This is not from 1.6, but rather from callweaver attached to Asterisk 1.4.
When i'll finally switch to 1.6, i intend to just move those contexts
to Asterisk dialplan.

extensions.conf:

[fax_out]
exten => _X.,1,NoOp(--- sending fax to ${EXTEN} ---)
exten => _X.,n,SipDTMFMode(inband)
exten => _X.,n,TxFAX(${TIFF},caller,debug,ecm)
exten => _X.,n,Hangup()

exten => h,1,NoOp(--- done sending fax ---)
exten => h,n,NoOp(TX: REMOTESTATIONID is ${REMOTESTATIONID})
exten => h,n,NoOp(TX: FAXPAGES is ${FAXPAGES})
exten => h,n,NoOp(TX: FAXRESOLUTION  is ${FAXRESOLUTION})
exten => h,n,NoOp(TX: FAXBITRATE is ${FAXBITRATE})
exten => h,n,NoOp(TX: PHASEESTATUS is ${PHASEESTATUS})
exten => h,n,NoOp(TX: PHASEESTRING is ${PHASEESTRING})
exten => h,n,NoOp(TX: DIALSTATUS is ${DIALSTATUS})
exten => h,n,System(${SCRIPT}/fax_out_end.php --status
${uniqueid_storage} --pages ${FAXPAGES} --resolution ${FAXRESOLUTION}
--bitrate ${FAXBITRATE} --phase

exten => failed,1,NoOp(--- failed sending fax ---)


Then, to send a fax, generate tiff file and call-file.

Snapshot of my PHP generating call-file from hylafax job:

    $channel = 'SIP/'.$job['number'].'@asterisk-t38';
    $destination =
array('context'=>'fax_out','extension'=>$job['number'],'priority'=>'1');
    $vars = array(
      'LOCALSTATIONID' => 'CallWeaver-T38-TxFax',
      'T38CALL'=>'1',
      'TIFF'=>$job['private']['tiff_file'],
    );
    $callerid = 'CallWeaver T38 TxFax';
    $waittime = 180;
    $deliver_time = NULL;
    $filename = NULL;
    $retries = array();
    $callfile_dir = T38_CALLFILE_DIR.'/';

    $result = ast_originate_callfile($channel,$destination,$vars,$callerid,$waittime,$deliver_time,$filename,$retries,$callfile_dir);

Of course you'll need ast_originate_callfile which writes data to file
and then moves to correct dir. I would publish that, but it's full of
my constants and realted to much other libs..

Basically, you dial destination number (SIP/123 at privider) and send
local side of channel to fax_out,${NUMBER},1 which does SendFax.
