    HI Rodrigo, <br>
    <br>
    You can do this with dialog module using set_profile_size and
    get_profile_size<br>
    <br>
    get_profile_size("SomeProfile","Calls_From_CX","$var(size)");<br>
    if ( $(var(size){s.int}) &gt;= 1) ) {<br>
                            send_reply("486","Busy Here");<br>
                            exit;<br>
                    }<br>
    <br>
    Regards<br>

        <p>Hi.</p>
        <p><br>
        </p>
        <p>In a test case with OpenSIPS, I have:</p>
        <p><br>
        </p>
        <p>C1 = caller 1.</p>
        <p>C2 = caller 2.</p>
        <p>D1 = callee 1.</p>
        <p>D2 = callee 2.</p>
        <p><br>
        </p>
        <p>C1, C2, D1, D2 are all SIP UAs and they are registered in my
          OpenSIPS.<br>
        </p>
        <p><br>
        </p>
        <p>C1 wants to call D1.</p>
        <p>C2 wants to call D2.</p>
        <p><br>
        </p>
        <p>According to special requirements in my current project, C2
          must receive SIP  'busy here' from OpenSIPS, whenever C1 is
          already talking to D1 or when D1 has already received SIP
          INVITE from C1 but not answered it yet.</p>
        <p><br>
        </p>
        <p>Is it possible, by means of OpenSIPS configuration file,
          create an solution to return 'busy here' to C2, for such test
          case?</p>
        <p><br>
        </p>
        <p>How could be a kind of example of code for that?</p>
        <p><br>
        </p>
        <p>Any hint will be very helpful!</p>
        <p><br>
        </p>
        <p>Best regards.<br>
        </p>
