    hello;<br>
    Â Â Â  you can start rtpproxy like "rtpproxy -l 120.76.118.128 -s
    udp:127.0.0.1:7722 -F -m 10000 -M 20000 -d DBUG:LOG_DAEMON"  and
    check message log.<br>
    <br>
    After authantication ,  test only INVITE packets with
    nat_uac_client(8) , rtpproxy_manage can handle INVITE packet with
    "co" flags ( rtpproxy_manage("co") )  as specified on docs.<br>
    you can check 200 OK packet with t_on_reply packets. the same logic
    can you handle sdp packets.<br>
    <br>
    Cheers<br>

      type="cite"> Hello ycaner!
      <br>
      <br>
      I download rtpproxy-2.0-RC1.tar.gz from <a moz-do-not-send="true"
href="https://github.com/winer632/rtpproxy/releases/tag/V2.0-RC1"
        target="_top" rel="nofollow" link="external">https://github.com/winer632/rtpproxy/releases/tag/V2.0-RC1</a><br>
      and did the following command:
      <br>
      <br>
      tar -xzvf rtpproxy-2.0-RC1.tar.gz
      <br>
      cd rtpproxy-2.0-RC1
      <br>
      ./configure
      <br>
      make all
      <br>
      make install
      <br>
      <br>
      Then I start rtpproxy with this command:
      <br>
      <br>
      rtpproxy -l 120.76.118.128 -s udp:localhost:7722
      <br>
      <br>
      <br>
      Then I edit kamailio.cfg in PCSCF module like this(added this line<b>loadmodule
        "rtpproxy"</b> and <b>modparam("rtpproxy", "rtpproxy_sock",
        "udp:127.0.0.1:7722") </b> )
      <br>
      <br>
      <br>
      #!ifdef WITH_NAT
      <br>
      loadmodule "path"
      <br>
      loadmodule "rtpengine"
      <br>
      <b>loadmodule "rtpproxy"</b><br>
      loadmodule "nathelper"
      <br>
      #!endif
      <br>
      <br>
      #!ifdef WITH_NAT
      <br>
      # ----- rtpproxy-ng params -----
      <br>
      #modparam("rtpengine", "rtpengine_sock", RTPPROXY_ADDRESS)
      <br>
      #modparam("path", "use_received", 1)
      <br>
      <b>modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")</b><br>
      #!endif
      <br>
      <br>
      <br>
      Next, I register a real number(18616278715) in China unicom's IMS
      , this step was success.Then call another real number 18019398639,
      no phone ringing, but failed with "Status-Line: SIP/2.0 407 Proxy
      Authentication Required". Before I add rtpproxy, there is no 407
      error. <br>
      <br>
      <a moz-do-not-send="true"
href="http://sip-router.1086192.n5.nabble.com/file/n148198/5060_unicom_407_error.pcap"
        target="_top" rel="nofollow" link="external">5060_unicom_407_error.pcap</a><br>
      <br>
      Â Before I add rtpproxy, I can hear the callee phone ringing, and
      the SIP route is like this:
      <br>
      <br>
      <a moz-do-not-send="true"
href="http://sip-router.1086192.n5.nabble.com/file/n148198/5060_unicom.pcap"
        target="_top" rel="nofollow" link="external">5060_unicom.pcap</a><br>
      <br>
      Am I doing wrong with rtpproxy? Maybe the problem is not here?
