Hello Everyone,
I've been resolved the problem.
It was the setflag(FLT_ACC) at the beginning of the block if
(is_method("INVITE")) {
setflag(FLT_ACC); <-----
using instead following function now the dialog is correctly created.
setflag(FLT_DIALOG);
Best Regards
Angelo

Oggetto: [SR-Users] - w_ro_ccr(): Unable to find dialog and cannot do Ro
charging without it
Hello Everyone,
I'm new in Kamailio environment. We trying to setup a IMS Credit Control
Client as per RFC 4006.
We've trying to implement the suggesting configuration in ims_charging module
doc.
The Kamailio version is 5.1.1 Stable.
The Server is configured with two local users (A and B) registered on local
mysql database.
The scenario is the following:
1. In the request_route object we trying to intercept the first INVITE and
trigger
a diameter credit control request using Ro_CCR function.
2. When A calls B without triggering mechanism the call is fine.
3. When A calls B with credit control triggering, the calls failed and the
diamater request is not generated.
In the debug we find the following error:
exec: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[/etc/kamailio/kamailio.cfg]
l=540 a=25 n=xlog
ERROR: <script>: Individuato primo INVITE: generata nuova transazione

The error indicates that w_ro_ccr function doesn't find any dialog.
Following you can find the relative configuration of kamailio.cfg. The
request_route block is equal to default configuration except the following
command:
#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_DEBUG
loadmodule "cdp"
loadmodule "cdp_avp"
loadmodule "ims_charging"
loadmodule "ims_dialog"

modparam("ims_charging","interim_update_credits",30)
modparam("ims_charging","timer_buffer",5)
# -- ims_dialog params --
modparam("ims_dialog", "dlg_flag", FLT_DIALOG)
request_route {
...
if (is_method("INVITE")) {
setflag(FLT_ACC); # do accounting
t_newtran();
$var(cc_ret) = Ro_CCR("CHARGING_CCR_REPLY", "orig", 30, "1", "1");
if ($var(cc_ret) < 0) {
xlog("Chiamata a Ro_CCR() fallita\n");
sl_send_reply("402","Payment required");
exit;
}
}
...
}
route[CHARGING_CCR_REPLY]{
xlog("cca_return code is $avp(s:cca_return_code):
$avp(s:cca_result_code)\n");
switch ($avp(s:cca_return_code)){
case 1: #success
break;
case -1: #failure
switch ($avp(s:cca_result_code)){
case 4010:
send_reply("402", "Payment required - Unsufficient funds");
break;
case 5006:
send_reply("486", "Line limit exceeded");
break;
default:
send_reply("402","Payment required
($avp(s:cca_result_code))");
break;
}
default:
xlog("L_ERR", "Unknown return code from CCR:
[$avp(s:cca_return_code)] \n");
send_reply("500", "Charging Error");
break;
}
}
What's goes wrong?
Thanks in advance
