<p><font size=2 face="Times New Roman"><span style='font-size:10.0pt'>Hi all,<br>
<br>
I wish you first a happy new year !!<br>
One again, I ask you some help. Thanks a lot for your patience and your answers
that really helped me.<br>
<br>
So, I want to put a SER in front of one Asterisk for the moment (more after).<br>
All Servers have public IP address and so, I don't care about the RTP/SDP
messages.<br>
All phones are behind NAT somewhere in Switerland :)<br>
<br>
<br>
I have the configuration below in openser:<br>
<br>
<br>
modparam("dispatcher", "list_file",
"/etc/openser/dispatcher.list")<br>
#modparam("dispatcher", "force_dst", 1)<br>
modparam("dispatcher", "flags", 2)<br>
<br>
modparam("usrloc", "db_mode", 0)<br>
#modparam("rr", "enable_full_lr", 1)<br>
<br>
route{<br>
<br>
<br>
xlog("L_ALERT",
"[$rm] from [$fu] to [$tu]\n");<br>
<br>
if
(!mf_process_maxfwd_header("10")) {<br>
sl_send_reply("483","Too Many Hops");<br>
exit;<br>
};<br>
<br>
if (msg:len >= 2048 ) {<br>
sl_send_reply("513", "Message too big");<br>
exit;<br>
};<br>
<br>
# if (search("User-Agent:.*Thomson.*"))
{<br>
# };<br>
<br>
<br>
if ((src_ip==212.xxx.xxx.152) ||
(src_ip==212.xxx.xxx.153)) {<br>
if(method=="OPTIONS") {<br>
};<br>
avp_pushto("$ru","$tu");<br>
forward();<br>
<br>
}else {<br>
fix_nated_contact();<br>
force_rport();<br>
if(method=="REGISTER"){<br>
ds_select_dst("4", "0");<br>
t_relay();<br>
}<br>
else {<br>
ds_select_dst("0", "4");<br>
forward();<br>
}<br>
}<br>
}<br>
<br>
<br>
And in my dispatcher.list I have:<br>
<br>
0 sip:212.xxx.xxx.153:5060<br>
4 sip:212.xxx.xxx.153:5060<br>
<br>
<br>
<br>
With this configuration, a snom phone, a X-lite phone and a Cisco phone seams
to work ....<br>
But with the Thomson ST2030, it doesn't work.<br>
In fact, the Thomson REGISTER on asterisk, the Asterisk send a OPTION message
to the FW IP adress and the right port where the thomson is and then, after a
while, the FW close the connection. The thomson phone is so
"UNREACHABLE" on asterisk status and nobody can call it.<br>
I'm not sure that my configuration is ok in ser but I think that is a problem
with the Thomson2030. Do you had the same kind of problem or do you understand
the problem here ?<br>
<br>
<br>
Thanks for your help,<br>
