[asterisk-users] iaxmodem / hylafax receive problem

[Kingsley Tart]

Hi,

I'm trying to receive faxes using hylafax / iaxmodem but I just can't
get it to work. We're using Sangoma E1 cards and have calls coming in
over PSTN. I've tried turning hardware echo cancellation off but it
makes no difference. This is what I get in /var/spool/hylafax/log:

I've tried starting hylafax with -o instead of -i but that makes no
difference either. I previously had hylafax-6.0.4 and iaxmodem-1.2.0 but
was getting the same problem.

Any ideas?
