Some additional information which may help you with your installation.
I have 4 IAX Modems named iaxmodem0 - iaxmodem3. I use iaxmodem3 for
outbound fax transmissions.
I created a queue for the other 3 modems, here is my entry in queues.conf:
[hylafax-iax]
strategy=linear
ringinuse=yes
autopause=no
retry=4
timeout=5
timeoutpriority=conf
reportholdtime=no
joinempty=strict
leavewhenempty=strict
musicclass=silence
member => IAX2/iaxmodem2
member => IAX2/iaxmodem1
member => IAX2/iaxmodem0
In case you are wondering about the 'musicclass' I have used, here is
the section from musiconhold.conf, the actual location of the files may
be elsewhere on your system:
[silence]
mode=files
directory=/usr/local/share/asterisk/silence
; ls /usr/local/share/asterisk/silence
; 10.gsm
;
; The file 10.gsm came from /usr/local/share/asterisk/sounds/en/silence
I changed 'callbackextension' in my sip.conf for the trunk so that it
would go directly to the 'fax' extension in the dialplan i.e.
'callbackextension=fax'.
I've included the console output when an incoming fax is received:

I'm sure you've already checked and confirmed you have 'alaw'
and 'ulaw'
codecs permitted in your IAX Modems, iax.conf and sip.conf configurations
To test your configuration you could set it up your environment so that
you send an outgoing fax to yourself i.e. your dial your number at the
VoIP provider, this assumes when you dial your VoIP number a connection
is made back to you, you can then troubleshoot the communication.
This is how I performed the majority of my tests.
Not sure why you haven't explored the option of terminating a fax call
in Asterisk, you will need some scripts to convert the received image to
a PDF which is then e-mailed. An offer was made to you to provide
scripts, if you set this up when your iaxmodem's aren't working a
fallback will be for Asterisk to accept the call as it falls through,
one thing you should know, if you use the T.38 Gateway in your dialplan
you will need to disabled it prior to Asterisk terminating the call. I
use extensions.ael so here is an example, I've included the macro I use
to receive a fax in Asterisk:
context from-itsp {
s => {
NoOp(Call Received ${STRFTIME(,,%F %T %z)});
Set(CHANNEL(language)=en_AU);
Set(DIALTIMEOUT=30);
Progress();
NoOp(Call Received from ${CALLERID(name)}, Tel:
${CALLERID(num)});
.
. other conditions checked and extensions dialled
.
};
fax => {
NoOp(Fax Detected ${STRFTIME(,,%F %T %z)});
Set(FAXOPT(gateway)=yes);
Queue(hylafax-iax,dRt,,,15);
Set(FAXOPT(gateway)=no);
&fax-receive(<TSID>,<Header>,FaxMaster,lmoore);
Hangup();
};
h => {
if ( "X${FAXRXFILE}" != "X" )
{
&email_rxfax();
}
NoOp(Call/Fax Ended ${STRFTIME(,,%F %T %z)});
};
};
macro fax-receive( fax-number, header-info, sender, recipient ) {
/*
${ARG1} is Receiving Station Fax Number
${ARG2} is Fax Header Information
${ARG3} is Fax Sender E-mail Address
${ARG4} is Fax Recipient E-mail Address
*/
NoOp(**** FAX RECEIVE ****);
Set(FAXOPT(localstationid)=${LOCAL(fax-number)});
Set(FAXOPT(headerinfo)=${LOCAL(header-info)});
Set(FROMADDR=${LOCAL(sender)});
Set(TOADDR=${LOCAL(recipient)});
NoOp(**** SETTING FAXOPT ****);
NoOp(FAXOPT(ecm) : ${FAXOPT(ecm)});
NoOp(FAXOPT(headerinfo) : ${FAXOPT(headerinfo)});
NoOp(FAXOPT(localstationid) : ${FAXOPT(localstationid)});
Set(RXSTART=${EPOCH});
Set(FAXRXPATH=/var/spool/asterisk/fax/received);
Set(FAXRXFILE=fax-${CALLERID(number)}-${UNIQUEID});
NoOp(**** RECEIVING FAX : ${FAXRXFILE} ****);
ReceiveFAX(${FAXRXPATH}/${FAXRXFILE}.tif,f);
NoOp(**** Subroutine Return ****);
return;
};
Cheers,
Larry.
