Thanks Alex but I&#39;m not sure if I understood correctly your answer : do you mean that NATHelper only handle INVITE with a unique SDP part (application/sdp) ? If NATHelper processes my INVITE with multipart, does it modify only the SDP part ?<br>

    Nathelper does not attempt to modify parts of SDP not pertinent to<br>
    its mission.<br>

        Hi<br>
<br>
        Does NATHelper support properly multipart SDP (eg. INVITE with<br>
        application/sdp and application/resource-lists+xml)  ?<br>
<br>
        Regards,<br>
