    <tt>Hi Mario,<br>
      <br>
      First of all, you need to pick one b2b or dialog - you cannot use
      both in the same time for the same call.<br>
      <br>
      Secondly, please see the B2B tutorial
      (<a class="moz-txt-link-freetext" href="https://www.opensips.org/Documentation/Tutorials-B2BUA">https://www.opensips.org/Documentation/Tutorials-B2BUA</a>) - once
      you started the B2B session (by the b2b_init script function), the
      control over the call is passed to the b2b module, so no script
      returning.<br>
      <br>
      The b2b module will take care of your call from that point
      further, there is nothing for you to do.<br>
      <br>
      Best Regard,<br>
    </tt>
