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")

-----------------------------------------------------------------------------------------

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

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.
