Hello Craig,

As said, this is just side comment, not a try to cover the problem - IMHO you are right (in regards to maddr handling in nat_traversal) and that should be fixed.

Thanks Bogdan,

I'd seen in an older mailing list message that nat_traversal went with mediaproxy and nathelper went with rtpproxy. I'll switch back to nathelper and troubleshooting my mediaproxy nat issue.

    Hello Craig,

    Not trying to deviate from the actual bug, but for both cases
    (rtpproxy and mediaproxy) the signaling modules are completely
    different from the modules talking to the external media relays.
    So, you can use the mediaproxy relay (via the mediaproxy module)
    in combination with the nathelper module for the contact fixing.

    Hi,

    I was using nathelper with fix_nated_contact and have changed
    over to using nat_traversal and fix_contact as I am having some
    other issues with mediaproxy but found that calls are failing
    with the apparent difference being that nathelper removes maddr
    from the initial INVITE Contact whilst nat_traversal leaves it
    intact.

    This is causing opensips to route the received PRACK to the maddr
    private IP in the contact header and the call to fail.

    Is this correct operation for the nat_traversal module and is
    there another way to remove the maddr from the contact?

    This is with opensips 1.10

    Craig
