Hi all.
I've got nathelper and rtpproxy working very well with my firewall. However I do still recieve these messages in my syslog. I am only catching 183 and 2xx errors in my onreply_route so I'm very confused how to prevent these errors.
I'm using ser-0.8.99-dev12. Can anyone give me some advise? Cheers, Paul

Hi All.
I've hacked my ser.cfg but can someone comment on why I would be recieving a "200 OK" with a Content-Length: 0?
The change I made to my onreply_route is below. The only thing I can see about these messages versus others is that the CSeq says "CSeq: {some digits} BYE" with "Content-Length: 0".
So for these messages I'm just not calling force_rtp_proxy().
I don't know if this is a symptom of my Grandstream BT100 only of if other ATAs or IP phones do this.
Regards, Paul
onreply_route[1] {
if (isflagset(2) && status =~ "(183)|2[0-9][0-9]") {
fix_nated_contact();
if (!(search("^Content-Length:\ 0")) { force_rtp_proxy(); };
} else if (nat_uac_test("1")) {
fix_nated_contact(); }; }

You answered your question!
Not every 200 OK mandated to have content. Only 200 OK received in reply to INVITE will have content. Also, 180 or 183 may have early media description.
You may be doing t_on_reply for all the methods. IMO, you will need to do that only for INVITE.
Thanks for the information.
I did try to process only INVITE messages, but when I do that I end up with one-way audio. So for now I'm going to keep on processing all 183 and 2xx messages.
Thanks again. Paul
