Hi all, can anyone help me to find out what is wrong with my setup, i have
an asterisk behind a kamailio, kamailio is proxying all packages to the
outside.
when the call is bridge it gets disconnected after a few seconds, it seems
that our voip carrier is sending a bye because we didn't answer to their
200 ok properly, but as the trace shows we did only that kamailio is
answering to the contact header ip not the ip that is sending the ok.
any help is appreciated .
thanks.
my setup
request_route {
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
exit;
}
if(is_method("OPTIONS")) {
# send reply for each options request
sl_send_reply("200", "ok");
exit();
}
if(method=="BYE") {
#Account BYE transactions
};
if (method=="CANCEL") {
if (t_check_trans()) t_relay();
exit;
};
if (loose_route()) {
t_relay();
exit;
}
if (is_method("INVITE")) {
record_route();
}
f (!t_relay_to_udp("3.1.1.1", "5060")) {
sl_reply_error();
exit;
};
exit
};
here is a trace to a call made to a hotel.
i had changed the real ips for obvious reasons.
thanks.

I had same problem - with BYE also.
My "go around" was (replaced name of domain and IP of kamailio):
route[ACKBYE] {
#!ifdef WITH_MYFORWARD
if(($sht(forw=>$ft))=~$td){
$du=$sht(forw=>$ft);
}else
if((($td=="name.of.company.com")||($td=="ip"))&&($si=="ip")){
$du=$sht(forw=>$ft);
return;
}
#!endif
return;
}
route[PSTNINVITE] {
#!ifdef WITH_MYFORWARD
if(is_method("INVITE")){
ds_select_dst("1","4");
$sht(forw=>$ft)=$du;
sl_send_reply("100","Trying");
route(RELAY);
exit();
}
#!endif
return;
}
Meaning - during invite, I store du (to allow more then one Asterisk behind
kamailio)
and on ACK or BYE - I check td and si. Not sure I am correct, but it works
from long time, although load is not high.
PS
You will need to set in the beginning
modparam("htable", "htable",
"forw=>size=8;autoexpire=7200;")
and you need to put routes in proper places.

Thank you Stoyan, i tried but i ended up creating a loop with the carrier,
i believe this is more a asterisk receiving the package and ignoring the
record-route and because i am just proxying the signalling it does ack to
the contact, i have to find a way to tell asterisk that answer everything
to kamailio and kamailio must respond to the carrier to the proper to
header i am clueless here, now thinking to install rtpproxy to achieve
that, any other sugestions .
thanks.

Meaning - during invite, I store du (to allow more then one Asterisk
behind kamailio)
and on ACK or BYE - I check td and si. Not sure I am correct, but it works
from long time, although load is not high.
PS
You will need to set in the beginning
modparam("htable", "htable",
"forw=>size=8;autoexpire=7200;")
and you need to put routes in proper places.

I am not sure about your situation, but in my case - Asterisk respond to
any message, and wrong paths were corrected the way I showed.
By the way - I am using also rtpproxy. Although it should not interfere
here at all.
I used wireshark on Asterisk and on Kamailio servers to find what exactly
happens.
The idea is - I check "target" (for ACK and BYE) and if target is Kamailio
server, I forward package to Asterisk.
As I mentioned - I am not sure what exactly is wrong - with my setup, or
Kamailio or Asterisk - but my go around works well for me.

Thank you Stoyan, i tried but i ended up creating a
loop with the carrier,
i believe this is more a asterisk receiving the package and ignoring the
record-route and because i am just proxying the signalling it does ack to
the contact, i have to find a way to tell asterisk that answer everything
to kamailio and kamailio must respond to the carrier to the proper to
header i am clueless here, now thinking to install rtpproxy to achieve
that, any other sugestions .
thanks.
