[asterisk-users] Problem with ReceiveFAX app from FFA

Hi all,
I am running to the following problem, when using the below dialplan to
receive fax, everything works perfect till this line
exten => receive,n,ReceiveFAX(${FAXFILE}):
and then the following line cannot be executed, it's like asterisk can't go
back to dialplan and continue, the good news is when i check what is
received in my fax folder i find that the file is a valid one (not corrupted
or empty), also when I use another way to execute fax2mail, it's working
perfect and sent right to my email (test was done with the same file
received by ReceiveFAX), so I belive the problem is just when transiting
from the line that call ReceiveFAX and the line that call fax2mail (but both
work not in order or separately), the debugging of PRI channel is below
dialplan (maybe i will need to turn on debugging in receiveFAX app as well),
please advise!

I am using asterisk 1.6.2.11, FAX For Asterisk Components:
        Applications: 1.6.2.0_1.2.1
        Digium FAX Driver: 1.6.2.0_1.2.1 (optimized for barcelona_64)

[fax-rx]
exten => receive,1,NoOp(**** FAX RECEIVE ****)
exten => receive,n,Set(GLOBAL(FAXCOUNT)=$[ ${GLOBAL(FAXCOUNT)} + 1 ])
exten => receive,n,Set(FAXCOUNT=${GLOBAL(FAXCOUNT)})
exten =>
receive,n,Set(FAXFILE=/var/spool/asterisk/fax/${STRFTIME(,,%F_%T_${CALLERID(num)})}.tif)
exten =>
receive,n,Set(FAXFILENOEXT=/var/spool/asterisk/fax/${STRFTIME(,,%F_%T_${CALLERID(num)})})
exten => receive,n,Set(GLOBAL(LASTFAXCALLERNUM)=${CALLERID(num)})
exten => receive,n,Set(GLOBAL(LASTFAXCALLERNAME)=${CALLERID(name)})
exten => receive,n,NoOp(**** SETTING FAXOPT ****)
exten => receive,n,Set(FAXOPT(ecm)=yes)
exten => receive,n,Set(FAXOPT(headerinfo)=MY FAXBACK RX)
exten => receive,n,Set(FAXOPT(localstationid)=15184893772)
exten => receive,n,Set(FAXOPT(maxrate)=14400)
exten => receive,n,Set(FAXOPT(minrate)=2400)
exten => receive,n,NoOp(FAXOPT(ecm) : ${FAXOPT(ecm)})
exten => receive,n,NoOp(FAXOPT(headerinfo) : ${FAXOPT(headerinfo)})
exten => receive,n,NoOp(FAXOPT(localstationid) : ${FAXOPT(localstationid)})
exten => receive,n,NoOp(FAXOPT(maxrate) : ${FAXOPT(maxrate)})
exten => receive,n,NoOp(FAXOPT(minrate) : ${FAXOPT(minrate)})
exten => receive,n,NoOp(**** RECEIVING FAX : ${FAXFILE} ****)
exten => receive,n,ReceiveFAX(${FAXFILE})
exten => receive,n,System('/usr/local/bin/fax2mail -p -f "${FAXFILENOEXT}"
--cid-number ${CALLERID(num)} --cid-name "${CALLERID(name)}" --dest-name
"Sir/Madam"')
