Hi Carsten,
i tried before putting external address but once i put external address i
will get error on my /var/log/messages
Jul 6 18:06:56 c5 /usr/local/sbin/kamailio[20025]: ERROR: rtpproxy
[rtpproxy.c:2211]: incorrect port 0 in reply from rtpproxy
Jul 6 18:06:56 c5 /usr/local/sbin/kamailio[20024]: ERROR: rtpproxy
[rtpproxy.c:2211]: incorrect port 0 in reply from rtp proxy
Jul 6 18:06:57 c5 /usr/local/sbin/kamailio[20025]: ERROR: rtpproxy
[rtpproxy.c:2211]: incorrect port 0 in reply from rtp proxy
both kamailio and rtpproxy is in one box and behind nat with one interface
ip address 192.168.1.3
in the router i already port forward 5060 udp and 10000-20000 udp to
192.168.1.3.
Please adv.
Thank you very much. :)
