Hi Jose,
AAR is made no the reply. Reply is the place in that both media streams
in SDP are available and known. Default IMS config should be changed a
little Rx to start work. This also reminds me that you will probably
face another problem if your PCRF does not have integration w/ HSS.
P.S.
Good luck w/ PCRF battle. It is a great fun to make it work ;)
Cheers,
Ivo

Hello There,
I'm trying using the ims_qos module with PCRF for QOS, but I'm facing
some issues.
When kamailio receives an initial invite (originator), it will execute
the function -
"Rx_AAR("ORIG_SESSION_AAR","orig","",-1)", but the
PCRF
is not contacted and i see the following messages:
5(12153) DEBUG: <script>: Diameter: Orig authorizing media via Rx
5(12153) DEBUG: ims_qos [mod.c:609]: w_rx_aar(): Looking for route
block [ORIG_SESSION_AAR]
5(12153) DEBUG: ims_qos [mod.c:621]: w_rx_aar(): Rx AAR called
5(12153) DEBUG: ims_qos [mod.c:1345]: create_return_code(): Creating
return code of [-2] for aar_return_code
5(12153) DEBUG: ims_qos [mod.c:1354]: create_return_code(): created
AVP successfully : [aar_return_code]
5(12153) DEBUG: ims_qos [mod.c:627]: w_rx_aar(): Can't do AAR for
call session in request.
Why kamailio says that I Can't do AAR for call session in request?
I have looked into source code and I found that the condition that is
blocking the communication with PCRF is:
//We don't ever do AAR on request for calling scenario...
if (msg->first_line.type != SIP_REPLY) {
LM_DBG("Can't do AAR for call session in request\n");
return result;
}
Anyone can help me understand why it is happening? why it can't
proceed if isn't a reply?
Thank you for your support
BR
