    <tt>Hello </tt>Kchitiz,<br>
    <br>
    If only called party or both are sending media is up the end-devices
    implementation - from SIP and SDP point of view there is no
    difference - both end points have the SDP of the other party, so
    both of them are able to send and receive RTP (if they want). But be
    careful of the sendonly&nbsp; / recvonly indications in SDP.<br>
    <br>
    From OpenSIPS + Media relay point of view there is no difference, it
    should work with a default NAT traversal script.<br>
