asterisk users - May 2006 - FAX with PRI

Hi,

I have a digium T1 card installed on my Asterisk box. Protocol is PRI.
I am trying to setup so that the box can send and receive faxes. Being
able to receive faxes is a lot more important than being able to send.

I tried spandsp-0.0.2pre25, with proper app_rxfax.c file. But I am not
able to receive faxes. Soon after the connection is make the channel
hangs up. All I see on the Asterisk console is

  -- Executing Set("Zap/1-1", "(FAXFILE=/tmp/myfax.tif") in
new stack
  -- Executing RxFAX("Zap/1-1", "") in new stack
  == Auto fallthrough, channel 'Zap/1-1' status is 'UNKNOWN'
  -- Hungup 'Zap/1-1'

I will appreciate any help in resolving this issue.

Thanks,
--jt
