Your provider for the sip trunk has to support it.

It supports it

[Fra]

So, can you provide me with some kind of step by step for configuring such a changing ?

Hylafax has no concept of what T.38 is. You need something in between Hylafax (T.30) and your ITSP (T.38). This is most commonly a T.38 gateway of some sort, whether hardware (think Audiocodes or the like), or a software solution (ITSP->Asterisk->res_fax/app_fax T.38 GW->IAXmodem->Hylafax for example).

[James Cloos]

Try using t38modem (http://t38modem.sf.net/ and already in many distributions)
with hylafax.

You configure t38modem to talk sip or h.323 with your voip provider, and
it allocates a pty to interact with hylafax.

I installed t38modem, in fact if I give command t38modem --help I can see help.
But now it's not clear to me how to connect the modem to hylafax and how to create another asterisk virtual extension in order to transfer fax calls to it. Now I have, for previous configuration when I had a PSTN line and I used IAXMODEM, a specific IAX2 extension for doing this task.
Can you guide me with a little step by step instructions? I don't understand from where to start. Thank you very much.

[Dean Yorke]

Check out pbx in a flash. They have a script that does this along with
avantfax. Take the script and you will be able to see the process and
know what you need to get it connected.
