You could try to get it working but it may never be 100%. If your needs are 100% then I suggest using a standard fax and get an analog line and do it the old fashioned way. If you need Hylafax type features then buy a modem that is compatible with Hylafax and run it on a different box.

Just suggestions.
Thanks,
Steve

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.
