According to http://wiki.freeswitch.org/wiki/Mod_spandsp

/If you want mod_spandsp to send the re-INVITE for T.38 (per the standard) use this: /

/    <extension name="fax_receive">
     <condition field="destination_number" expression="^9978$">
       <action application="answer" />
       <action application="playback" data="silence_stream://2000"/>
       <action application="set" data="fax_enable_t38_request=true"/>
       <action application="set" data="fax_enable_t38=true"/>
       <action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
       <action application="hangup"/>
     </condition>
   </extension>/



I have set :

    Hi,

    I have enabled t.38 support in sipX Freeswitch and I am using FS
    CLI to send a fax (using: originate
    sofia/cciuc.ciucccc.ro/[email protected]
    <mailto:sofia/cciuc.ciucccc.ro/[email protected]>
    &txfax(/home/ciuc/stuff/lista_de_preturi.tiff)) --> 400 is the fax
    extension defined for 200 user.
    (in alias.xml i have:

    <identity>[email protected]
    <mailto:[email protected]></identity>
    <contact>sip:[email protected]</contact>
    <relation>fax</relation>
    </item>)

    I am getting an error in FS log:

    I am attaching IVR and freeswitch logs and my fax.conf.


    Anyone has any idea about this? If there's more info that I can
    provide, I'm happy to do it.


    Regards,
    Cristi
