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?
hmm, invalid argurment ... try with this line:
LM_ERR("can't send command to a RTP proxy (%s/%d) [sock %d (%d), vcnt %d]\n", strerror(errno), errno, rtpp_socks[node->idx], node->idx, vcnt);
maybe will give some hints about which value is invalid.
Here's the log after the change:
4(14415) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP proxy (Invalid argument/22) [sock 7 (0), vcnt 18] 4(14415) ERROR: nathelper [nathelper.c:2492]: proxy udp:210.13.x.y:7722 does not respond, disable it 4(14415) ERROR: nathelper [nathelper.c:3144]: no available proxies
Can you try as well with an unix file socket:
modparam("nathelper", "rtpproxy_sock", "unix:/tmp/rtpproxy.sock")
then start rtpproxy with -s unix:/tmp/rtpproxy.sock
4(17530) INFO: nathelper [nathelper.c:2369]: rtp proxy unix:/tmp/rtpproxy.sock found, support for it re-enabled 3(17529) ERROR: nathelper [nathelper.c:2429]: can't send command to a RTP proxy 3(17529) ERROR: nathelper [nathelper.c:2492]: proxy unix:/tmp/rtpproxy.sock does not respond, disable it 3(17529) ERROR: nathelper [nathelper.c:3144]: no available proxies
Thanks,

I have no solaris (sparc) to try myself...

There's no problem for the resource(CPU, mem etc.) on the server, the load is very low.
Thanks in advance! ---------- 0(27429) DEBUG: nathelper [nhelpr_funcs.c:148]: type <application/sdp> found valid 0(27429) ERROR: nathelper [nathelper.c:3144]: no available proxies 0(27429) ERROR: nathelper [nathelper.c:2627]: no available proxies 0(27429) DEBUG: nathelper [nhelpr_funcs.c:148]: type <application/sdp> found valid 0(27429) INFO: nathelper [nathelper.c:2369]: rtp proxy udp:210.13.124.15:7722 found, support for it re-enabled 0(27429) DEBUG: nathelper [nathelper.c:3196]: proxy reply: 42040 210.13.124.14 0(27429) DEBUG: nathelper [nhelpr_funcs.c:148]: type <application/sdp> found valid 0(27429) ERROR: nathelper [nathelper.c:2457]: can't send command to a RTP proxy 0(27429) ERROR: nathelper [nathelper.c:2492]: proxy udp:210.13.124.15:7722 does not respond, disable it 0(27429) ERROR: nathelper [nathelper.c:3144]: no available proxies 0(27429) ERROR: nathelper [nathelper.c:2627]: no available proxies
