      after the call is answered (second trasfer) they send first invite
      withoud SDP, we send back 200 ok SDP and than they sends ACK SDP
      in which they send right ip.<br>
      <br>
      According to RFC this is ok. Is this maybe bug on FS side?<br>

        so after other side puts you on hold our side gets reinvite with

        from trasfer there should be another reinvite with ip in sdp for

        Do you maybe know if this is also defined in RFC as I unable to

        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'm using this) where it will not
        send music on hold, but will pass the holdsignalling to the
        phone. However, this won't&nbsp; change your case normally, as there
        should still be a reinvite with ip afterwards as far as I can
        tell (didn't look at trace yet).<br>

                other side sends in sdp 0.0.0.0. which is ok, but when

                Is this normal behaviour for musing on hold? this proved
