[Asterisk-Users] Receiving faxes and then sending them on

[Frederik Fix]

Hi,
I'm trying to setup a system where incoming faxes are received using  
SpanDSP and then send on to another (remote) fax machine. The SpanDSP  
part is working excellently, however I dont seem to be able to get  
the forwarding part to work. Heres what I put into my extensions.conf:

exten => s,4,Answer()
exten => s,5,Set(FAXFILE=/tmp/fax-${UNIQUEID}.tif)
exten => s,6,Set(EMAILADDR=ingrid.fix at offix-koeln.de)
exten => s,7,Set(EMAILADDR=${ARG1})
exten => s,8,rxfax(${FAXFILE}|debug)
exten => s,9,system(/usr/local/sbin/mailfax ${FAXFILE} ${EMAILADDR} $ 
{CALLERIDNUM})
exten => s,10,Dial(${ARG2})
exten => s,11,txfax(${FAXFILE}|caller)
exten => s,12,Hangup

Asterisk does start dialing at priority 10 however as soon as the  
remote fax hangs up that call gets destroyed as well.

Is there anyway to do something like this?

Kind regards,
Frederik Fix
