I searched extensively on this and did not find anything conclusive except
the general understanding that on TDM cards every instalation is different
whereas for BRI /PRI it should work.
As for the config, Asterisk just works perfectly well with voice
conversations over the FXO line. I add one IAX extension in * for the
IAXModem and then in the IAXmodem configure the default modem as the one
that is registered in *. If I make a Fax call to my mobile, it rings and I
can hear the Fax on the other side. So, the problem I believe is in the
negotiation/sinchronization where something is broken at some point.
I would like to know wether it is possible to solve this adjusting some
parameter in some config file or I should just forget it and use a digital
line instead.
Thanks,
Jose L.

I have had great results via PRI -> Asterisk -> IAXModem -> Hylafax
Post your log results and configs.
