[OpenSIPS-Users] how to make rtpproxy_stream2uac to work?

Greetings:

I am trying to play an announcement to my Caller/Alice before Callee/Bob gets the B-leg Invite. Can rtpproxy_stream2uac do what I need to do according to " invoking the
	    rtpproxy_stream2uac in the request processing
	    block on ACK transaction will play the prompt to the UA that has
	    generated original INVITE and ACK...." ? I am not sure I really understood the purpose of playing announcements to "Alice" at ACK transaction.

According to the log I have, my rtpproxy actually tried to play the audio with codec 0 and it doesn't seem to have any problems from the log file below. However I didn't here anything and I didn't get any rtp stream out from my rtpproxy.

Can someone please tell me about how it works and give me some hints?

Thank you,

(Enclosed is the detail log)

    # account only INVITEs
    if (is_method("INVITE")) {
                create_dialog();
xlog("==== aaaaa");
rtpproxy_offer();
rtpproxy_stream2uac("/usr/local/bin/tt_frank.wav", "5");
xlog("==== bbbb");
        setflag(ACC_DO); # do accounting
    }

    if (!uri==myself) {
        append_hf("P-hint: outbound\r\n"); 
        route(relay);
    }

    # requests for my domain
    if (is_method("PUBLISH|SUBSCRIBE"))
    {
        sl_send_reply("503", "Service Unavailable");
        exit;
    }

    if (is_method("REGISTER"))
    {
        if (   0 ) setflag(TCP_PERSISTENT);
        if (!save("location"))
            sl_reply_error();

        exit;
    }

    if ($rU==NULL) {
        # request with no Username in RURI
        sl_send_reply("484","Address Incomplete");
        exit;
    }

    # do lookup with method filtering
    if (!lookup("location","m")) {
        t_newtran();
        t_reply("404", "Not Found");
        exit;
    } 

    # when routing via usrloc, log the missed calls also
    setflag(ACC_MISSED);
    route(relay);
}
