    Hello,

    
    what are you using for rtp relay? Sending here the sip trace of such
    call (e.g., ngrep) would help to spot if the signaling is updated
    correctly for nat traversal.

    
    Cheers,

    Daniel

        hi,
        

        I was wondering if in clients in a nat environment need to
          be in the dmz or need to have ports forwarded for kamailio to
          be used to connect the clients?  I have setup kamailio with
          the nat settings but am still only getting one way audio.
           chances are it has not been setup correctly but just
          checking.
        

        If i try to connect the two clients from the same network i
          can get zrtp and 2 way communication working correctly.  if
          one of the clients is on a different network the call
          initiates and answers but zrtp and 2way audio does not work.
        

        kamailio 3.3 running on ec2
        

        ttyl,
        Dave
