterisk call to fax-machine in auto mode.

Can the Asterisk send fax somthing like pattern.tiff instead Playback wav file after Dial and fax tone received?
