What are you trying to do and do you have a T1 or ISDN line?

Re: Asterisk 1.4 Fax

at this time is terminating a SIP trunk,
each DID will get its own fax box.
I guess at this time i'm looking to find a tutorial for installing iaxmodem and hylafax as it seems to be the answer.

Re: Asterisk 1.4 Fax

Unless your provider provides a T.38 gateway, fax over SIP is pretty much guaranteed to be unusable.  Often you can get away with it over a LAN using G711a or G711u, but any of the lower bandwidth codecs won't be able to properly handle fax calls.

Whilst I haven't used it myself, I believe IAXmodem and Hylafax are used for sending and receiving faxes from a local PSTN termination point such as T1 or ISDN.

The IAXmodem web site explains the pitfalls of faxing over the internet.  See http://iaxmodem.sourceforge.net/faq.php for more info.  Last time I heard IAXModem didn't support T.38 because the IAX2 protocol didn't support T.38 - whether that's still the case or not, I don't know.

Re: Asterisk 1.4 Fax

If by "fax box" you mean an ATA with a fax machine attached them
Asterisk 1.4 with T38 passthrough should work if the SIP provider has
T.38 capabilites.

If by "fax box" you mean a 'faxmail inbox' then no Asterisk cannot
help you terminate that from SIP. Get a Cisco gateway, make sure your
provider uses T.38 and connect that to your Asterisk via T1 or E1.

There are actually two reasons. One is that T.38 over IAX is not 
defined. The other is the current T.38 termination support in spandsp is 
only for the full FAX machine it contains. T.38 termination to the class 
1 FAX modem (T.31) interface for HylaFAX is a work in progress. When 
that is done, I hope we will have a sipmodem to replace iaxmodem, 
offering bother audio and T.38 to HylaFAX functionality.

Brian,

What about some facts ?

Hardware ?

Software versions ?

Re: Asterisk 1.4 Fax

Well that answers that question.  I see that t38modem provides an H232 modem - is this unsuitable for HylaFAX's purpose? (ignoring the fact that it requires a kernel recompile on most newer distros.)

The most recent versions of t38modem can apparently provide both a SIP 
and H.323 T.38 to class 1 FAX modem interface for HylaFAX. What it 
cannot provide is an audio FAX interface. The sipmodem code I am working 
on will integrate audio and T.38 FAX processing in a single SIP entity.
