Dear Klaus,
Since I have Usrloc record made for registration of myUA behind nat looks
like:
Contact: <sip:1234@192.168.10.50:2305
;transport=TCP;line=7e1d8b95f65b25a>;expires=600;received="sip:27.96.63.122:49202
;transport=TCP"
I thought my rtpproxy is running.
However , the call can be established even without NAT enable, and it also
ends unusually after 36s.
Attachment is the ngrep log in my Kamailio server side on 5060 port.
( I have replaced my server ip as xx.xx.xx.xx and the UA name as myUA)
Any hint will be great appreciated.

This sounds like a NAT problem, where the callee does
not receive the
ACK request (INVITE-200OK-ACK).

Hi List,
I have a Kamailio3.1 server and RTPProxy running in WAN.
The calls between UA will automatically terminated in Callee UA side 36s
after connected, while no one sends a BYE.
While Kamailio and UA are in LAN at all , everything is just working
well.
Is it my rtpproxy doesn't working correctly or something else is wrong?
What can I do to fix it.
Any hint??
BTW,
Kamailio is installed following official guide
http://www.kamailio.org/dokuwiki/doku.php/install:kamailio-3.1.x-from-git
The kamailio.cfg wasn't changed at all except
for below:
-----------------------------------------------------------------------------------------
1) adding the following lines:
#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_NAT
2)uncommenting the line below in route[REGISTRAR],
setbflag(FLB_NATSIPPING);
3)change rtpproxy port corresponding
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:22222
<http://127.0.0.1:22222>")
-----------------------------------------------------------------------------------------
and my rtpproxy1.2.1 was installed by apt-get install rtpproxy,
with
1) /etc/default/rtpproxy changed into:
# Defaults for rtpproxy
# The control socket.
#CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock"
# To listen on an UDP socket, uncomment this line:
CONTROL_SOCK=udp:127.0.0.1:22222 <http://127.0.0.1:22222>
LISTEN_ADDR=xx.xx.xx.xx
# Additional options that are passed to the daemon.
EXTRA_OPTS="-l ${LISTEN_ADDR}"
2) and started by
rtpproxy -l xx.xx.xx.xx -s udp:localhost:22222 -u kamailio
Your help will be great appreciated.
Coca
