Subject: Help on SER with Mediaproxy
To: SER HELP <serusers(a)lists.iptel.org>
Hi All
I have a scenario in which I want to deploy SER with mediaproxy & allow
everyone/anyone connecting with my SER to talk to each other. I am using
ONSIP gettingStarted document. In order to allow everyone to connect to my
SER without authentication I commented the following portion in ser.cfg:
in Route[2]
#if (!www_authorize("","subscriber")) {
# www_challenge("","0");
# break;
#};
#if (!check_to()) {
# sl_send_reply("401", "Unauthorized");
# break;
#};
# consume_credentials();
and in Route[3]
# if (!proxy_authorize("","subscriber")) {
# proxy_challenge("","0");
# break;
#} else if (!check_from()) {
# sl_send_reply("403", "Use From=ID");
# break;
#};
#consume_credentials();
Now when I try to connect 2 UA (Simpleopal) from behind a same NAT, they do
get registered, & records also appear in location table of DataBase. But
when I place call from UA1 to UA2 like "call sip:UA2@aa.bb.cc.dd", where
aa.bb.cc.dd is the public IP of my SER machine (mediaproxy is also running
on same machine), it ends up showing transport error. On SER side:
A) SER logs say:
on lookup() "UA2 not found in usrloc" and on is_local() "Realm
'ab.cc.dd.ee'
is not local". the is_lcoal appears again saying "Realm 192.168.0.241 is not
local" where 192.168.0.241 is UA2's local IP.
B)Mediaproxy log says:
command request c78d68c6-fbf4-1810-80b4-0050badb4a03@UA1 203.82.51.9:5000:audio

session c78d68c6-fbf4-1810-80b4-0050badb4a03@UA1: ended (did timeout).
(203.82.51.9) is my LAN's public IP aa.bb.cc.dd is the public IP of SER
machine
C) using ngrep I found out that it sends an "SIP/2.0 408 Request Timeout"
cant figure out whats going on, anybody having any idea please help.
Thanx in advance
