This suggests asymmetrical invocation of rtpproxy, for example in 200 OK but not corresponding INVITE. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/ On Oct 13, 2010, at 1:33 PM, Anders <vaerge(a)gmail.com> wrote: > Hi, > > I'm trying to get the RTP proxy to work with Kamailio (1.5), but right > now I am getting this error here: > > Oct 13 16:54:44 vn1031 /usr/local/sbin/kamailio[13622]: > ERROR:nathelper:force_rtp_proxy: incorrect port 0 in reply from rtp > proxy > > There is probably something wrong in my cfg - for the use of > force_rtp_proxy that part of my config is here below.

 Sorry, I didn't understand that. Is it good or bad that it is  asymmetrical? And if not, what should it be? As far as I understand  from my config, it first checks if NAT is set, and if so, it goes to  force_rtp_proxy if it's INVITE and unforce_rtp_proxy if it's a BYE.
