    Hi Flavio,<br>
    <br>
    It seems the 487 that is received does not have a To Tag, and thus
    that error.<br>
    Aside from the error in the log file, is there any other
    miss-behaviour, like the dialog hanging, etc ?<br>
    <br>
    Regards,<br>

              &gt;<br>
              &gt; Thanks for your reply, I'm using 1.7.2, The
              validate_dialog was commented, I<br>
              &gt; will enable it later and check the results.<br>

              &gt;&gt; Hey Flavio!<br>
              &gt;&gt;<br>
              &gt;&gt; &nbsp;Hope all is well in Brazil. Is this the latest
              1.8.x branch? Also,<br>
              &gt;&gt; are you using validate_dialog() and
              fix_route_dialog() &nbsp;in your loose<br>
              &gt;&gt; route ? I remember something similar with CANCELs
              of early dialogs<br>
              &gt;&gt; happening to us. The issue I am mentioning was
              patched sometime ago...<br>
              &gt;&gt;<br>
