Hi Daniel,
What does the log below means? Does it mean nathelper has issue to send the
request to RTP proxy first or nathelper doesn't receive a response after
sending a request to the rtp proxy?
0(27429) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP proxy
this error is printed when write to socket fails. Do you have any firewall
running on the system? Is the user under which kamailio runs allowed to write
to sockets?
There's no firewall on the system, and I run the kamailio as root,
root 26310 1 0 02:24:19 ? 0:00
/usr/local/kamailio-3.0.2/sbin/kamailio -f /usr/local/kamailio-3.0.2/etc/kamail
You can edit module_k/nathelper/nathelper.c and replace the line 2457 with:
LM_ERR("can't send command to a RTP proxy (%s/%d)\n", strerror(errno), errno);
Recompile and reinstall. Hopefully will get more hints about what happens.
Here is the error message after the change:
2(26312) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP
proxy(Invalid argument/22)
2(26312) ERROR: nathelper [nathelper.c:2492]: proxy <udp:210.13.124.15:7722>
does not respond, disable it
2(26312) ERROR: nathelper [nathelper.c:3144]: no available proxies
what could be the cause?
Test env:
UA1 (Behind NAT) --------> Kamailio & RTPproxy (Public IP) --------->UA2
(Public IP)
Thanks,
Kevin
Cheers,
Daniel

There's no problem for the resource(CPU, mem etc.) on the server, the load is
very low.
Thanks in advance!
