Dear all,

I'm trying to play Early Media instead of Ringing WHEN an 180 Ringing OR 182 Call Queue message is received from the destination UAC. In the onreply_route[1] I added the following lines in bold:

I use kamailio 1.5 and I have NAT enabled.

onreply_route[1] {
        xdbg("incoming reply\n");
        if ((isflagset(5) || isbflagset(6)) && status=~"(180)|(183)|(2[0-9][0-9])") {
                force_rtp_proxy();
        }
        if (status=~"(180)") {
                rtpproxy_stream2uac("/usr/local/etc/rtpproxy/ast-ivr.alaw","");
        } else {
            rtpproxy_stop_stream2uac();
        }
        if (isbflagset(6)) {
                fix_nated_contact();
        }
}

When I get from a UAC an 180 Ringing does not play the media and also in the syslog I see the following ERRORs:

Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:extract_body: message body has length zero
Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:force_rtp_proxy: can't extract body from the message
Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:select_rtpp_node: script error -no valid set selected
Nov 17 14:11:29 YGOR /usr/local/sbin/kamailio[4681]: ERROR:nathelper:rtpproxy_stream: no available proxies

Thanks in advance for any help

Alex
