[sr-dev] Call is terminated in callee side after 36s @Kamailio 3.1 @debian sqeeze64

[Coca]

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.
