    <tt>Hi Surya,<br>
      <br>
      Usually it is an matter of an option in the client - it should be
      automatically set (the TCP option) if the UAC wants to be reached
      back via TCP.<br>

                Hi,<br>
                <br>
                <br>
                I am testing opensips presence server 1.8.3 using sipp.
                I am using TCP as<br>
                the transport. When I send SUBSCRIBE, 200 OK is received
                fine but the NOTIFY<br>
                is sent on UDP.<br>
                <br>
                When testing from 2 SIP clients it works fine on TCP. Is
                there something<br>
                special to take care while testing TCP from SIPP?<br>
                <br>
                Below is the command and scenario file.<br>
                *./sipp 192.168.192.131 -t t1 -sf sn.xml -m 1 -i
                192.168.192.128*<br>
                -------------------------------------------------<br>
                &lt;?xml version="1.0" encoding="ISO-8859-1" ?&gt;<br>
                &lt;scenario name="subscribe"&gt;<br>
                   &lt;send start_rtd="1"&gt;<br>
                        &lt;/send&gt;<br>
                <br>
                   &lt;recv response="200"&gt;<br>
                   &lt;/recv&gt;<br>
                <br>
                   &lt;recv request="NOTIFY" rtd="1"&gt;<br>
                   &lt;/recv&gt;<br>
                <br>
                    &lt;send crlf="true"&gt;<br>
                        &lt;/send&gt;<br>
                <br>
                &lt;/scenario&gt;<br>
                -------------------------------------------------<br>
                <br>
                I am not able to figure out what the problem is. I
                suspect it is something<br>
                to do with sipp but not sure.<br>
                I couldn't find anything on internet, hence, posting
                here.<br>
                <br>
                Thanks,<br>
