Current code allows you to set _undef_ in config file: } else if (!strcmp(name, "ident")) { if (!strcmp(value, "_undef_")) { spandsp_globals.ident = ""; } else { spandsp_globals.ident = switch_core_strdup(spandsp_globals.config_pool, value); } On Thu, Mar 26, 2015 at 9:11 AM, Peter Steinbach <lists@telefaks.de> wrote:
Just for the records:
With current Freeswitch I could eleminate the Fax header line completely by patching
/usr/src/freeswitch/src/mod/applications/mod_spandsp/mod_spandsp.c spandsp_globals.ident = "SpanDSP Fax Ident"; spandsp_globals.header = "SpanDSP Fax Header";
to spandsp_globals.ident = ""; spandsp_globals.header = "";
Then you can set fax_ident='', fax_header='' in your dialstring and get an empty header
Diff for this:
diff mod_spandsp.c mod_spandsp.c.org 518,519c518,519 < spandsp_globals.ident = ""; < spandsp_globals.header = ""; ---
spandsp_globals.ident = "SpanDSP Fax Ident"; spandsp_globals.header = "SpanDSP Fax Header";

Hi Michael.
I tried the ' ', but same thing: the parameter does not show up as parsed and the harcoded default is what is used.

Hi Steve.
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.
As far as getting the header removed, I tried doing the following:
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')
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.
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.
Thanks!

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.
What do I have to do to eliminate the header line? Do I have to make changes to freeswitch source?
Thanks!
