Ok, I think the whole point is that I don't undestand how the dialplan
works.

I started from 0 ... now on the sofia.conf.xml I have this:
<configuration name="sofia.conf" description="sofia Endpoint">

 <global_settings>
   <param name="log-level" value="0"/>
   <!-- <param name="auto-restart" value="false"/> -->
   <param name="debug-presence" value="0"/>
 </global_settings>

       <profile name="fax">

         <X-PRE-PROCESS cmd="include" data="../gateways/*.xml"/>
         </gateways>

         <domains>
           <domain name="all" alias="false" parse="false"/>
         </domains>

         <settings>

           <param name="t38-trace" value="true"/>
           <param name="dialplan" value="XML"/>

           <param name="local-network-acl" value="localnet.auto"/>

           <param name="inbound-zrtp-passthru" value="false"/>

           <param name="sip-port" value="5060"/>
           <param name="rtp-ip" value="$${sofia_ip}"/>
           <param name="sip-ip" value="$${sofia_ip}"/>
           <param name="ext-rtp-ip" value="$${sofia_ip}"/>
           <param name="ext-sip-ip" value="$${sofia_ip}"/>

           <param name="rtp-timeout-sec" value="300"/>
           <param name="rtp-hold-timeout-sec" value="1800"/>

           <param name="tls" value="false"/>
           <param name="tls-only" value="false"/>
           <param name="tls-bind-params" value="transport=tls"/>
           <param name="tls-sip-port" value="5061"/>
           <!-- Location of the agent.pem and cafile.pem ssl certificates

           <param name="tls-cert-dir" value="$${base_dir}/conf/ssl"/>
           <param name="tls-passphrase" value=""/>
           <param name="tls-verify-date" value="true"/>
           <!-- set to 'in' to only verify incoming connections, 'out' to
only verify outgoing connections, 'all' to verify all connections, also
'in_subjects', 'out_subjects' and 'all_subjects' for subject validation.

           <param name="tls-verify-policy" value="none"/>
           <param name="tls-verify-depth" value="2"/>
           <!-- If the tls-verify-policy is set to subjects_all or
subjects_in this sets which subjects are allowed, multiple subjects can be
split with a '|' pipe -->
           <param name="tls-verify-in-subjects" value=""/>
           <!-- TLS version ("sslv23" (default), "tlsv1"). NOTE: Phones may
not work with TLSv1 -->
           <param name="tls-version" value="tlsv1"/>
         </settings>
       </profile>
 </profiles>

</configuration>


Then on the t38_transconde.xml file I have this.

<include>
<context name="incoming">
<extension name="t38_transcode">
 <condition field="destination_number"
expresion="^(\+1|1)?([2-9]\d\d[2-9]\d{6})$">
   <action application="set" data="fax_enable_t38=true"/>
   <action application="set" data="sip_execute_on_image=t38_gateway peer
nocng"/>
   <action application="bridge"
data="sofia/external/$1$2@$${external_sip_proxy}"/>

 </condition>
</extension>
</context>
</include>


I could see on the /var/log/freeswitch/freeswitch.xml.fsxml file that the
t38_transcode.xml file its included ... but still get the same error on on
the console, so something terrible wrong I'm missing here ... :-(

Also ... it's possible to directly send the calls sofia/$1$2@$${external} ?
... I mean, sending the call directly to a URI, with username/password and
so on ... instead of having to define a profile for it.
