This is normal behaviour for Freeswitch as it is a b2b. A phone will also interpret the sdp as being put on-hold. Like I said, normally, they should be sending a reinvite with a non-0.0.0.0-sdp-ip so that the phone/freeswitch knows where to send the rtp to.<br>
<br>You can also use another option for hold_music in freeswitch. I think it is hold_music=hold (I&#39;m using this) where it will not send music on hold, but will pass the holdsignalling to the phone. However, this won&#39;t  change your case normally, as there should still be a reinvite with ip afterwards as far as I can tell (didn&#39;t look at trace yet).<br>

      I can see where is a problem. After 2-trasfer is made other side
      sends in sdp 0.0.0.0. which is ok, but when call is picked up we
      get only invite, without SDP, so I guess FS sends media to
      0.0.0.0.<br>
      <br>
      Is this normal behaviour for musing on hold? this proved is saying
      that thay have problems only with as.<br>
      <br>
      p.s.: they are using netcentrex-pbx.<br>

        I was just replaying to your email as I saw you email:) So, yes
        unhold-reinvite is a problem.<br>

      <blockquote type="cite">After rereading the issue, it seems similar to the
        freeswitch-&quot;issue&quot;, but I would say it is a bug in the
        netcentrex-pbx. I suppose netcentrex stays in the signalling
        path (like a b2b) in this case as they&#39;re sending a reinvite. <br>
        Without a siptrace, I would say that they should also sent the
