    My mistake, you're right, I must have picked the wrong frame. I had
    this request/reply sample and was wondering what was going... Sorry
    to have bothered you, and thank you for just pointing that out.<br>
    <br>
    By the way, is it normal that I had to change the code to have
    Kamailio accept OPTIONS messages, or did I miss a config somewhere ?<br>

      Hello,<br>
      <br>
      are you sure you got the sip reply for the request?<br>
      <br>
      Apart of cseq number, all the other tokens are different,
      including the via branch. Kamailio doesn't generate any callid or
      from-tag when using sl_send_reply() or options_reply(), it reuses
      the ones from request.<br>
      <br>
      if you still think it is the case of an issues, try:<br>
      <br>
      - add xlog() before sending the reply printing the call-id,
      from-tag via header and cseq header<br>
      - grab the pcap capture of such case<br>
      <br>
      Send the syslog messages and the pcap file here on mailing list so
      we can analyze.<br>
      <br>

        I am trying to get Kamailio working with a third party SIP
        provider. This provider pings Kamailio with OPTIONS messages,
        but Kamailio does not answer correctly: the Call-ID and the tags
        change where they should not. Here is an example:<br>

        You can see that the Call-ID change from
        "a012e080-5c41a5ce-8e5-38512c6" to
        "2defcb00-5c41aa17-93f-38512c6". Likewise, the From tag change
        ("1669836943" to "298911055"). What could be the reason for this
        ?<br>
        Moreover I think Kamailio should add the field Allow (with
        INVITE,ACK,BYE,CANCEL,INFO,OPTIONS,REFER,SUBSCRIBE,NOTIFY), but
        it does not.<br>
        <br>
        I should mention that I had to modify <i>kamailio.cfg</i> to
        have Kamailio answer to OPTIONS messages (I added <b>the code
          in bold</b>):<br>
        <br>
        if (<b>!is_method("OPTIONS") && </b>!mf_process_maxfwd_header("10"))


        {<br>
                sl_send_reply("483","Too Many Hops");<br>
                exit;<br>
        }<br>
        <br>
        if(is_method("OPTIONS") && uri==myself &&
        $rU==$null) {<br>
                <b>#</b> sl_send_reply("200","Keepalive");<br>
                <b>options_reply();</b><br>
                exit;<br>
        }<br>
        <br>
        Maybe this hack replaces an expected behavior that I failed to
        see/configure ?<br>
        <br>
        Thanks,<br>
        Jean-Marie.<br>
