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

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.
