I suspect I followed a guide much like the one you have used including
information found on voip-info - sorry, I can't seem to find any
bookmarks of relevant information.
I spent an enormous amount of time getting it working and working very
well, the real issue was getting T.38 working - I applied a patch to
Asterisk version 1.8 to get the T.38 gateway functionality.
I would have started off my testing by confirming communications between
two IAX modems, I presume you are using HylaFAX too.
Once the communications between the two IAX modems was working I
progressed with testing sending and receiving faxes using G711A through
my VoIP service and a modem attached to a PSTN service, suffice to say
T.38 functionality was the key to getting reliable faxes working through
VoIP at least when traversing the Internet, fortunately my VoIP provider
facilitates T.38.
Using an SPA8800 on my network I tested sending and receiving faxes with
a modem attached to the SPA8800, it worked in G711A and T.38.
I progressed to Asterisk 11 where the T.38 gateway functionality is
better along with other improvements.
What is the output on your system for:
fax show version
Cheers,
Larry.

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;
};

In your sip configuration for your 'mytrunk' peer have you set
applicable options e.g.:
t38pt_udptl=yes,redundancy,maxdatagram=400
In your extensions.conf you could and probably should set the
following option prior to dialing the IAX channel, this is to
enable the T.38 gateway feature of Asterisk 11:
Set(FAXOPT(gateway)=yes)
I have it working in my installation however I have incoming
voice calls too hence I use 'faxdetect' to direct the call to
the 'fax' extension.
Cheers,
Larry.
