    Hi Brian,<br>
    <br>
    i have installed 1.4.12 on test environment (in production i have
    1.4.8) and it does not send UPDATE in the middle of the call. The
    same UAC, router, server, same opensips.<br>
    <br>
    What could be a reason that Fs will send UPDATE with sdp in the
    middle of the call? I need get this UPDATE wit sdp by FS, so that I
    will be able to fix this on opensips in production :)<br>
    <br>
    But anyway I do not know why FS sends UPDATE with sdp as in 200 ok,
    which was send at the beginning of the call are the same sdp values
    as in UPDATE.<br>

      Hi Brian,<br>
      <br>
      i think i found an issue. Please let me know if
      aggressive-nat-detection will help as a do not find any
      appropriate explenation what exactly does it do.<br>
      <br>
      Freeswitch in my case is for RTP, so opensips relays all call
      throught FS and than FS sends it back to opensips which sends a
      call to UAC.<br>
      <br>
      Problem is that Fs sends in the middle of the call UPDATE request
      (which is ok) and than UAC sends back 200 ok. In this 200 ok the
      contact address is private (also in SDP) as opensips does not
      replace contact ip with public source ip , so FS begins to send
      media to private ip which is the reason why media stops.<br>
      <br>
      I think this problem was also present with 1.2.x version but FS
      did not sends updates. Do not understand this sentence wrong as FS
      is not behaving wrong i am just explaning why I have this in new
      version :)<br>
      <br>
      Will Aggressive nat detection fix this or I should fix this on
      opensips and what exactly does aggresive nat detection do?<br>
      <br>
      tnx!<br>

              <br>
              first my FS is on public ip.<br>
              <br>
              We have migrated  from 1.2.x to Version<br>
              1.4.8+git~20140910T181155Z~9f72b11892~64bit (git 9f72b11

              18:11:55Z 64bit as we needed different server.<br>
              <br>
              I have noticed that a lot of costumers are complaining
              that a lot of<br>
              phone call has been cut in about 1:30 min of the call.
              From what I can<br>
              see from sip trace is that FS begins to send media to
              private ip.<br>
              <br>
              link to trace: <a moz-do-not-send="true"
                href="http://pastebin.com/9M6X6SFp" target="_blank">http://pastebin.com/9M6X6SFp</a><br>
              <br>
              So, rtp is send first to right ip and media is ok but in
              about 1:30 min<br>
              of the call the FS sends update and begin to send rtp to
              private ip.<br>
