<br>
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?<br>
<font color="#ff0000">0(27429) ERROR: nathelper
[nathelper.c:2457]: can't send command to a RTP proxy<br>
</font></blockquote>
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?

You can edit module_k/nathelper/nathelper.c and replace the line
2457 with:<br>
<br>
LM_ERR("can't send command to a RTP proxy (%s/%d)\n",
strerror(errno), errno);<br>
<br>
Recompile and reinstall. Hopefully will get more hints about
what happens.<br>

Here is the error message after the change:
<br>
<font color="#0070c0">2(26312) ERROR: nathelper
[nathelper.c:2457]: can't send command to a RTP proxy<font

2(26312) ERROR: nathelper [nathelper.c:3144]: no available
proxies</font><br>
what could be the cause?<br>
</blockquote>
hmm, invalid argurment ... try with this line:<br>
<br>
LM_ERR("can't send command to a RTP proxy (%s/%d) [sock %d (%d),
vcnt %d]\n",<br>
strerror(errno), errno,
rtpp_socks[node->idx], node->idx, vcnt);<br>
<br>
maybe will give some hints about which value is invalid.<br>
<br>
Can you try as well with an unix file socket:<br>
<meta http-equiv="content-type" content="text/html; charset=GB2312">
<br>
modparam("nathelper", "rtpproxy_sock", "unix:/tmp/rtpproxy.sock")<br>
<br>
then start rtpproxy with -s unix:/tmp/rtpproxy.sock<br>
<br>
I have no solaris (sparc) to try myself...<br>
<br>
Cheers,<br>
Daniel<br>
