I got it working. It required me to enable the track_cseq_updates in 
dialog module and use uac_auth(). Actually my config is the following:

     if (ds_is_from_list()) {
         xlog("L_INFO","[$fU@$si:$sp]{$rm} {$ru} Call from Media-Server 
         rtpengine_manage("direction=internal direction=external 
replace-origin replace-session-connection trust-address");
         uac_replace_from("", "sip:NUMBER at HOST");

failure_route[TRUNKAUTH] {
     if (t_is_canceled()) {
     if(t_check_status("401|407")) {
         xlog("L_INFO", "Got 401/407 sending uac_auth() and t_relay()");
         $avp(auser) = "USERNAME";
         $avp(apass) = "SECRET";
         $avp(arealm) = "REALM";

Now I've just last question on this topic: what's the best way to 
replace credentials (USERNAME, SECRET, REALM) from db?
I've to manage also the uac_replace_from.
What I want is to avoid to change the configuration everytime a new 
trunk is added.

Best Regards,
