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]:

5(12153) DEBUG: ims_qos [mod.c:1354]:
create_return_code(): created AVP successfully :

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;
}
