Hi Users
Hi Users,
I install the openser 1.0.1 and rtp proxy 0.3 in same Linux System.
Openser server is located with public id xx.xxx.xxx.xx of 192.168.2.2 ,
And UAC are outside the NAT,
1) When one UAC call to other UAC( are both in outside the NAT where
openser server), after the INVITE method get request by server, after 32
second its hung up automatically, Voice is ok , and callee is hung upping, not
caller,
2) UAC ( inside the nAT , openser server ) calls to UAC (outside the NAT
) in not hung uping and voice is not ok....
3) UAC calls to UAC (both are in inside the NAT, where OpenSER is
located in same network ).
Where is the problem, in NAt with rtp or networking,
Here by My openser.cfg with routing logic...
route{
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
exit;
};
if (msg:len >= 2048 ) {
sl_send_reply("513", "Message too big");
exit;
};
# NAT detection
route(2);
if (!method=="REGISTER")
record_route();
if (loose_route()) {
append_hf("P-hint: rr-enforced\r\n");
route(1);
};
if (!uri==myself) {
append_hf("P-hint: outbound\r\n");
route(1);
};
if (uri==myself) {
if (method=="REGISTER") {
if (!www_authorize("xx.xxx.xxx.xxx", "subscriber")) {
www_challenge("xx.xxx.xxx.xxx", "0");
exit;
};
if (isflagset(5)) {
setflag(6);
# if you want OPTIONS natpings uncomment next
# setflag(7);
};
save("location");
exit;
};
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
exit;
};
append_hf("P-hint: usrloc applied\r\n");
};
route(1);
}
route[1] {
if (subst_uri('/(sip:.*);nat=yes/\1/')){
setflag(6);
};
if (isflagset(5)||isflagset(6)) {
route(3);
}
if (!t_relay()) {
sl_reply_error();
};
exit;
}
route[2]{
force_rport();
if (nat_uac_test("19")) {
if (method=="REGISTER") {
fix_nated_register();
} else {
fix_nated_contact();
};
setflag(5);
};
}
route[3] {
if (is_method("BYE|CANCEL")) {
unforce_rtp_proxy();
} else if (is_method("INVITE")){
force_rtp_proxy();
t_on_failure("1");
};
if (isflagset(5))
search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes');
t_on_reply("1");
}
failure_route[1] {
if (isflagset(6) || isflagset(5)) {
unforce_rtp_proxy();
}
}
onreply_route[1] {
if ((isflagset(5) || isflagset(6)) && status=~"(183)|(2[0-9][0-9])") {
force_rtp_proxy();
}
search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes');
if (isflagset(6)) {
fix_nated_contact();
}
exit;
}
