[Freeswitch-users] T.38 faxing with Gafachi

[Beary Beary]

I'm trying to send a fax directly through CLI (no NAT present) "originate 
sofia/gateway/sip.gafachi.com/1234567890 &txfax(/tmp/file.tiff)"
I've followed directions on http://wiki.freeswitch.com/wiki/Mod_spandsp to set 
settings in my fax.conf:
<configuration name="fax.conf" description="FAX application configuration">
    <settings>
      <param name="use-ecm"value="false"/>
      <param name="verbose"value="true"/>
      <param name="disable-v17"value="false"/>
      <param name="enable-t38"        value="true"/>
      <param name="enable-t38-request" value="true"/>
      <param name="spool-dir"value="/tmp"/>
      <param name="file-prefix"value="faxrx"/>
    </settings>
</configuration>

My freeswitch server communicates with SIP-provider(Gafachi) using this profile:
<include>
  <gateway name="sip.gafachi.com">
    <param name="username" value="XXXX"/>
    <param name="password" value="XXXX"/>
    <param name="register" value="true"/>
    <param name="realm" value="67.216.35.162"/>
    <param name="proxy" value="67.216.35.162:5060"/>
  </gateway>
</include>


>From the logs I can't see that T.38 is used. SpanDSP says:

In the end "fax is successfully sent" (via T4 to my understanding), but I only 
receive it on the other efax 1/20 times. What am I missing?
