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?
