[SR-Users] has_sdp()??

[Juha Heinanen]

while reading rtpproxy module readme, i found this kind of example:

    if (is_method("INVITE")) {
        if (has_sdp()) {
            if (rtpproxy_offer())
                t_on_reply("1");
        } else {
            t_on_reply("2");
        }
    }
    if (is_method("ACK") && has_sdp())
        rtpproxy_answer();

does has_sdp() function really exist?  it is not listed on wiki page:
