With current Freeswitch I could eleminate the Fax header line
completely by patching <br>
<br>
/usr/src/freeswitch/src/mod/applications/mod_spandsp/mod_spandsp.c<br>
spandsp_globals.ident = "SpanDSP Fax Ident";<br>
spandsp_globals.header = "SpanDSP Fax Header";<br>
<br>
to<br>
spandsp_globals.ident = "";<br>
spandsp_globals.header = "";<br>
<br>
Then you can set fax_ident='', fax_header='' in your dialstring
and get an empty header<br>
<br>

< spandsp_globals.ident = "";<br>
< spandsp_globals.header = "";<br>

<div>I checked into the legality of removing the header
line, and it turns out this is only a problem for
advertisements, which we are not doing.</div>
<div><br>
</div>
<div>As far as getting the header removed, I tried doing
the following:</div>
<div><br>
</div>
<div>originate
{ignore_early_media=true,absolute_codec_string='PCMU,PCMA',fax_enable_t38=true,fax_verbose=true,fax_use_ecm=true,fax_enable_t38_request=true,origination_caller_id_number='A
CALLER ID',origination_caller_id_name='A CALLER ID
NAME',call_timeout=120,fax_ident='a fax
ident',fax_header=}sofia/gateway/outbound/+15555555555
&txFax('/tmp/sample.tiff')<br>
</div>
<div><br>
</div>
<div>Even if I remove the default headers in
spandsp.conf.xml and fax.conf.xml I still get "SpanDSP
Fax Header". I noticed that this is hardcoded in
"src/mod/applications/mod_spandsp/mod_spandsp.c" line
527.</div>
<div><br>
</div>
<div>Am I not passing the null string properly somehow via
originate? I noticed in my logs that there are many
lines for "switch_event.c:1661 Parsing variable" for my
other parameters, but not for my fax_header parameter.</div>
<div><br>

<div>Thanks!</div>

<div dir="ltr">I'd like to completely eliminate
the header line sent at the top of each fax page
using spandsp. i've set fax-header to a null
string, but that doesn't seem to be removing it,
and it defaults back to 'Spandsp fax header'.
This seems to be the default in the source code
in 1.2.

<div>What do I have to do to eliminate the
