[Asterisk-Users] rxfax application

[gturner at ipcomputers.com]

attempting to get asterisk pbx to receive inbound faxes 

have defined the necessary extension as per technote; 

default]
 ; Answer the line and listen
 exten => s,1,Answer
 ; Dial an extension, let asterisk give a ringtone
 exten => s,2,Dial(IAX2/3987,40,r)
 ; Hangup if nobody picked up within 40 seconds
 exten => s,3,Hangup

 ; Did we get a fax?
 exten => fax,1,SetVar(FAXFILE=/var/spool/asterisk-fax/${UNIQUEID}.tif)
 exten => fax,2,rxfax(${FAXFILE})


 and can see the SetVar command being executed but then the console echos; 

"pbx_extension_helper: No application 'rxfax' for extension (pstn-incoming,fax,2) 

the asterisk installation is very much the 'basic' install as per the installation guide so i would guess this does not have this 'rxfax' application 

if this is correct can anyone assist with how i get the rxfax to run ??
