asterisk users - Nov 2005 - how to send fax using Spandsp

Hi,
 I've been trying to get fax going for the last few days.
I can receive fax with Spandsp 0.0.2pre19 on Asterisk 1.0.9 with rxfax, but
when I tried sending the received fax file to a fax machine, I either get
"line error" or just a blank page.
  Is anyone using Spandsp to send fax to fax machines on PSTN?
 I've run out of things to try now, and I'd really appreciate if anyone
can
share some ideas/experiences here.
  Thank you.
AK

Sorry for bringing so old topic, but what should I put in 
extensions.conf for receiving faxes? Is

exten => 1234567,1,rxfax(/home/steveu/testfax.tif)

enough or do I have to answer the call before or something else?

When I'm dialing my number handled by Asterisk, there is a fax signal 
but the fax machine doesn't start sending. What can be wrong?
